- •
The electromechanical equations are established to characterize the quad-stable energy harvester.
- •
The quad-stable configuration can easily attain snap-through oscillations.
- •
The quad-stable energy harvester has a wider effective frequency band and improves the harvesting efficiency dramatically compared with the traditional bi-stable energy harvester.
