报告内容摘要：

Vibrations usually cause troubles and are aimed to be suppressed. However, the fast advancing low-power wireless sensors in internet of things applications bring the opportunities of utilizing vibrations as sustainable power sources. In this talk, I will briefly overview some recent efforts of my group in harvesting energy from low-frequency and broadband vibration sources by toy-inspired designs of harvesters, nonlinear mechanisms and self-adaptive tuning strategies. In addition, small-scale wind energy can also be harvested by leveraging the aerodynamic instability induced vibrations, which, however works typically for a specific wind direction. In this talk, I will also overview some recent progress in developing multi-directional and multi-modal wind energy harvesters through a novel beam structural design.
