1. A sensor for determining pressures of contact between the surface of said sensor and the surface of an object to be acted on, or from which action is to be received;

  • wherein said sensor is comprised of regions of capacitance, whose capacitance varies according to force applied to the contact surface of said region;

    where capacitance of said region is estabilished, at least in part, by the separation of conducting surfaces;

    wherein said seperation is maintained by compression cells, and wherein said compression cells contain only gas and provide means wherein capacitance of said regions varies linearly with external force applied to said region within the mechanical limits of said cell, and wherein said capacitance is measured by external means.
