ABSTRACT:
A multi-layered tactile sensing skin is provided for a robotic arm or the like. The skin includes adjacent layers of electrically insulative film having opposed contiguous surfaces. An electrically conductive carbon based compound is applied uniformly to one of the surfaces, while the other surface is selectively coated with silver oxide to form a series of pairs of first and second electrically conductive regions separated from one another by a dielectric gap. The carbon based conductor bridges the gap betwen the conductive regions in each pair, permitting flow of electrical current between the regions. The current flow increases with an increase in pressure over the interface between the layers of film, and the amperage increase can be utilized to trigger a signal to the robot power supply, to decelerate, stop or reverse arm movement.
