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).
