Nonlinear characteristics of bistable oscillators can be exploited to increase bandwidth of energy harvesting devices. Electromagnetic energy conversion has the advantages of high current and high power output for vibratory energy harvesting. In this thesis, a compliant bistable mechanism (BM) for wideband vibratory energy harvesting is developed. The BM has one unstable and two stable equilibrium positions. When the amplitude and/or frequency of an external excitation reach certain threshold values, the BM exhibits snap-through behaviors, typically seen in bistable systems. The oscillator with snap-through phenomenon has larger vibration amplitude and thus induces more electrical energy through the electromagnetic conversion than its linear mono-stable counterpart. Finite element analyses are adopted to obtain the force-displacement relation of the BM. An analytical model is developed to calculate the time response and frequency response of the electromagnetic energy harvester. Experiments are carried out to validate the efficiency of energy harvesting device with the nonlinear bistable oscillator.
