POWER GENERATION ELEMENT AND METHOD FOR MANUFACTURING POWER GENERATION ELEMENT

WIPO Patent Application WO/2020/204069

A1

A power generation element (1) is provided with: a polymer fiber body (FB) formed by three-dimensionally depositing electrically chargeable non-piezoelectric polymer fibers; electrodes (121, 122); and a holding member (11). The polymer fiber body (FB), when divided by a single virtual plane (VPL), has more positive charges than negative charges disproportionately on one side and has more negative charges than positive charges disproportionately on the other side. The holding member (11) holds the electrodes (121, 122) in a state in which the distance between the electrodes (121, 122) can be varied. The polymer fiber body (FB) is interposed between the electrodes (121, 122). The holding member (11) may take a first state in which the electrode (121) is spaced apart from the polymer fiber body (FB), and a second state in which the electrode (121) is in contact with the polymer fiber body (FB).
