▎ 摘　　要

NOVELTY - A fibrous-type energy harvester consists of an electrode (e1) comprising conductive fibers (c1) and a polymer electrolyte (a1), an electrode (e2) comprising conductive fibers (c2) and a polymer electrolyte (a2), and a hydrophilic polymer coated on at least one of electrodes (e1) and (e2) and electrically insulating the electrodes (e1) and (e2). The polymer electrolyte (a1) comprises at least one selected from the group consisting of a polymer electrolyte coated on the conductive fiber (c1), and a polymer electrolyte impregnated inside the conductive fiber (c1). The polymer electrolyte (a2) comprises at least one selected from the group consisting of a polymer electrolyte coated on the conductive fiber (c2) and a polymer electrolyte impregnated inside the conductive fiber (c2). The electrodes (e1) and the electrode (e2) face each other and are optionally twisted. The polymer electrolyte (a1) is different from the polymer electrolyte (a2). USE - Fibrous-type energy harvester used for wearable electronic device e.g. humidity sensor for detecting humidity, and respiration sensor for sensing inhalation and exhalation (all claimed). ADVANTAGE - The harvester is sensitively responding to humidity by using the electrode prepared by coating the polymer electrolyte on the conductive fiber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the fiber-type energy harvester.
