Abstract
Disclosed is an electromechanical transducer and the method for manufacturing the same, which can detect or control deformation and vibration of a structure and flow of fluids by applying controlling forces. The electromechanical transducer of the present invention comprises a base substrate to which initial stress is applied; an electro-active material layer attached on the base substrate; and electrodes installed on the top and bottom side of the electro-active material layer for actuating the electro-active material layer, the base substrate and the electro-active material layer which is deformed when initial stress is removed from the base substrate so that the base substrate and the electro-active material layer have curvatures.
