A thin-film lead zirconate titanate, Pb(Zr,Ti)03, MEMS Piezoelectric Micro Power Generator (PMPG) has been integrated with a commercial wireless sensor node (Telos), to demonstrate a self-powered RF temperature sensor module. PMPG and a power management module are designed to satisfy sensor node's power requirement. An electro-mechanical model of PMPG has been developed to maximize power output. The 2nd generation PMPG is designed to provide 0.173 mW power at 3 V DC with a natural frequency of 155.5 Hz. The power management module is developed to provide AC-DC rectification, energy storage, and active switching between PMPG and application circuit. To minimize power consumption, sensor data is taken at a discontinuous interval. A test bed is developed, which mimics that of a liquid gas pipeline used in the Alaska, where the self-powered sensor be used to monitor pipeline temperature.
