Rainwater- and air-driven 40 mm bladeless electromagnetic energy harvester
A 40 mm electromagnetic energy harvester driven by both rainwater and air is designed and experimentally tested. Its performance is first assessed by measuring the system response for 4 different levels of air flow excitations. It shows that about 0.5 W power is generated. Parametric analysis is the...
