Massachusetts Institute of Technology researchers, working with colleagues at Brigham and Women's Hospital in Boston, have developed a wireless method for powering and communicating with devices implanted within the human body.
During testing in animals, the researchers demonstrated that the implants can be powered by radio frequency waves from up to one meter away, when the device is implanted 10 centimeters deep in tissue.
The researchers tested a prototype device about the size of a grain of rice, and they theorize it could be made even smaller.
The implant relies on In Vivo Networking, a system the researchers devised that uses an array of antennae that emit radio waves of slightly different frequencies; when the high points of the waves overlap, they provide energy to power the implanted sensors.
The researchers will present their work at the ACM Special Interest Group on Data Communication conference (SIGCOMM 2018) in August in Bupadest, Hungary.
