This research introduces novel recharging systems and algorithms to supplement existing systems and lead to autonomous, sustainable energy management on sensor networks. The purpose of this project is to develop a wireless power transfer system that enables unmanned areal vehicles (UAVs) to provide power to, and recharge batteries of wireless sensors and other electronics far removed from the electric grid. We do this using wireless power transfer through the use of strongly coupled resonances. We have designed and built a custom power transfer and receiving system that is optimized for use on UAVs. We are investigating systems and control algorithms to optimize the power transfer from the UAV to the remote sensor node. In addition, we are investigating energy usage algorithms to optimize the use of the power in networks of sensors that are able to be recharged wirelessly from UAVs.
This research is funded in part by the National Science Foundation under grant numbers CNS-1217400 and CNS-1217428.
