Could New Wireless Power Transfer Unleash Electric Medicine?
Stanford University engineers say they have figured out a way to wirelessly send electric power deeper into the body than ever before.
Inventor and electrical engineering assistant professor Ada Poon created a near-field power transmitter like those used to recharge wireless toothbrushes in their cradle. The difference is that hers uses tissue between the transmitter and medical device implanted in the body to amplify the electromagnetic waves. Her team then created an electrode and receiver unit about the size of a grain of rice that can be placed wherever electrical stimulation is required.
