随着技术的发展，设计高效的能源收割机现在是可行的，解决这一需求的一个可行的方法是利用非线性设计的概念和应用。在这封信中，我们对由白泊松噪声模型模拟的随机脉冲激励的线性和非线性压电能量收集进行了比较分析。结果表明，收割机的性能取决于非线性和环境能量的性质，对于给定的环境振动类型，应对非线性进行优化，以实现有效的收获。(C)2011年美国物理研究所。[DOI：10.1063/1.3647556]
Design of an efficient energy harvester is now feasible as technology develops and a viable approach to solve this need is to exploit the concept and application of a nonlinear design. In this letter, we conducted a comparative analysis of linear and nonlinear piezoelectric energy harvesting from random impulsive excitations modelled by white Poisson noise. It is shown that the harvester performance depends on both nonlinearity and properties of ambient energy, and nonlinearity should be optimized for a given type of ambient vibration in order to achieve efficient harvesting.
