Abstract

La présente invention concerne une unité active électrique (100) pour générer un effet physique tel que de la chaleur, du froid ou une émission de lumière, qui trouve une application particulière dans un système de régulation de température pour réguler la température du corps, ou dans un système d'émission de lumière destiné à être porté par une telle partie du corps. L'unité active électrique (100) comprend un support textile (102) supportant : un élément actif (101) conçu pour générer ledit effet physique ; au moins un point de connexion électrique (104) conçu pour être connecté à une source d'alimentation et à une unité de commande, et situé sur ledit élément actif (101) ; un capteur (106) conçu pour être connecté à la source d'alimentation et à l'unité de commande, de telle sorte que l'unité active électrique peut être connectée à la source d'alimentation et à l'unité de commande par l'intermédiaire du point de connexion afin de permettre l'alimentation de l'élément actif par la source d'alimentation et l'activation/la désactivation dudit élément actif par l'unité de commande en fonction des données détectées par le capteur. Le support textile (102) présente une première face et une seconde face en regard de ladite première face, le ou les points de connexion (104) étant situés uniquement sur la première face, l'élément actif (101) étant intégré dans le support textile (102) de manière à former un motif déterminé sur les première et seconde faces. Le motif peut éviter un courant électrique émis depuis les points de connexion (104) à travers la seconde face, ce qui permet d'éviter un contact direct entre la peau et les points chauds situés au niveau des points de connexion (104).
