Abstract
A transducer includes a high-resistance layer that includes an elastomer and has a volume resistivity of 10Ω·cm or more, a pair of electrodes that are arranged on both a front side and a back side of the high-resistance layer and include a binder and a conductive material, and a medium-resistance layer that is interposed between the electrode and the high-resistance layer on at least one of the front side and the back side of the high-resistance layer, includes an elastomer, and has a volume resistivity that is smaller than the volume resistivity of the high-resistance layer by two or more digits. In the transducer, the medium-resistance layer is interposed between at least one electrode and the high-resistance layer to take advantage of the resistance to dielectric breakdown originally possessed by the high-resistance layer, thereby obtaining a larger force by applying a higher voltage.
