Powering Brain Implants with Radio Waves
August 28, 2018 | Terry Sharrer
“Scientists at MIT have developed a wireless system that can power tiny implantable devices in the body, without the need for batteries. The system relies on radiofrequency waves emitted by an antenna outside the body, which can then power the implants from as far away as one meter and as deep as 10 cm below the body surface. At present, the devices are as small as a grain of rice, but because they do not require a battery, the researchers believe that they could be miniaturized further. The system could provide power for a variety of implantable sensors and drug delivery devices. MORE WITH VIDEO
