Clarkson Researcher Harvest Bridge Vibrations for Wireless Sensors
A group of researchers at Clarkson University has developed a method of using bridge vibrations to power wireless sensors. The device uses kinetic energy from the bridge vibrations to generate AC current, the converts it to DC voltage and stores it until enough power is available to take a measurement and transmit the signal to a nearby PC. The group has developed a hardware platform called an AmbioMote which makes the most use of this free, wireless electricity. This technology could be used to instrument many structures for decades without the expense and environmental impact of battery replacement. The AmbioMote is in production for commercial use and will be available on December 25.
