Abstract: A composite actuator device includes a composite material that is configured to be driven by applying power thereto and that is composed of a silicone; and from 1 to 20 wt % of an iron oxide mixed in the silicone; and a metal plate that is spaced apart from the composite material by a predetermined distance. When the power is applied, the composite actuator is driven toward the metal plate by an electrostatic attractive force. Preferably, the composite actuator device has a resonance frequency of 3±0.1 Hz.
