Abstract

Embodiments of a force sensing resistor (FSR) are disclosed. The FSR has one or more external conductive layers, applied to at least part of the contact surface of the FSR, so that when a conductive probe presses the FSR, initial zero-force contact with the FSR can be detected immediately. The external conductive layer or layers may be rigid sheet metal, flexible sheet metal, metallic-coated polymer, conductive polymer, conductive elastomer, or other conductive material. A lead or trace may be electrically coupled to the external conductive layer or layers to allow for ease of coupling to a circuit or circuit board.
