Wireless system powers devices inside the body
Massachusetts Institute of Technology researchers and Brigham and Women’s Hospital scientists have developed a wireless, ingestible system that can power and communicate with devices that are implanted deep within the body. The researchers suggest that the system could be used to deliver drugs, monitor conditions inside the body or treat diseases by stimulating the brain with electricity or light.The implants are powered by radio frequency waves that can safely pass through human tissue. The waves are able to power devices that are 10 cm deep in tissue from 1 meter away.
Since the devices don’t need a battery, they can be made tiny. The researchers tested a prototype that was about the size of a grain of rice, but they hope to make the devices smaller in the future.
