ABSTRACT:
A capacitive tactile sensor array is formed of capacitive plates formed on a dielectric substrate, on which large area electronics is also deposited. A conductive film is spaced from the capacitive plates, to form the other plates of the sensor capacitors. This conductive film may be grounded. The large area electronics includes a circuit that provides outputs corresponding to the pressure applied to each of the sensor capacitors. A method is also disclosed for controlling the circuit to provide an output corresponding to the pressure applied to the conductive film.
