The world's smallest computer - Michigan Micro Mote - So Tiny!

Tiny Computure - Michigan Micro Mote (M^3)

Computers used to consume whole rooms, but now one computer can fit on the edge of a nickel. At just one millimeter cubed, the Michigan Micro Mote (M^3) is believed to be the smallest autonomous computer in the world.

For over a decade, the faculty and students at the University of Michigan's computer science department have been working on the M^3. As the Internet of Things (IoT) gets bigger, the Michigan team is pushing to make computers ever smaller.

Despite its tiny size, the M^3 has the ability to take pictures, read temperatures and record pressure readings. Researchers hope to implement the microcomputer into a variety of applications ranging from medical to industrial.

With no space for a keyboard, mouse or display, the faculty and students had to invent a different way to communicate with the Micro Mote. The M^3 is programmed and charged via light. By strobing light at a high frequency, the operator is able to send information to the computer. Once the Micro Mote processes the data, it is able to send the information to a central computer via conventional radio frequencies.

The M^3 is ready for production now, and the faculty and staff are already looking forward to creating even smaller computers, which they call smart dust.

Hardwares are vanishing into the air and we suppose to live in the future already.
Some dangerous thought suddenly comes to mind as soon as this tiny computer.
It seems to be possible to jump off internet of things and reached to human's body like we've seen in SF movie. The world human is controlled by invisible computer, is it scary?
