Injectable Radios to Broadcast From Inside the Body – IEEE Spectrum

Implantable medical devices usually have to trade smarts for size.

The hardest thing to shrink isn’t the processor. It’s actually the radio, says Blaauw.

Last week at the IEEE International Solid-State Circuits Conference in San Francisco, Blaauw and fellow engineers David Wentzloff and Yao Shi showed a prototype injectable radio with a volume of just 10 cubic millimeters (1 mm x 1 mm x 10 mm) that can send powerful radio signals 50 centimeters away, including through 3 centimeters of tissue.
