Abstract

This paper introduced a wireless power transfer system controlled by a microchip board. Recently, wireless sensor network for structure health monitoring has been developed. However, battery consumption became an important problem, especially in structure health monitoring system, since maintenance costs huge human resources. Therefore, a wireless power transfer system is developed to supply sensor networks. This system works at 950MHz band, and the transmission rate is about -8dBm (about 140μW) at 10m's distance. After boost converter, power efficiency became 33%, which means there is less than 50μW can be stored into batteries. Moreover, a microchip board is used in this system to control and coordinate the whole transmission system, including the wireless modules. Comparing with power consumption of current microchip, 50μW is not enough. Therefore, power consumption control method is developed in this system.
