Method and system for harvesting energy using an EAP based deformable body

Rick van Kessel (Inventor)

Research output: Patent

Abstract

The EAP based deformable body is an elastically deformable body including an arrangement of stretchable synthetic material and electrodes being arranged as a variable capacitor with a capacitance that varies as the deformable body stretches and relaxes. The method includes :looping through an energy harvesting cycle with a) stretching the deformable body from a minimal relaxed size L1 to a maximal stretched size L2; b) at the maximal stretched size electrically charging of the variable capacitor to create an electric field over the capacitor with an upper electric field level value; and subsequently c) a relaxation step from maximal stretched size to the minimal relaxed size; d) at the minimal relaxed size of the deformable body, electrically discharging the capacitor to a minimal charge level and a minimal electric field level value.
