When a high voltage is applied to the interdigitated electrode pattern, an electric field is formed causing partial polarization on the surface of the polymer thin film. This phenomena causes polarization of target’s surface to be grasped referred to as an electrical adhesion force. In order to improve the electrical adhesion, it is necessary to improve the dielectric constant, close gap between the electrode patterns and the surface condition. In this study, we aimed to obtain high dielectric constant by dispersing inorganic particles with high dielectric constant in stretchable polymer. Inorganic particles with nano-sized tend to aggregate due to their high surface area, which may result in a lower dielectric constant. In order to overcome this, optimization of dispersion was carried out by applying dispersion method according to viscosity. Finally, we succeeded in lifting an object by making a gripper with electrical adhesion film. |
