Abstract

L'invention concerne un dispositif de collecte d'énergie pour convertir une énergie mécanique en énergie électrique, comprenant un commutateur constitué d'un aimant permanent pris en sandwich par des culasses qui agissent comme des guides de flux, un noyau magnétique, une bobine électroconductrice enroulée autour du noyau et une enveloppe de blindage. Le noyau est couplé magnétiquement à l'aimant permanent à travers les culasses ; un déplacement de l'aimant entre deux positions situées à l'opposé l'une de l'autre modifie la magnétisation du noyau et, par conséquent, induit une tension dans la bobine selon la loi de Faraday. Lorsque le commutateur est dans une première position, une première culasse est en contact avec le noyau et magnétise le noyau dans une première direction. Un pressage mécanique du commutateur déplace le commutateur à l'opposé de la première position vers une seconde position et amène la seconde culasse en contact avec le noyau ce qui permet d'inverser la direction de magnétisation du noyau et d'induire une tension dans la bobine électroconductrice. Ce dispositif de collecte d'énergie miniature est destiné à être utilisé dans des commutateurs sans fil auto-alimentés.
