Sensors Without Batteries
Thursday, October 18th, 2007Wireless battery-powered sensors that monitor bridges and report changes (that may lead to failure) are easy to install, but it is unwieldy to provide power for the sensors. Each bridge needs at least several sensors, many installed in hard-to-access locations. Replacing millions of batteries could become a problem, adding to the expense of maintaining the bridges. The Clarkson researchers have found a way around this problem and have “completely eliminated battery from the equation”. More information here and here.
