Abstract
(EN)
Disclosed are one or more proximity sensors. At least one of the proximity sensors includes a first dielectric layer, an electrically conductive layer, and an electrode. The first dielectric layer includes an inner surface and an outer surface. The electrically conductive layer is positioned proximate to one of the inner surface or the outer surface of the first dielectric layer. The electrode includes an outer surface. The outer surface of the electrode is positioned proximate the inner surface of the first dielectric layer. The outer surface of the electrode and the electrically conductive layer define a gap.

Sont ici décrits un ou plusieurs capteur(s) de proximité. Au moins l'un des capteurs de proximité comprend une première couche diélectrique, une couche conductrice et une électrode. La première couche diélectrique comprend une surface interne et une surface externe. La couche conductrice est positionnée à proximité de l'une de la surface interne ou de la surface externe de la première couche diélectrique. L'électrode comprend une surface externe. La surface externe de l'électrode est positionnée à proximité de la surface interne de la première couche diélectrique. La surface externe de l'électrode et la couche conductrice définissent un espace.
