Filed: 1992-10-26
Abstract: PURPOSE:To allow precise control while enhancing response by providing a soft and highly elastic polymeric porous member having continuous small holes internally diffused with particles being polarized under function of electric field, and a pair of electrode plates being fixed to sandwich the polymeric porous member. CONSTITUTION:Upon application of voltage of 1500V to an actuator, an electric field E is established between an electrode plate 5, i.e., a positive pole plate 5a, and an electrode plate 6, i.e., a negative pole plate 6b. Consequently, positive and negative charges 31a, 31b in lead titanate zirconate particles 3 are shifted relatively and instantaneously toward the negative and positive pole plate sides 6a, 5a, respectively. In other words, polarization takes place and electrostatic attraction functions between the lead titanate zirconate particles 3 along the electric field E. Consequently, the air is pushed out from small continuous holes 4 thus contracting a polymeric porous member 1 composed of soft polynorbornene rubber 2. When voltage is removed, polarization disappears and the polymeric porous body 1 is recovered to the initial shape.
