Nerve Stimulator Can Be Implanted Deep in the Body

Nerve Stimulator Can Be Implanted Deep in the Body
Apr-04-18
A new, minimally invasive ultrasound-powered nerve implant could allow for vagus nerve stimulation deep inside the body.

Developed by a team from Stanford University, the biocompatible implant is about the size of a grain of rice, but holds all the necessary electronics, including a pair of stimulating electrodes, piezoelectric receiver that converts the ultrasound to electricity, and a custom controlling chip. The chip can be implanted with minimally invasive surgery, and the stimulation’s amplitude, pulse width and frequency can be adjusted according to the needs of the patient’s peripheral nerves.
