Currently, problem of battery life is restricting the development of almost all of the wireless sensor networks, especially in structural health monitoring. This paper proposes and proves the possibility of a continuous battery life solution for wireless sensor networks using wireless power transfer. Different from current mainstream methods using resonance coils, this research is using 950MHz electric waves for power transfer. Experiment results shows that this power transfer system is able to support sensor modules operation at 10m distance under current structure monitoring plan. Also, this system is able to recharge batteries at 16m distance maximum.
