Ambient energy harvesting has been in recent years the recurring object of a number of research efforts aimed at providing an autonomous solution to the powering of small-scale electronic mobile devices. Among the different solutions, vibration energy harvesting has played a major role due to the almost universal presence of mechanical vibrations. Here we propose a new method based on the exploitation of the dynamical features of stochastic nonlinear oscillators. Such a method is shown to outperform standard linear oscillators and to overcome some of the most severe limitations of present approaches. We demonstrate the superior performances of this method by applying it to piezoelectric energy harvesting from ambient vibration.
近年来，环境能量收集一直是众多研究工作反复关注的对象，旨在为小型电子移动设备的供电提供自主解决方案。在各种不同的解决方案中，振动能量收集发挥了主要作用，这是因为机械振动几乎普遍存在。在此，我们提出一种基于利用随机非线性振荡器动力学特性的新方法。结果表明，这种方法优于标准线性振荡器，并克服了现有方法的一些最严重限制。我们通过将该方法应用于从环境振动中进行压电能量收集，证明了其卓越性能。
