Patent abstract
An actuator includes a non-magnetic, electroactive material that is suitable to impart force upon application of an electric current, a power supply to provide an electric current to the electroactive material and a controller in operative connection with the power supply to control application of electric current to the electroactive material. In one embodiment, the controller is adapted to limit rates at which electric current is applied to or removed from the electroactive material to predefined rates, thereby reducing the potential for high frequency harmonic emissions.
