▎ 摘　　要

NOVELTY - The touch sensor comprises a layered structure that is provided with a substrate. A touch-sensitive layer is formed of single-layer graphene and multiple coplanar electrodes. A coating layer is formed on top of the touch-sensitive layer. The coating layer is formed of a polymer. A sensor is sensitive to pressure as well as touch. A capacitance between the electrodes varies in relation to the pressure applied to the sensor. The coplanar electrodes are interdigitated. The layers of the touch sensor are substantially transparent to near-infrared, visible and ultra-violet radiation. A photovoltaic layer is provided for converting ambient radiation into electrical power. The touch-sensitive layer and polymer layer are stacked on top of the photovoltaic layer. A detection circuit is configured to provide an output from the touch-sensitive layer. The detection circuit is partly powered by the photovoltaic layer. USE - Touch sensor for providing touch sensitivity on a prosthetic or robotic device (Claimed). ADVANTAGE - The performance of the sensor is improved by introducing a dielectric layer above the touch-sensitive layer. The damage to the properties of the graphene is eliminated in the areas surrounding the cut. The harmful effects on atomically thick graphene layers are reduced. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a prosthetic or robotic device; and (2) a method for manufacturing a touch sensor.
