Pain control on demand based on pulsed radio-frequency stimulation of the dorsal root ganglion using a batteryless implantable CMOS SoC

摘要

Electrical stimulation can effectively control or reduce the sensation of pain. This paper presents the implementation of a batteryless CMOS SoC with low-voltage pulsed radio-frequency (PRF) stimulation. Its effectiveness is demonstrated by observing the behavior of rats receiving localized bi-polar stimulus to the dorsal root ganglion (DRG) of the lumbar nerve without thermal damage.
