Image 1 - Insects Could Help Find Disaster Survivors
2011-12-26 08:11:50

Insects outfitted with tiny cameras and microphones could be used to help find survivors of earthquakes and other disasters during search and rescue operations, scientists have said. The device will be powered by the insect themselves as they move. By converting kinetic energy into electricity, the devices could have a lasting power source. The device could also harness electricity from heat given off as well. The idea is that once these insects, particularly beetles, are fitted with...

Tiny generators developed at the University of Michigan could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor. The energy-harvesting devices, created at U-M's Engineering Research Center for Wireless Integrated Microsystems, are highly efficient at providing renewable electrical power from arbitrary, non-periodic vibrations. This type of vibration is a byproduct of traffic driving on bridges, machinery operating in factories and...
