Abstract
La présente invention concerne un clavier capacitif (100) comprenant : • une couche électronique (1) comprenant au moins un capteur capacitif, • une couche métallique (2) sur la couche électronique, comprenant une surface d'appui (20) accessible à un utilisateur, • une entretoise (3) agencée entre la couche métallique (2) et la couche électronique (1), configurée pour maintenir une distance déterminée entre la couche métallique et la couche électronique, le clavier capacitif (100) étant principalement caractérisé en ce que la surface d'appui (20) de la couche métallique comprend au moins une zone d'appui (21) apte à être déformée par une pression exercée par l'utilisateur de manière à réduire la distance entre la couche métallique (2) et la couche électronique (1) à l'aplomb de ladite zone d'appui, et en ce que la couche électronique (1) est configurée pour détecter la réduction de ladite distance à l'aplomb de ladite zone d'appui (21).The present invention relates to a capacitive keyboard (100) comprising: • an electronic layer (1) comprising at least one capacitive sensor, • a metallic layer (2) on the electronic layer, comprising a bearing surface (20) accessible to a user, • a spacer (3) arranged between the metallic layer (2) and the electronic layer (1), configured to maintain a determined distance between the metallic layer and the electronic layer, the capacitive keyboard (100) being mainly characterized in that that the bearing surface (20) of the metal layer comprises at least one bearing zone (21) capable of being deformed by a pressure exerted by the user so as to reduce the distance between the metal layer (2) and the electronic layer (1) directly above said bearing zone, and in that the electronic layer (1) is configured to detect the reduction of said distance directly above said bearing zone (21).
