APPARATUS FOR ENERGY HARVESTING USING CHANGE OF WETTING ANGLE AND CONTACT AREA OF LIQUID

摘要

The present invention relates to a device and an energy conversion method using the change of a contact angle and a contact area with liquid and more specifically, to a device and a method of converting mechanical energy to electrical energy by applying the opposite phenomenon of electrowetting phenomenon. The present invention places gas or liquid between two substrates that are opposite each other and prevents a channel clogging phenomenon by converting energy using the amount change of liquid. The energy conversion device has the advantage that it can simplify device constitution since it is unnecessary to pattern all electrodes opposing each other, easy to control and the insertion of an external power is not necessary.
