A low-power wireless sensor/actuator network was specially developed and optimized for piezoceramic transducer-based active\nsensing applications. Wireless sensor network promises increased system flexibility, lower system cost, and increased robustness\nthrough decentralization. Piezoceramic signal conditioning circuit, actuating circuit, power management, and wireless\nmicro controller were integrated in the hardware design. IEEE 802.15.4 wireless stack protocol was implemented on the\nhardware, and user input/output management together with a shell provided easier debugging and configuring interface. The\ndesigned system provides a low-power wireless solution towards many applications such as wireless structural health monitoring\nand wireless structural vibration control.
