SELF-SENSING ACTUATOR USING DIELECTRIC ELASTOMER

摘要

A sensing actuator using dielectric elastic body capable of controlling the operation of the actuator is provided to control the operation of the actuator by using physical property change of dielectric elastomer. A sensing actuator includes a driving unit, an impedance sensing unit, a power supplier and a controller for driving a micro robot. A driving unit(12) comprises a respective equipped first electrode in the upper side of a film, consisting of the film and lower-part and the second electrode. An impedance sensing unit(13) senses the impedance of the driving unit The controller controls the operation of the driving unit according to the impedance size.
