概要

• 論文の詳細を見る

• A wind-energy-harvesting device utilizing the principle of a harmonica was created. A reed in a resonant cavity vibrated efficiently with the blowing wind, and a piezoelectric element stuck on the reed generated electricity. The dimensions of the wind inlet were approximately $30\times 20$ mm2. The device was investigated with a wind speed ranging from 2.8 to 10 m/s. An output power of 0.5–4.5 mW was obtained with a matching load of 0.46 M$\Omega$. The energy conversion efficiency of the device could reach up to 2.4%.
