ABSTRACT:
A sensor is disclosed for sensing an applied load. The sensor includes a rigid substrate. A strain sensitive resistor is mounted to the substrate. The resistor has a pair of ends. The resistor has a length and a width that defines an area. A pair of conductors are connected to the end of the resistor. A dielectric layer is mounted over the resistor. A load transfer device is mounted to the dielectric layer. The load transfer device transfers the applied load directly to the strain sensitive resistor such that the resistor is compressed. The resistor changes resistance in response to the applied load.
