The present invention relates to an energy conversion device using a 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 contact surface with liquid is being changed within a pair of electrodes, and the resulting change in the contact surface with liquid is being utilized for generating electrical energy. The device can be simplified and the manufacturing cost thereof is being reduced, furthermore it is effective in implementing an energy conversion device that is less faulty, by preventing channel blocking phenomenon and not requiring a lubricating layer or an electrode complicatedly patterned on a channel. Besides, it is advantageous in that a flexible device can be realized and a large area application is facilitated by simplifying the device structure.
