BPN562: AC Energy Scavenging for Smart Grid Sensing

Project ID BPN562
Start Date Thu 2010-Feb-04 10:39:45
Last Updated Wed 2014-Aug-13 10:44:15
Abstract The goal of this project is to devise small, inexpensive modules for indoor or outdoor deployment that sense electrical variables on, and scavenge energy from, energized conductors such as appliance cords and the conductors on high-voltage power transmission lines and equipment. In addition to an energy scavenging element, the modules will contain sensors, their associated signal conditioning circuitry, power conditioning and storage elements, and a wireless radio and antenna. We have recently demonstrated the ability to scavenge 2mW from a nearby conductor carrying 20 Arms, which is 10-100x more than can be extracted using comparable coil-based approaches.
