MIT engineers build tiny ingestible capsule sensor for internal body temperature
Researchers at MIT, led by Saransh Sharma with senior authors Giovanni Traverso and Anantha Chandrakasan, developed an ingestible capsule that measures body temperature to within 0.01°C. The device runs on a coin-cell battery and uses backscattering to shift most power demands to an external antenna, resulting in what they call the smallest ingestible temperature sensor yet built.
