ABSTRACT:
A high-resolution pressure-sensing device is disclosed. The device includes an insulating flexible matrix having a plurality of filler particles. Application of a force to the matrix causes compression of the matrix. This results in the filler particles occupying a greater amount of space within the matrix relative to when no force is applied. A detector attached to the matrix detects or measures the volume of the filler particles relative to the volume of the matrix, and therefore determines the force applied to the matrix. Preferably, the resistivity of the matrix is inversely proportional to the volume percent of the filler particles, in which case the detector is a resistance-measuring circuit.
