Injectable Wireless Neurostimulator
Draper Lab (Cambridge, MA) announced late last year that its engineers had developed an injectable neurostimulator, coated with epoxy, which was small enough to be injected and clipped to a peripheral nerve. As this piece says “The device is 2.5 millimeters long with wires 0.5 millimeters in diameter, making it five times smaller than other radio-powered wireless stimulators. It consists of a coil to receive power, a capacitor to tune the resonant frequency of the receiver and a diode to rectify the radio-frequency signal to produce neural stimulation.” While this was only demonstrated in lab animals, the proof of concept was significant enough for future applications to control chronic pain, incontinence, hypertension, Parkinson’s disease and epilepsy.
