ABSTRACT:
A pressure sensing device constructed of a high molecular conductor kept in contact at all times with at least one pair of electrodes in a circuit and wherein the resistance of the conductor is sensitive to external forces oppositely applied by an actuator and a spring. Changing of the relative value of the forces changes the conductor resistance thus changing the circuit resistance.
