Abstract
The present invention relates to an energy conversion device using a change of a contact surface with liquid and, more specifically, to a method and a device for converting mechanical energy into electrical energy by applying an opposite phenomenon to an electrowetting phenomenon. The energy conversion device having a simplified structure and reduced manufacturing costs with minimal malfunctions by changing a contact surface with liquid between a pair of electrodes and using the change of the contact surface with the liquid to generate electrical energy such that channel blocking can be prevented or a lubricating layer or electrodes complicatedly patterned on a channel are not required.
