This paper proposes a method of wireless feeding for an electrostatic haptic display which consists of multiple contact pads and a non-segmented electrode. We have developed a multi-user haptic display that provides haptic feedback with electrostatic friction modulation by applying voltage between multiple contact pads and a non-segmented base electrode. The display requires feeding wire for each contact pad, which impairs its operability. For this technical challenge, this work investigates use of the base electrode as a transmitter electrode of wireless feeding. To facilitate that, the electrode of the pad is split and connected with a coil so that resonance current runs and boosts the voltage between the pad and the base electrode. Experiments with a prototype demonstrate its robustness to alignment of pad position and its possibility of multi-pad feeding with frequency division.
