N2 - A broadband energy harvester using bi-stability and frequency up-conversion is introduced for the first time in a host-parasite shape inspired by the parasitic relationship in plants. A macro-buckled hosting beam is used to create bi-stability by compressing the beam in the axial direction; two piezoelectric micro-beams are amounted on the host beam as parasitic structures to absorb the low-frequency macro-beam kinetic energy and convert it to micro-beams' high-frequency vibration at resonance. The design and operational principle are presented; a prototype was then fabricated and tested. The results illustrate the harvester is capable of harvesting low-amplitude vibration energy over a wide bandwidth at low frequencies. This design provides a potential solution for power supply in self-powered sensing applications in the Internet of Things.
