Researchers from Japan’s National Institute of Advanced Industrial Science and Technology (AIST) have developed a micromotor device powered by bacteria. The devices are likely to be very helpful in the medical arena. The 20 micron (1 micron = 1 millionth of a meter) diameter revolving motor has a 13-micron diameter groove etched into a silicon substrate. The surfaces of the feet and the groove are treated with proteins that cause the bacteria (introduced through a connected groove) to move in one direction, spinning the motor as they pass through.

AIST of Japan also created real 3D images using laser plasma.
