Abstract
The present invention relates to a method and a device for converting energy using a change of a contact area and a contact angle of liquid and, more specifically, to a method and a device for converting mechanical energy into electric energy by applying a reciprocal phenomenon of electrowetting, wherein liquid and gas are positioned between two facing substrates and energy is converted by using a volume change of a fluid, such that the present invention has the advantages of preventing channel-blocking without requiring all facing electrodes to be patterned, simplifying a device configuration, implementing easy control, and removing the need to apply an external power source.
