Title:
IONIC HYDROGEL-BASED ENERGY HARVESTER
Document Type and Number:
WIPO Patent Application WO/2023/075047
Kind Code:
A1
Abstract:
The present invention relates to a polymer hydrogel-based ion energy harvester, which is designed to harvest low-frequency mechanical vibrations by using slow diffusion of ions, as an alternative to a conventional energy harvesting technique based on electron transfer or electron conduction. The ionic hydrogel-based energy harvester according to the present invention has very superior advantages compared with existing methods in terms of extracted current density, manufacturing cost, manufacturing method, and the like, by manufacturing energy elements through simple stacking of polymer hydrogels.
