In this paper, a wireless power charger with dynamic pivoting antenna module based on electromagnetic coupling of coil is proposed for the various wireless sensor systems. The wireless charger consists of two partitions: a cut table soft-substrate power charger circuit and the dynamic and adaptive pivoting antenna module. Wireless sensor system can obtain the power without physical wire connection. Considering the real sensor system implementation environment, the proposed pivoting antenna module can be dynamically adopted and constructed for the suitable size or the number of coil. In addition, by using the proposed cut table soft-substrate power charger circuit, the original wireless sensors can obtain the power with less space.
