Title (EN) A TACTILE SENSOR AND A METHOD OF MANUFACTURING THEREOF
(FR) CAPTEUR TACTILE ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract:
(EN) A capacitive or resistive tactile sensor having a conductive membrane, a flexible dielectric or weakly conductive sheet and a substrate having electrodes, and a method of manufacturing thereof. The flexible sheet has a first surface and an opposite second surface, the first surface and the second surface are uniformly distanced when at rest. The first surface is adapted to contact one of the conductive membrane or the substrate. The second surface is adapted to contact another one of the conductive membrane or the substrate. The body defines between the first and second surfaces, at a predetermined region, a plurality of laser ablated uniform cavities that are evenly distributed and operatively identical in order to provide a known compression index at the predetermined region of the flexible sheet. The substrate has uniformly distributed static pressure sensing electrodes and at least one uniformly spread dynamic pressure sensing electrode, which is located between the static pressure sensing electrodes, and is used for measuring a voltage or a current variation with the conductive membrane according to the deformation of the flexible sheet.
(FR) L'invention concerne un capteur tactile capacitif ou résistif ayant une membrane conductrice, une feuille souple diélectrique ou faiblement conductrice et un substrat ayant des électrodes, et un procédé de fabrication associé. La feuille souple a une première surface et une seconde surface opposée, la première surface et la seconde surface étant espacées uniformément au repos. La première surface est conçue pour entrer en contact avec un élément parmi la membrane conductrice et le substrat. La seconde surface est conçue pour entrer en contact avec l'autre élément parmi la membrane conductrice et le substrat. Le corps définit entre les première et seconde surfaces, au niveau d'une région prédéfinie, une pluralité de cavités uniformes ayant subi une ablation au laser qui sont réparties uniformément et fonctionnellement identiques afin de fournir un indice de compression connu au niveau de la région prédéfinie de la feuille souple. Le substrat comporte des électrodes de détection de pression statique uniformément répartie et au moins une électrode de détection de pression dynamique uniformément dispersée, qui est située entre les électrodes de détection de pression statique, et sert à mesurer une tension ou une variation de courant avec la membrane conductrice en fonction de la déformation de la feuille souple.
