Eye implant contains 'world's first' millimeter-scale computing system

Eye implant contains 'world's first' millimeter-scale computing system: "Researchers from the University of Michigan have created what they claim is the world's first millimeter-scale complete computing system, designed as an implantable eye pressure monitor for glaucoma patients. Incorporating a microprocessor, pressure sensor, memory, thin-film battery, solar cell and wireless radio with an antenna that can transmit data to an external reader device, the device is just over one cubic millimeter in size."
