摘要

The present invention relates to a manufacturing method of a micro-piezo-electric flexible wire which can obtain piezoelectric energy with good efficiency against externally applied load and is resistant to brittleness, a piezoelectric energy harvester using the micro-piezoelectric flexible wire and a method of manufacturing the piezoelectric energy harvester . A method of manufacturing a microfiamagnetic flexible wire according to the present invention includes the steps of forming an active layer 112 in which a ceramic-polymer material is coated on a surface of a metal wire 111 to form an active layer 112, A conductive layer forming step S140 for forming a conductive layer 114 by applying a metal to a surface of the active layer 112; And a polarization inducing step (S150) of applying an electric field to the metal wire (111) and the conductive layer (114) to cause polarization in the active layer (112), wherein the piezoelectric energy harvester A step S210 of arranging the wires 110 orthogonal to each other or arranging them in the same direction, a polymer molding step S220 molding the flexible polyelectrolytes between the micro-piezoelectric flexible wires 110, And an output electrode installation step (S230) of providing an output electrode (130) electrically connected to the metal wire (111) and the conductive layer (114) inside the flexible piezoelectric flexible wire (110) .
