Title
(EN) SENSOR AND DEVICES INCORPORATING SENSORS
(FR) CAPTEUR ET DISPOSITIFS INCORPORANT DES CAPTEURS
Abstract
(EN) This invention relates to a touch sensor having a layered structure, the layers including: a substrate; and a touch-sensitive layer formed of single-layer graphene and having a plurality of coplanar electrodes formed therein. Embodiments of the touch sensor are flexible and stretchable, making them suitable for use as an artificial skin. Further embodiments of the touch sensor are also capable of sensing pressure as well as touch. Further embodiments are substantially transparent and can therefore include a photovoltaic layer under the touch-sensitive layer which can provide a degree of energy autonomy. Further aspects of the invention provide prosthetic devices having such touch sensors forming a sensitive skin, and a method of manufacturing a touch sensor wherein interdigitated electrodes are cut in single-layer graphene by a blade-cutting process.
(FR) La présente invention concerne un capteur tactile présentant une structure en couches, les couches comprenant: un substrat; et un couche tactile formée de graphène monocouche et dans laquelle est formée une pluralité de électrodes coplanaires. Certains modes de réalisation du capteur tactile sont souples et étirables, ce qui les rend aptes à être utilisés come une peau artificielle. D'autres modes de réalisation du capteur tactile sont également capables de détecter une pression ainsi qu'un toucher. D'autres modes de réalisation sont sensiblement transparents et peuvent par conséquent inclure une couche photovoltaïque sous la couche tactile, ce qui peut apporter un certain degré d'autonomie énergétique. D'autres aspects de l'invention concernent des dispositifs prosthétiques dotés de tels capteur tactiles formant une peau sensible, et un procédé de fabrication d'un capteur tactile où des électrodes imbriquées sont découpées dans du graphène monocouche par un processus de découpe par lame.
