This tiny computer is said to be the world's smallest, and is designed for implantation inside the eye of a glaucoma patient.
Shown sitting on the edge of a penny, the computer measures just over 1-millimeter cubed, or considerably smaller than the head of a typical pin. It's pretty well equipped too, with a built in pressure sensor, memory, radio transmitter, antenna, and a thin film battery that is recharged by a tiny solar panel.
One implanted, the computer makes regular pressure measurements inside the eye and stores the results in its memory. To download the stored data, an external device is held near the eye to receive the signal from the radio transmitter.
Developed by researchers at the University of Michigan, the computer is still a few years from actual patient trials.
