    TEXTILE ELECTRONIC DEVICE FOR SMART CLOTHING
    FIELD OF THE INVENTION
    The present invention relates to a textile electronic device suitable for smart clothes and a garment comprising such a device.
    STATE OF THE ART
    Smart clothes and textiles need to integrate electronics on supports compatible with textile constraints. To withstand these constraints, electronic equipment must be flexible, waterproof, and must not be too thick, which could interfere with the user. The electronics must also be able to withstand all the constraints undergone by the textile or clothing in its daily use (handling, washing, drying, folding ...).
    Smart clothes often involve taking on electronic circuits. Electronic circuits include a set of electronic components often interconnected using a printed circuit. Electronic circuit technology has been developed for many years to become a mature technology today, with reasonable cost, effective quality control, and the ability to integrate a high number of components compared to other technologies such as systems. on chips (SOC). Another advantage in the use of electronic circuits is their interchangeability, for example, after the deterioration of a garment.
    It is therefore necessary to find a way to connect the electronic circuit to the textile. Several alternatives exist but still have many drawbacks.
    First, there is the possibility of connecting the conductive threads of the textile to the tracks of the electronic circuit by welding in order to connect the conductive area of the textile to the electronic circuit. This process makes it possible to limit both the size and the mass of the devices connected to the textile. However, the process of welding each component to each thread or conductive part of the textile is long and difficult to automate. In addition, this method tends to concentrate the stresses at the weld axis and increases the risk of breakage of the conductive wire of the welded fabric.
    A method is also known which consists in installing clasps for connecting the electronic device and the textile. The clasp is thus detachably connected, on one side to the textile, on the other to the electronic circuit. However, the connection is made only on one or more points; which makes the connection fragile in the event of stresses on one end of the device and makes the connection unstable. In addition, the rigidity inherent in such a method and the volume occupied by the device can cause discomfort for the user and further weaken the connection.
    There is also the possibility of mounting an electronic circuit directly on the textile, and of sewing metallic threads at the interconnection with the electronic circuit (C. Kallmayer, T. Linz, R. Aschenbrenner, and H. Reichl. System integration technologies for smart textiles, mst news, 2: 42-43, 2005.). However, this technique seems difficult to carry out on an industrial scale and does not allow the replacement of the electronic circuit, or conversely, the detachment of the flexible electronic circuit to connect it to another textile.
    The present invention therefore aims to develop a new device comprising an electronic circuit connected to a textile, allowing an efficient electrical and mechanical connection, capable of withstanding the stresses that the textile or the clothing can be brought to undergo in its daily use. The present invention aims, at the same time, to create a computer, which is both flexible and adapted to the life cycle of a textile worn in contact with the skin of the user. The present invention also aims to propose a method for manufacturing a flexible electronic circuit suitable for smart clothing. The device according to the present invention must be able to attach and detach from the electronic textile without the implementation of complex operations or without the intervention of a technician, so that the user can carry out these operations himself. without difficulties. The device according to the present invention must be able to be worn by the user of the textile without any discomfort while ensuring the normal daily use of the garment produced with this textile.
