Effect of Different Elastic Systems on Cantilever Beam Energy Harvester

In order to analyze carefully the effect of elastic system on force-electric performance, the finite element model of elastic cantilever beam energy harvester was obtained through meshing the corresponding solid model and then used to simulate. Simulated results show that the more parallel elastic system can achieve the larger output voltage, power and the narrower frequency band and the smaller acceleration, and the more serial elastic system can achieve the smaller output voltage and power, the wider frequency band and the larger acceleration.
