University of Michigan‘s scientists should be proud to their latest invention for the world’s smallest solar sensor. The solar sensor has a dimension of 2.5mm x 3.5mm x 1mm and it has an ARM Cortex M3 processor. It uses about 2,000x less power in sleep mode compared to products currently available. It could be used in several applications, including being embedded in your body and running off your body heat.

The dimension is said to be 1,000 times smaller than current solar sensors available in the market. The solar sensor could run indefinitely, the power used is about one billionth of a watt and it uses about half a volt to operate and has a built in Cymbet battery that can output up to four watts.’

We should expect a further reduction on current mobile computer’s dimension in the very near future! Bravo for University of Michigan!
