MULTIFUNCTION DERMAL DEVICE, TRANSMITTER OR REFLECTOR FOR OUTDOOR INFRARED RADIATION, IN PARTICULAR FOR MEDICAL PURPOSES, PATCH OR ARTICLE COMPRISING SAID MULTIFUNCTION
The aim of the invention is to provide medical or sanitary articles or devices made from films of polymer / ceramic composite material, which make it possible to increase the efficiency and extend the spectrum of activity of the IRLs in the prevention and control of treatment of sanitary and physiological disorders, in the improvement of the physical and / or mental performances of an individual, or in cosmetic treatments. To this end, the invention relates to a multifilette intended to be applied to the body of a living individual to emit and / or return to this body at least one far infrared radiation. This multifilette comprises at least two superimposed sheets each formed by a composite material consisting of a polymer-based matrix in which ceramic particles are dispersed capable of emitting and / or returning at least one far-infrared radiation, at least one part of these particles being preferably MnO-based particles and CoO-based particles. The invention also relates to a patch and other articles comprising the multi-layer referred to above, as well as to their manufacturing processes and their medical or other applications. cosmetics.L'invention vise à fournir des articles ou des dispositifs médicaux ou sanitaires réalisés à partir de films de matériau composite polymère/céramique, qui permettent d'accroître l'efficacité et d'étendre le spectre d'activité des IRL dans la prévention et le traitement des troubles sanitaires et physiologiques, dans l'amélioration des performances physiques et/ou mentales d'un individu, ou encore dans les traitements cosmétiques. A cet effet l'invention concerne un multifeuillet destiné à être appliqué sur le corps d'un individu vivant pour émettre et/ou renvoyer vers ce corps au moins un rayonnement infrarouge lointain. Ce multifeuillet comprend au moins deux feuillets superposés et formés chacun par un matériau composite constitué par une matrice à base de polymère dans laquelle sont dispersées des particules de céramique susc
