Title:
HUMIDITY-RESPONSIVE ENERGY HARVESTER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/119307
Kind Code:
A1
Abstract:
Provided is a humidity-responsive energy harvester. The humidity-responsive energy harvester may comprise: a substrate structure comprising carbon fibers; a first harvesting structure disposed on the substrate structure and comprising a polymer with the concentration of hydrogen ions changed in response to humidity; and a second harvesting structure disposed on the first harvesting structure and comprising a carbon fiber coated with active materials including a composite of a transition metal and an oxide of the transition metal, wherein the polymer of the first harvesting structure has a changed concentration of hydrogen ions in response to humidity and thus causes a difference in redox reaction in the second harvesting structure, leading to energy generation.
