Abstract :
This paper presents a nonlinear energy harvester that can be operated in a wide frequency range of tens of Hz, as a potential power supply for tire pressure monitoring systems (TPMS). Frequency up-conversion is achieved by a two-stage oscillator structure. The non-contact magnetic repulsive driving mechanism eliminates mechanical collision during operation, thereby improving efficiency and endurance. A miniature energy harvester has been designed, fabricated and characterized, resulting in a generation capability of over 10μW of average power within the frequency range of 10Hz to 22Hz (under 1g acceleration).
