This Is The Smallest Computer Ever

Millimeter-Scale Computer

Greg Chen

Tiny-fingered researchers at the University of Michigan have created this computer, the world's first complete millimeter-scale computing system. It is a prototype designed to be implanted in a human eye, to monitor internal pressure there for signs of glaucoma.

The machine includes a teeny battery, a consolidated radio and antenna, a pressure sensor, memory, and a rather diminutive processor designed to consume extremely little power.
