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. 1. A force sensing resistor comprising an external conductive layer disposed upon a contact surface of the force sensing resistor.2. The force sensing resistor of claim 1 , where the external conductive layer is a sheet metal layer.3. The force sensing resistor of claim 1 , where the external conductive layer is a metal-coated polymer layer.4. The force sensing resistor of claim 1 , where the external conductive layer is a flexible conductive material.5. The force sensing resistor of claim 5 , where the flexible conductive material is a conductive polymer.6. The force sensing resistor of claim 5 , where the flexible conductive material is a conductive elastomer.7. The force sensing resistor of further comprising a second external conductive layer disposed upon the contact surface of the force sensing resistor claim 1 , where the second external conductive layer is electrically isolated from the external conductive layer.8. The force sensing resistor of where the external conductive layer and second external conductive layer are spirals coiled around a mutual center.9. A force sensing resistor comprising:a first electrode,a flexible conductive material,a second electrode,a first conductive lead,a second conductive lead,a nonconductive encapsulation, andan external conductive layer, where:the variable conductive elastomer layer is sandwiched between the ...
