▎ 摘　　要

NOVELTY - Sound-controlled extrusion-type power generation thin film has a metal stainless steel plate, a silver metal electrode (I), a graphene conductive thin film (I), a first zinc oxide nanowire, a polyvinylidene fluoride piezoelectric thin film, a second zinc oxide nanowire, a graphene conductive film (II) and a metal silver electrode (II). USE - Sound-controlled extrusion-type power generation thin film is useful in superconductor for power generation. ADVANTAGE - The extrusion-type thin film has low sound generation rate, and is easy to export. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of sound-controlled extrusion-type power generation thin film.
