Electro-polymer motor
First Claim
1. An electro-polymer motor, the motor comprising:
- a fixed member;
a first actuator having a first end fixedly connected to the fixed member and a second end, the first actuator comprising a polymer positioned between two electrodes, wherein the electrodes are in communication with a power supply;
a driven member comprising a body having cylindrical shape with a cylindrical shaped aperture disposed therethrough, wherein the driven member is fixedly connected to the second end of the first actuator; and
wherein the body is disposed longitudinally along a longitudinal axis of the motor and the aperture is coaxially aligned with the longitudinal axis; and
a compressible member having a first end fixedly connected to the fixed member and a second end fixedly connected to the body of the driven member, the compressible member spaced apart from the first actuator;
wherein the first actuator changes length after the power supply applies a voltage across the electrodes to move the driven member.

Abstract
An electro-polymer motor comprising a fixed member and a first actuator having a first end fixedly connected to the fixed member and a second end is presented. The first actuator comprises a polymer positioned between two electrodes. The electrodes are in communication with a power supply. The motor also comprises a driven member comprising a first leg and a second leg such that the first leg and the second leg are separated by an axis. The driven member is fixedly connected to the second end of the first actuator. The motor also comprises a compressible member having a first end fixedly connected to the fixed member and a second end fixedly connected to the second leg of the driven member. The compressible member is spaced apart from the first actuator. The first actuator elongates after the power supply applies a voltage across the electrodes to move the driven member.
