Hybrid Mode Wireless Power Transfer for Wireless Sensor Network

Wireless sensor network will find more applications in spacecraft. To power wireless sensors with varied energy requirement, hybrid mode wireless power transmission scheme is proposed in this paper. For sensors of 10 W power dissipation, resonance-based wireless power transfer is employed. For those of a few mW to a few hundreds mW power dissipation, microwave power transmission is recommended and for those of 100 uW or less, microwave power harvesting is suggested. This ensemble can support almost all sensors and act as a baseline for similar applications.
