1. A generator for converting mechanical energy to electrical energy, the generator comprising:

  • at least two electrodes; and

    an electroactive polymer arranged in a manner which causes a change in electric field in response to a deflection applied to a first portion of the electroactive polymer wherein an energy change resulting from the deflection of the electroactive polymer is converted to electrical energy which is removed at the two electrodes and wherein the electroactive polymer has an elastic modulus at most about 100 MPa without electrical energy applied thereto.
