报告摘要:

Low-power communication devices like sensors have been applied in a wide range of sensing and monitoring applications. However, sustainable monitoring service is hindered due to the requirement of frequent replacement of depleted batteries. Fortunately, with advancement of low-power electronics, continuously reduced power requirement of a single node brings self-powered or ‘perpetually powered’ systems from concept to practice. Energy harvesting techniques convert available ambient energy into electricity. Wind energy is a potential power source which is ubiquitous in both indoor and outdoor environments. By pursuing aeroelastic instabilities, the wind-induced vibration energy can be converted to electricity via different transduction mechanisms. The focus here is to develop advanced techniques for small-scale wind energy harvesting with piezoelectric transduction. The recent progresses in small-scale wind energy harvesting research will be discussed, including the design of novel wind power harvesting structures based on aeroelasticities, the development of aero-electro-mechanically coupled system models and derivation and analytical solutions for system responses, and the efficiency enhancement through two aspects: structural modifcation and interface circuit improvement.
