New method of wirelessly powering implanted medical devices created

20th May 2014

Future medical technology could be revolutionised following the creation of a new technique for wirelessly powering implanted devices.

A team from Stanford School of Engineering has created an electronic device smaller than a grain of rice that can act as a pacemaker and is powered or recharged wirelessly by holding a power source above the device outside the body.

They were able to do so by designing technology that generated a special type of near-field wave that moves differently through air and biological tissue, allowing it to penetrate to reach deeply-implanted devices without causing damage.

Such an innovation can eliminate the need for bulky batteries and recharging systems when creating pacemakers, nerve stimulators and other sensors or gadgets.

Study co-author and graduate student John Ho said: "With this method, we can safely transmit power to tiny implants in organs like the heart or brain, well beyond the range of current near-field systems."

Numerous researchers are currently trying to develop new ways of improving the usability of medical devices, including through the development of flexible electronic patches that offer comfort and usability benefits.ADNFCR-8000103-ID-801721743-ADNFCR
