The research program aims to study the nonlinear dynamics in vibration-based piezoelectric energy harvesters to achieve wide bandwidth, high power output, small size, and low cost. Vibration-based energy harvesters, capable of scavenging ambient vibrations and converting into electricity, are promising to replace batteries as a main power supply for small autonomous electronic devices. There are two main advantages for such energy harvesters: no replacement and recharging required; no environmental pollution caused by waster batteries. Among different types of vibration-based energy harvesters, piezoelectric energy harvesters (PEHs) are the most promising due to its larger power density.

本课题旨在研究基于振动的压电能量采集器的非线性动力学，以实现宽带宽、高功率输出、小体积和低成本。基于振动的能量采集器能够清除环境振动并将其转化为电能，有望取代电池，成为小型自主电子设备的主要电源。这种能量收集器有两个主要优点：不需要更换和充电；无废电池对环境的污染。在不同类型的基于振动的能量采集器中，压电能量采集器（PEHs）因其更大的功率密度而最有前途。
