With the wide application of small electronic devices such as wireless sensor networks and intelligent detection systems, the low power threshold of electronic devices makes it possible to capture the weak energy of the environment and realize the self powered application of devices. As a potential innovation, energy collection technology provides power for the next generation of human technology in the information age.
Recently, Applied physics Letters, an international top natural index journal in the field of physics, published a research paper entitled "An enhanced galloping based piezoelectric energy collector with non rotating bluff body", which proposed a piezoelectric wind energy collector (BNRGH) based on non rotating galloping of blunt bodies. This structure can effectively prevent the change of attack angle caused by the self rotation of the blunt surface, avoid the amplitude saturation of the bluff body under high wind speed, and improve the overall output efficiency. It has great application potential in the fields of intelligent electronics, health monitoring, wireless self powered node network, etc.
