- •
The quad-stable energy harvester has a wider range of frequencies under low level excitations.
- •
The quad-stable configuration can easily attain snap-through oscillations under random excitations.
- •
The quad-stable energy harvester can produce higher output voltage and improve the harvesting efficiency dramatically compared with the traditional bi-stable energy harvester.
