Abstract (en)

[origin: WO2007003048A1] A dielectric polymer actuator comprising a first portion, a second portion, a dielectric polymer roll composed of at least two dielectric polymer sheets each having a negative side and a positive side and a positive electrode terminal electrically connected to the positive side of the dielectric polymer sheets and a negative electrode terminal electrically connected to the negative side of the dielectric polymer sheets. The dielectric polymer roll is positioned relative to the first and second portions such that, when a voltage is applied between the positive and negative electrode terminals, a size of the dielectric polymer roll increases and provides a displacement of the second portion with respect to the first portion.
