1. A cerebrospinal fluid shunt system comprising:

  • A valve having an electroactive polymer for said cerebrospinal shunt system, such that said electroactive polymer is an actuating element;

    An electoactive polymer transducer coupled to said valve, such that said electroactive polymer transducer is used as a pressure sensor;

    An internal control unit for processing said electroactive polymer transducer;

    An external control unit for programming the threshold pressure of said electroactive polymer;

    Whereby when the electroactive polymer transducer detects a change in pressure within the shunt assembly, the electroactive polymer transducer pressure provides an electrical voltage to the internal and external control unit, which provides a signal to the electroactive polymer actuator to adjust the valve pressure.
