The paper discusses a novel method for nonlinear energy harvesting, which leverages the dynamic properties of stochastic nonlinear oscillators to outperform traditional linear oscillators in ambient vibration energy harvesting. The authors propose using a bistable oscillator, specifically a piezoelectric inverted pendulum with a tip magnet, to convert mechanical vibrations into electrical energy. By adjusting the distance between the external and tip magnets, the pendulum can exhibit different dynamical behaviors, including linear and nonlinear oscillations. The study demonstrates that the nonlinear oscillator can achieve significantly higher power output compared to linear oscillators, especially under wide-spectrum vibrations. The performance is quantified through experimental results and a theoretical model, showing a potential gain of 400% to 600% in energy harvesting compared to standard linear oscillators. The findings suggest that this approach could be applicable to micro/nano-scale power generators and has broad implications for ambient energy harvesting.The paper discusses a novel method for nonlinear energy harvesting, which leverages the dynamic properties of stochastic nonlinear oscillators to outperform traditional linear oscillators in ambient vibration energy harvesting.
