Design of a Vagus Nerve Stimulator with Parallel Spiral Coils and Switching-Controlled WPT

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, a vagus nerve stimulation system is proposed that generates stimulation pulses by controlling the power transmission switching circuit according to the required stimulation duty ratio. The generated waveform is wirelessly transmitted and rectified to produce stimulation pulses. This enables a simplified power-receiving circuit consisting of a receiving coil, a matching circuit, and a rectifier. To ensure sufficient received power in the presence of transmission losses and coil misalignment, a high-Q parallel coil is adopted to achieve high WPT efficiency. Experimental results demonstrate a 22.2-persentage-point improvement in maximum available power transfer efficiency compared with a conventional coil. Furthermore, WPT experiments through porcine skin demonstrate the generation of 2.5 mA stimulation pulses.
