God Bless Michigan

The good stuff just keeps on coming: teeny, tiny & with possible medical applications.

A tiny, tiny solar-powered sensor system is in the works.
Developed at the University of Michigan, the 2.5 x 3.5 x 1 millimeter system is the smallest in the world, and it can harvest energy from its surroundings almost perpetually.

Measuring in at 9 cubic millimeters, the micro sensor requires half a volt to operate, but the device can put out up to 4 volts of power with reasonable indoor lighting. It probably won’t be on store shelves any time soon, but the solar-powered system could be used to make environmental sensor networks that keep track of water and air quality both cheaper and more efficient. The device also has a number of possible medical applications — for example, it could monitor pressure changes in the eyes for patients with glaucoma. Eventually, the sensor could be powered by heat or movement and used inside the body.
