Paper sheet separating mechanism as in copy machine, printer, and ATM have employed frictional force of rubbers, however, multi-feeding of papers is inevitable due to aging deterioration, e.g. wear and hardening of the rubbers. To prevent the multi-feeding in paper sheet separating mechanisms, we have developed electroadhesion pads that can generate large electroadhesion force at low voltage without any deterioration over time. Here, to optimize the electrode shape of the electroadhesion pad, electroadhesion forces were theoretically and experimentally examined with changing electrode width and gap amount of the electroadhesion pads. The theoretical calculation of the electroadhesion forces was made with a formula derived from Coulomb’s law. The experimental results qualitatively agreed with the theoretical calculation and the maximum electroadhesion force was obtained with the electrode width of 5 mm and the gap amount of 1 mm. These results give helpful information to configure the electroadhesion pad, and also suggest the feasibility of the paper sheet separating mechanism with electroadhesion force instead of using frictional force of rubber.
