Abstract

This paper presents a new use of piezoelectric PVDF film as an event-driven sensor switch that activates the power-management circuit for a subsequent wireless sensor ZigBee such that it would not consume extra power during the sleep mode. The circuit is designed to pick up a mechanical vibration with the PVDF film and control the self-holding circuit to keep flowing the drive current to the load until a reset pulse signal is received. The developed power management circuit can supply load current upwards of 33 mA at 3.3 Vdc for load resistance ranging between 100 Ω and 1 MΩ.
