[center]world Most Smallest computer[/center]

Not to be outdone by the “world smallest computer” IBM revealed in March, a team at the University of Michigan is calling IBM’s bluff with an even smaller computer that’s “dwarfed by a grain of rice,” measuring just 0.33mm on each side. The university originally held the “world’s smallest” trophy with its 2mm x 2mm x 4mm Michigan Micro Mote until IBM’s smaller-than-salt 1mm x 1mm computer entered the scene earlier this year.
Although the word “computer” brings an image of a miniaturized PC sitting on the tip of your finger, the Michigan team now questions the term. When you power off a desktop or laptop, all the programs and data still reside on the device’s internal storage. Boot up the device and all your cat videos, games, documents reappear. That can’t be said with these “computers” created by IBM and the Michigan team.

The team’s new “computer” uses photovoltaic’s, a method of converting light into electricity. It also consists of a processor, system memory, and wireless transmitters and receivers that send and receive data through light. Rounding out the package is a base station that feeds the computer with light for power and programming. The station also receives all data transmissions.
Currently, the tiny computer serves as a precision temperature sensor. It uses electronic pulses to convert temperatures into timed intervals. The result, for example, is the ability to report temperatures in a cluster of cells within a tumor with an error rate of around 0.1 degrees Celsius.
