Researchers from the MIT Media Lab have developed an antenna — about the size of a fine grain of sand — that can be injected into the body to wirelessly power deep-tissue medical implants, such as pacemakers in cardiac patients and neuromodulators in people suffering from epilepsy or Parkinson’s disease.“This is the next major step in miniaturizing deep-tissue implants,” says Baju Joy, a PhD student in the Media Lab’s Nano-Cybernetic Biotrek research group. “It enables battery-free implants that can be placed with a needle, instead of major surgery.”A paper detailing this…
