Abstract

La présente invention concerne un dispositif de captage d'énergie faisant appel à une céramique piézoélectrique et à des aimants, dans lequel une hélice est entraînée en utilisant l'énergie éolienne, et qui est capable de produire de l'énergie au moyen de la céramique piézoélectrique en utilisant les forces d'attraction et de répulsion entre des aimants sur un support auquel un disque rotatif, les aimants et la céramique piézoélectrique sont fixés. Le dispositif de captage d'énergie faisant appel à une céramique piézoélectrique et à des aimants selon la présente invention induit une flexion de la céramique piézoélectrique et génère ainsi une tension issue de la céramique piézoélectrique, permettant ainsi le stockage d'une source d'énergie générée, la tension stockée pouvant être utilisée en tant qu'énergie excédentaire ou utilisée en tant que source d'alimentation pour l'éclairage urbain de telle sorte que l'utilisation qui est faite de l'invention puisse varier en fonction de la force du vent, c'est-à-dire de l'énergie éolienne disponible.
