Electrochemical actuators are devices based on materials that can expand and contract when given an electrical stimulus. For conducting polymer (CP) actuators, the design of actuators is based on the fascinating electrochemical switching properties that lead to changes in polymer volume. Their attractive features as actuators are large strain, light weight, and low voltages for actuation. In the development of CP actuators, most effort has been concentrated on improving the strain and response time. However although major advances in actuator performances have been obtained in the last few years, the actuation of CP actuator is still limited to bending movement. It restricts the application of CP actuator in semiconductor devices, position control devices, and medical instruments. So in this study, spring type CP actuator which can produce linear movement using two polypyrrrole (PPy) films having different actuation mechanism and solid polymer electrolyte (SPE) was fabricated. |
