Abstract

Electrical stimulation of the neuromuscular system holds promise for scientific and therapeutic biomedical applications. A key challenge is supplying power chronically, especially for high voltages/currents. Wireless systems offer a solution but currently lack the power and voltage for applications like muscle stimulation. This paper introduces a passive resonator-optimized power transfer design enabling ±20 V and >300 mW at 0.2 cm², a 500% improvement. Multichannel, biphasic, current-controlled operation is demonstrated in freely behaving animals, with chronic results showing functionality over 6 weeks in rats, enabling fine control of spinal and muscle stimulation.
