(c) Comparison of open-circuit voltages from main beam and secondary beam of proposed 2DOF harvester [40] cutting out a secondary beam inside the main beam. Compared to the conventional SDOF harvester, this device was able to generate two close effective peaks in voltage response with properly selected parameters, as shown in Fig. 20b. Thus, multimodal energy harvesting was achieved with only a slight increase of the system volume.

However, for small excitation amplitude, actuation energy is required to perturb the beam and hence drive the system into high-energy orbits, which was not addressed. 50 L. Tang et al. Fig. 2 Stochastic Forcing For a bistable system, stochastic forcing can also induce transitions between the stable equilibria of the system, and thus causing large-amplitude oscillations. Cottone et al. [61] realized a piezoelectric inverted pendulum by using the bistable mechanism (polar opposing magnets with a small separation distance ).

However, how to avoid mode-shape-dependent voltage cancelation was a critical issue. For the three piezoelectric segments combined in series, 36 L. Tang et al.
