Abstract

See full text

A dielectric elastomer vibration system includes a dielectric elastomer vibrator with a dielectric elastomer layer and a pair of electrode layers, and a power supply device producing a potential difference across the electrode layers. The vibrator exhibits various modes or regions of relationship between potential difference and deformation induced by the potential difference: a high-response region in which a relatively large deformation is induced; a low-response region of lower-potential difference in which a relatively small deformation is induced; and a low-response region of higher-potential difference in which a relatively small deformation is induced or in which a break point of the dielectric elastomer layer is included. The power supply device produces the potential difference by applying across the electrode layers a vibration signal voltage, which is generated by combining an AC voltage with a bias DC voltage corresponding to a potential difference falling in the high-response region.
