    [001] [001] The present disclosure relates to aerosol delivery devices, such as aerosol-producing tobacco articles. The tobacco articles can be configured to dispense with an aerosol precursor, which can incorporate materials that can be made or derived from, or otherwise incorporate tobacco, the precursor being able to form an inhalable substance for human consumption. FUNDAMENTALS
    [002] [002] Many devices have been proposed over the years as improvements or alternatives to tobacco products that require combustion of tobacco for use. Many of these devices have been designed to provide the sensations associated with cigarette, cigar or pipe smoking, but without providing considerable amounts of incomplete products of combustion and pyrolysis resulting from tobacco burning. To that end, numerous smoke products, flavor generators and alternative medical inhalers have been proposed that use electrical energy to vaporize or heat a volatile material or try to provide the sensations of smoking a cigarette, cigar or pipe without burning tobacco to a significant degree. See, for example, the various alternative smoking articles, aerosol delivery devices and heat generating sources, presented in the prior art described in U.S. Patent 8,881,737 to Collett et al., U.S. Patent Application Publication 2013 / 0255702 by Griffith Jr. et al., US Patent Application Publication 2014/0000638 by Sebastian et al., US Patent Application Publication 2014/0096781 by Sears et al., Publication of

    [0026] [0026] These and other resources, aspects and advantages of the present disclosure will be evident from the reading of the detailed description below, together with the attached drawings, which are briefly described below. The present disclosure includes any combination of two, three, four or more features or elements set forth in this disclosure, regardless of whether those features or elements are expressly combined or otherwise recited in a specific example implementation described herein. This disclosure is intended to be read holistically, so that any resources or elements separable from the disclosure, in any of its aspects and example implementations, are seen as combinable, unless the context of the disclosure clearly indicates otherwise.
    [0027] [0027] Therefore, it will be appreciated that this Brief Summary is provided only for the purpose of summarizing some example implementations, in order to provide a basic understanding of some aspects of disclosure. Therefore, it will be appreciated that the example implementations described above are merely examples and should not be construed to restrict the scope or spirit of the disclosure in any way. Other example implementations, aspects and advantages will be evident from the detailed description below, taken in conjunction with the attached drawings, which illustrate, by way of example, the principles of some example implementations described. BRIEF DESCRIPTION OF THE DRAWINGS
    [0028] [0028] Having thus described the disclosure in the general terms mentioned above, reference will now be made to the attached drawings, which are not necessarily drawn to scale and in which:
    [0029] [0029] Figure 1 illustrates a side view of an aerosol delivery device including a cartridge coupled to a control body, according to an example implementation of the present disclosure;

    [0031] [0031] Figures 3, 4 and 5 illustrate various elements of the aerosol delivery device according to various example implementations. DETAILED DESCRIPTION
    [0032] [0032] The present disclosure will now be described in more detail hereinafter with reference to example implementations thereof. These example implementations are described so that this disclosure is thorough and complete and fully transmits the scope of the disclosure to those skilled in the art. In fact, disclosure can be incorporated in many different ways and should not be construed as limited to the implementations set forth herein; instead, these implementations are provided in order for this disclosure to meet applicable legal requirements. As used in the specification and the appended claims, the singular forms "one", "one", "o" and the like include plural referents, unless the context clearly indicates otherwise. In addition, although reference may be made here to quantitative measurements, values, geometric relationships or the like, unless otherwise stated, any one or more, if not all, may be absolute or approximate to take into account acceptable variations that may occur, such as those due to engineering tolerances or the like.
    [0033] [0033] As described below, example implementations of the present disclosure refer to aerosol delivery devices. Aerosol delivery devices according to the present disclosure use electrical energy to dispense a material (preferably without burning the material to a significant degree) in the form of an inhalable substance; and the components of such systems are in the form of articles most preferably they are compact enough to be considered portable devices. That is, the use of components of preferred aerosol delivery devices does not result in the production of smoke, in the sense that the aerosol results mainly from by-products of tobacco combustion or pyrolysis, but on the contrary, the use of these preferred systems results in the production of an aerosol resulting from the passage of certain components incorporated in it through a vibrating piezoelectric or piezomagnetic mesh. In some example implementations, the components of aerosol delivery devices can be characterized as electronic cigarettes, and these electronic cigarettes preferably incorporate tobacco and / or tobacco derived components and therefore deliver tobacco derived components in the form of an aerosol.
    [0034] [0034] Aerosol-generating parts of certain preferred aerosol delivery devices can provide many of the sensations (eg, inhalation and expiration rituals, types of tastes or flavors, organoleptic effects, physical sensation, usage rituals, visual cues, such as those provided by the visible aerosol, and the like) of smoking a cigarette, cigar or pipe that is used to light and burn tobacco (and therefore inhale cigarette smoke), without any substantial degree of combustion of any component thereof. For example, the user of an aerosol generating piece of the present disclosure can hold and use that piece as a smoker employs a traditional type of smoking article, suck at one end of the piece for inhaling the aerosol produced by that piece, take or suck blows at selected and similar time intervals.
    [0035] [0035] Although systems are generally described here in terms of implementations associated with aerosol delivery devices, such as so-called "electronic cigarettes", it should be understood that mechanisms, components, resources and methods can be incorporated in many different ways and associated with a variety of articles. For example, the description provided in this document can be used in conjunction with implementations of traditional smoking articles (for example, cigarettes, cigars, pipes, etc.), cigarettes that heat without burning, and related packaging for any of the products disclosed herein. . Therefore, it should be understood that the description of the mechanisms, components, resources and methods disclosed herein is discussed in terms of implementations related to aerosol delivery devices by way of example only, and can be incorporated and used in several other products and methods .
    [0036] [0036] The aerosol delivery devices of the present disclosure can also be characterized as being articles of steam production or articles of delivery of medicines. Thus, these articles or devices can be adapted to provide one or more substances (for example, tastes and / or active pharmaceutical ingredients) in an inhalable form or state. For example, inhalable substances can be substantially in the form of an aerosol (i.e., a suspension of fine solid particles or liquid droplets in a gas). Alternatively, inhalable substances can be in the form of vapor (ie,
    [0037] [0037] In use, the aerosol delivery devices of this disclosure may be subject to many of the physical actions employed by an individual in the use of a traditional type of smoking article (for example, a cigarette, cigar or pipe that is used for lighting and inhaling tobacco). For example, the user of an aerosol delivery device of the present disclosure can hold this article in the same way as a traditional type of smoking article, suck at one end of that article for aerosol inhalation produced by that article, take puffs at intervals selected time frames, etc.
    [0038] [0038] The aerosol delivery devices of the present disclosure generally include various components provided within an outer body or housing, which can be referred to as a housing. The overall design of the outer body or shell may vary, and the shape or configuration of the outer body that can define the size and general shape of the aerosol delivery device may vary. Typically, an elongated body similar to the shape of a cigarette or cigar can be formed from a single unitary compartment or the elongated compartment can be formed by two or more separable bodies. For example, an aerosol delivery device may comprise an elongated housing or body which may be substantially tubular in shape and, as such, resemble the shape of a conventional cigarette or cigar. In one example, all components of the aerosol delivery device are contained in a housing. Alternatively, an aerosol delivery device can comprise two or more housings that are joined and are separable. For example, an aerosol delivery device may have, at one end, a control body comprising a housing containing one or more reusable components, for example, an accumulator such as a rechargeable battery and / or rechargeable supercapacitor, and several components electronics to control the operation of this article), and at the other end and removably attachable to it, a body or outer shell containing a disposable portion (for example, a disposable cartridge containing flavor) More specific component formats, configurations and arrangements within the type of single housing unit or within a type of housing separable from several parts will be evident in light of the additional disclosure provided in this document. In addition, various designs of aerosol delivery devices and component arrangements can be appreciated considering the electronic aerosol delivery devices available on the market.
    [0039] [0039] The aerosol delivery devices of the present disclosure preferably comprise some combination of an energy source (i.e., an electrical energy source), at least one control component (for example, means for triggering, controlling, regulating and cease energy for aerosol disbursement, as for controlling the electric current flowing from the energy source to other components of the article - for example, a microprocessor, individually or as part of a microcontroller), a vibrating piezoelectric or piezomagnetic mesh, which in isolation or in combination with one or more additional elements they may be commonly referred to as an "atomizer", an aerosol precursor composition (for example, usually a liquid capable of producing an aerosol upon disbursement through a vibrating piezoelectric or piezomagnetic mesh, as ingredients commonly referred to as "smoke juice", "electronic liquid" and "electronic juice"), and a region or p mouth end tab to allow suction of the aerosol delivery device for aerosol inhalation (for example, an air flow path defined through the article such that the generated aerosol can be removed from it by suction).
    [0040] [0040] The alignment of the components within the aerosol delivery device of the present disclosure may vary. In specific implementations, the aerosol precursor composition can be located near an end of the aerosol delivery device that can be configured to be positioned close to a user's mouth, in order to maximize aerosol delivery to the user. Other settings, however, are not deleted. Generally, the piezoelectric / piezomagnetic mesh can be positioned sufficiently close to the aerosol precursor composition, so that when the mesh is vibrating, the aerosol precursor (as well as one or more flavorings, medications or the like that can also be supplied for delivery to a user) is dragged through the mesh and forms an aerosol for delivery to the user.
    [0041] [0041] As noted above, the aerosol delivery device can incorporate a battery or other source of electrical energy to provide sufficient current flow to provide various features to the aerosol delivery device, such as feeding a piezoelectric / piezomagnetic mesh, feeding control systems, indicator feeding, and the like. The power source can take on several implementations. Preferably, the energy source is capable of providing sufficient energy to cause the piezoelectric / piezomagnetic mesh to rapidly vibrate to provide aerosol formation and energize the aerosol delivery device through use for a desired period of time. The energy source is preferably sized to fit conveniently within the aerosol delivery device, so that the aerosol delivery device can be easily handled. In addition, a preferred energy source is light enough to not harm a desirable smoking experience.
    [0042] [0042] More specific formats, configurations and arrangements of components within the aerosol delivery devices of the present disclosure will be evident in light of the additional disclosure provided below. In addition, the selection and arrangement of various components of the aerosol delivery device can be appreciated considering the electronic aerosol delivery devices available on the market. Additional information on component shapes, configurations and arrangements within the aerosol delivery devices of this disclosure, as well as commercially available electronic aerosol delivery devices, can be found in PCT Patent Application Publication WO 2015/168588 by Ademe et al . and U.S. Patent Application Serial No. 15 / 291,771 to Sur et al., filed on October 12, 2016, which are hereby incorporated by reference.
    [0043] [0043] Figure 1 illustrates a side view of an aerosol delivery device 100 including a control body 102 and a cartridge 104, according to several example implementations of the present disclosure. In particular, Figure 1 illustrates the control body and the cartridge coupled to each other. The control body and the cartridge can be strikingly aligned in a functional relationship. Various mechanisms can connect the cartridge to the control body to result in a threaded fit, a pressure fit, an interference fit, a magnetic fit or the like. The aerosol delivery device may be substantially rod-like, substantially tubular or substantially cylindrical in some example implementations when the cartridge and the control body are in an assembled configuration. The aerosol delivery device can also be substantially rectangular, rhomboidal or triangular in cross-section, multifaceted or similar shapes, some of which may lend themselves to greater compatibility with a substantially flat or thin film energy source, as a source of including a dead battery.
    [0044] [0044] Control body 102 and cartridge 104 may include respective housings or separate external bodies, which may be formed from any one of several different materials. The housing can be formed from any structurally suitable material. In some instances, the housing may be formed of a metal or alloy, such as stainless steel, aluminum or the like. Other suitable materials include various plastics (e.g., polycarbonate), metal coating on plastic, ceramics and the like.
    [0045] [0045] In some example implementations, one or both of the control body 102 or the cartridge 104 of the aerosol delivery device 100 may be referred to as being disposable or as being reusable. For example, the control body may have a replaceable battery, a rechargeable battery (for example, a thin film rechargeable solid-state battery) or a rechargeable supercapacitor and therefore can be combined with any type of charging technology, including connection to a typical wall outlet, connection to a car charger (for example, a cigarette lighter receptacle), connection to a computer, such as via a universal serial bus (USB) cable or connector, connection to a photovoltaic cell (sometimes called a solar cell) or solar panel of solar cells, wireless connection to a radio frequency (RF), wireless connection to induction-based charging boards, or connection to an RF to DC converter.
    [0046] [0046] Figure 2 more particularly illustrates the aerosol delivery device 100, according to some example implementations. As seen in the sectional view illustrated therein, again, the aerosol delivery device may comprise a control body 102 and a cartridge 104, each of which includes a number of respective components. The components illustrated in Figure 2 are representative of the components that may be present in a control body and cartridge and are not intended to limit the scope of the components that are covered by the present disclosure. As shown, for example, the control body can be formed by a control body housing 206 which can include a control component 208 (for example, a microprocessor, individually or as part of a microcontroller), an input device 210 , a power source 212 and one or more light-emitting diodes (LEDs) 214, LEDs enabled with quantum dots or the like, and these components can be aligned in a variable manner. Examples of a suitable control component include Microchip Technology Inc. PICl6 (L) F1713 / 6 microcontrollers, described in Microchip Technology, Inc., AN2265, Mesh Nebulizer Reference Design
    [0047] [0047] The power source 212 may include, for example, a battery (disposable or rechargeable), rechargeable supercapacitor, rechargeable solid state battery (SSB), rechargeable lithium ion battery (LiB) or similar, or some combination of themselves. Some examples of a suitable energy source are provided in U.S. Patent Application Serial No. 14 / 918,926 to Sur et al., Filed on October 21, 2015, which is incorporated herein by reference. Other examples of a suitable energy source are provided in the U.S. Patent Application Publication 2014/0283855 by Hawes et al., US Patent Application Publication 2014/0014125 by Fernando et al., US Patent Application Publication 2013/0243410 by Nichols et al., US Patent Application Publication 2010/0313901 by Fernando et al. and US Patent Application Publication 2009/0230117 by Fernando et al., all of which are incorporated herein by reference.
    [0048] [0048] LED 214 can be an example of a suitable visual indicator with which the aerosol delivery device 100 can be equipped. Other indicators, such as audio indicators (for example, speakers), haptic indicators (for example, vibration motors) or the like, can be included in addition to or as an alternative to visual indicators, such as LED, quantum dot-enabled LEDs .
    [0049] [0049] The cartridge 104 may be formed of a cartridge shell 216 surrounding a reservoir 218 configured to retain the precursor aerosol composition, and including a nozzle 220 having a piezoelectric / piezomagnetic mesh. In many configurations, this structure can be called a tank; and, therefore, the terms "cartridge", "tank" and the like can be used interchangeably to refer to a wrapper or other housing involving a reservoir for the aerosol precursor composition and includes a nozzle.
    [0050] [0050] Reservoir 218 illustrated in Figure 2 can be a container or it can be a fibrous reservoir, as currently described. the reservoir may be in fluid communication with the nozzle 220 for the transportation of an aerosol precursor composition stored in the reservoir housing for the nozzle. An opening 222 may be present in the cartridge housing 216 (for example, at the mouth end) to allow the aerosol formed from the cartridge 104 to exit.
    [0051] [0051] In some examples, a transport element can be positioned between the reservoir 218 and the nozzle 220, and configured to control an amount of aerosol precursor composition passed or delivered from the reservoir to the nozzle. In some examples, a microfluidic chip can be incorporated into cartridge 104, and the amount and / or mass of precursor aerosol composition delivered from the reservoir can be controlled by one or more microfluidic components. An example of a microfluidic component is a micro pump 224, as one based on micro-electromechanical systems (MEMS) technology. Examples of suitable micro pumps include the micro pump model MDP2205 and others from thinXxxs Microtechnology AG, the micro pumps of model mp5 and mp6 and others from Bartels Mikrotechnik GmbH, and piezoelectric pumps from Takasago Fluidic Systems.
    [0052] [0052] As also shown, in some examples, a microfilter 226 can be positioned between the micro pump 22 4 and the nozzle 220 to filter the aerosol precursor composition delivered to the nozzle. Like the micro-pump, the microfilter is a microfluidic component. Examples of suitable microfilters include continuous flow microfilters, manufactured using laboratory techniques on a chip (LOC).
    [0053] [0053] In use, when input device 210 detects user input to activate the aerosol delivery device, the piezoelectric / piezomagnetic mesh is activated to vibrate and thus suck the aerosol precursor composition through the mesh. This forms droplets of aerosol precursor composition that combine with air to form an aerosol. The aerosol is moved, aspirated or otherwise removed from the mesh and out of the opening 224 at the mouth end of the aerosol delivery device.
    [0054] [0054] In some examples, the aerosol delivery device 100 may include a number of additional software-controlled functions. For example, the aerosol delivery device may include a power source protection circuit configured to detect power source input, loads at the power source terminals, and load input. The power source protection circuit may include short circuit protection, undervoltage blocking and / or overvoltage load protection, battery temperature compensation. The aerosol delivery device can also include components for measuring ambient temperature, and its control component 208 can be configured to control at least one functional element to inhibit the charging of the power source - particularly any battery - if at room temperature is below a certain temperature (for example, 0 ºC) or above a certain temperature (for example, 45 ºC) before starting charging or during charging.
    [0055] [0055] In addition or alternatively, in some examples, the energy delivery of the energy source 212 may vary over each breath in the aerosol delivery device 100 according to an energy control mechanism. The device may include a "long breath" safety timer, so that in the event of a user or component failure (for example, input device 210), cause the aerosol delivery device to attempt to blow continuously, the control component 208 can control at least one function to terminate the blow automatically after a period of time (e.g., four seconds). In addition, the time between blows in the aerosol delivery device can be restricted to less than a period of time (e.g., 100 seconds). A watchdog safety timer can automatically reset the aerosol delivery device if the control component or the software running on it becomes unstable and does not meet the timer within an appropriate time interval (for example, eight seconds). Additional safety protection can be provided in the event of a defective or otherwise defective input device 210, such as permanently disabling the aerosol delivery device, in order to prevent inadvertent aerosol delivery. A breath limiting switch can disable the device in the event of a failure in the input device, causing the device to activate continuously without stopping after the maximum four seconds of blowing time.
    [0056] [0056] The aerosol delivery device 100 may include a blowing tracking algorithm configured to block the nozzle 220 from the aerosol delivery, once a defined number of breaths have been achieved for a connected cartridge (based on number of available breaths calculated in light of the charge of electronic liquid in the cartridge). The aerosol delivery device may include a sleep, standby or low power consumption function, whereby the delivery of energy can be automatically stopped after a defined period of non-use. Additional safety protection can be provided, in which all charge / discharge cycles of the power source 212 can be monitored by the control component 208 over its lifetime. After the power source reaches the equivalent of a predetermined number (for example, 200) of complete discharge and full recharge cycles, it can be declared depleted, and the control component can control at least one functional element to prevent charging additional power source.
    [0057] [0057] The various components of an aerosol delivery device in accordance with the present disclosure can be chosen from among the components described in the art and commercially available. Examples of batteries that can be used in accordance with the disclosure are described in U.S. Patent 9,484,155 to Peckerar et al., Which is incorporated herein by reference.
    [0058] [0058] The aerosol delivery device 100 may incorporate the input device 210, such as a switch, sensor or detector for controlling electrical power supply to the piezoelectric / piezomagnetic mesh of the nozzle 220 when aerosol generation is desired (for example , upon suction during use).

    [0065] [0065] In some examples, the control component 208 includes several electronic components and, in some examples, it can be formed on an electronic printed circuit board (PCB) that supports and electrically connects the electronic components. Electronic components can include a microprocessor or processor core and memory. In some examples, the control component may include a microcontroller with an integrated processor core and memory, and may also include one or more integrated input / output peripherals. In some examples, the The control component can be coupled to a communication interface 228 to enable wireless communication with one or more networks, computing devices or other devices that are properly enabled.

    [0066] [0066] Figures 3 and 4 illustrate various elements of the aerosol delivery device 100, according to several example implementations. As shown, the control component 208 can include a microprocessor 330, a pulse regulator 332 and an electronic oscillator 334. In some examples, as shown in Figure 3, the nozzle 220 includes a piezoelectric material 336 surrounding a mesh
    [0067] [0067] In some examples, the 212 power source is a rechargeable battery (for example, LiB) having a nominal voltage between 3.7 and 4.1 volts. In some examples, a buck-boost converter is connected to the 212 power source, between the power source and its load. The buck-boost converter allows sufficient current from the battery to drive the 336/436 piezoelectric / piezomagnetic material to vibrate, even for voltages below 2.7 volts. This, in turn, facilitates the use of more output from a single load from the power source and greater efficiency for its output. An example of a suitable buck-boost converter is the model ADP1614, CC-CC configuration converter from Analog Devices.
    [0068] [0068] Looking briefly at Figure 2, in examples including micro-pump 224, the micro-pump is close to the reservoir of mesh 338 to deliver precursor composition of aerosol from the reservoir to the mesh for discharging its components. Likewise, in examples including microfilter 226, the microfilter is close to the mesh reservoir side to filter the aerosol precursor composition delivered from the reservoir to the mesh for discharging its components. And in examples, including both the micro pump and the microfilter, the microfilter is between the micro pump and the mesh to filter the aerosol precursor composition supplied from the reservoir to the mesh.
    [0069] [0069] Returning to Figures 3 and 4, the microprocessor 330 is coupled to and configured to drive the piezoelectric / piezomagnetic material 336/436 to vibrate and cause a discharge of components of aerosol precursor composition (from the reservoir 218) through the mesh 338 and thus produce an aerosol for inhalation by a user.
    [0070] [0070] According to example implementations of the present disclosure, the components of the precursor composition of aerosol discharged through the mesh 338 have a diameter of less than one micrometer. In some instances, the 336/436 piezoelectric / piezomagnetic material has a resonant frequency of up to 400 megahertz. In some examples, piezoelectric or piezomagnetic material has a resonant frequency of 1,000 kilohertz (up to 400 megahertz) and the mesh is a MEMS device. In other examples, the piezoelectric / piezomagnetic material has a resonant frequency of 130 kilohertz, (up to 400 megahertz), and the mesh is a stainless steel mesh. And in some instances, the mesh has a curved surface.
    [0071] [0071] The impulse regulator 332 is between the power source 212 and an electrical charge that includes the piezoelectric / piezomagnetic material 336 / 436. The impulse regulator is configured to increase the voltage output of the power source to a higher voltage. high, and microprocessor 330 is configured to drive the impulse regulator to emit the highest voltage to power the piezoelectric / piezomagnetic to vibrate.
    [0072] [0072] The electronic oscillator 334 is coupled to and between the microprocessor 330 and piezoelectric / piezomagnetic material 336/436, and the microprocessor is configured to drive the electronic oscillator to produce a periodic oscillating electronic signal to drive the piezoelectric / piezomagnetic material at a frequency resonance. In some examples, the microprocessor is configured to emit a pulsating signal to trigger the electronic oscillator to produce the periodic electronic oscillating signal, with the pulsating signal having a programmable duty cycle. The frequency of the periodic oscillating electronic signal depends on the duty cycle and, when programming the duty cycle, the periodic frequency oscillating electronic signal can also be programmed to allow the use of piezoelectric / piezomagnetic material with different resonant frequencies. In some examples, the microprocessor is configured to control the electronic oscillator to produce the periodic oscillating electronic signal having a frequency of 1,000 kilohertz (up to 400 megahertz) which corresponds to the resonance frequency of the piezoelectric / piezomagnetic material.
    [0073] [0073] In some examples, as shown in Figure 3, the electronic oscillator 334 is electrically coupled to the piezoelectric material 336 and configured to produce the periodic oscillating electronic signal to drive the piezoelectric material to vibrate. In other examples, as shown in Figure 4, the phase divider 440 configured to receive the periodic oscillating electronic signal from the electronic oscillator and produce a pair of periodic oscillating electronic signals that are antiphasic (i.e., 180 degrees apart). In these other examples, the phase divider is configured to produce the periodic oscillating electronic signal pair to drive the pair of magnets 442 to produce periodic oscillating magnetic fields that are antiphasic and thus drive the piezomagnetic material 436 to vibrate.
    [0074] [0074] In the examples, including both impulse regulator 332 and electronic oscillator 334, the electronic oscillator is coupled to and between the impulse regulator and piezoelectric / piezomagnetic material 336 / 436. In these examples, microprocessor 330 is configured to drive the impulse regulator to emit the highest voltage to power the electronic oscillator to produce a periodic oscillating electronic signal to drive the piezoelectric / piezomagnetic material to vibrate at a resonant frequency. In some examples, the microprocessor is configured to emit a pulsating signal to drive the impulse regulator and thus the electronic oscillator to produce the periodic oscillating electronic signal, with the pulsating signal having a programmable duty cycle. And in some instances, the microprocessor is configured to control the electronic oscillator to produce the periodic oscillating electronic signal having a frequency of 1,000 kilohertz (up to 400 megahertz) which corresponds to the resonance frequency of the piezoelectric / piezomagnetic material.
    [0075] [0075] In some examples, as shown in Figure 5, control component 208 also includes a current sensor 544 configured to measure electrical current through piezoelectric / piezomagnetic material 336 /
