Abstract
A method and device for gasflow, e.g. airflow, energy harvesting is disclosed. In one aspect, the device includes a cavity resonator such as a Helmholtz resonator which has a membrane for converting gasflow in vibration. The device may further include a vibrational energy harvester for converting the converted vibration into electrical energy. The device for gasflow energy harvesting is adapted such that the movement of the vibrational energy harvester is decoupled from the movement of the membrane. This allows to obtain a good output power of e.g. more than about 10 μW.
