Abstract :
A battery-less tire pressure monitoring system (TPMS) with piezoceramics mode energy harvesting is presented. A chip of power recovery circuit at piezoceramics mode is designed and implemented at Chartered 0.35 ¿m high voltage CMOS process. Based on testing results, with the piezoceramics, the chip converts mechanical strain energy to DC power which provides stable voltage output around 3 V, and about 10 mA current for almost 20 ms at recurring working mode for sensor, MCU and data transmitter to work well in a tire monitoring module of TPMS. And taking the frequency multiplication method mentioned last, the application of this type of battery-less TPMS in real car environment is hopeful.
