Abstract
This paper describes the results of development of a plasticization PVC gel added the high-permittivity powder of polyaniline coated oxide polymer on surface. The displacement and force of gel actuator are higher than a pure gel, since the composite gel has high-permittivity and low Young's modulus. The dielectric constant and Young's modulus of fabricated gel added polymer powder were 25 and 0.28 MPa, respectively. The amplitude actuator using the composite gel was 38 μm when the frequency of applied vibration was 200 Hz. The result of sensory evaluation using the trial Braille display was that a perceivable frequency was 300 Hz. To the question of which of two vibration is fine, all test subject were selected the actuator using composite gel.
