Piezoelectric film electricity generator and manufacture method thereof

The invention belongs to the technical field of new energy, and particularly relates to a piezoelectric film electricity generator and a manufacture method thereof. The piezoelectric film energy generator comprises substrates, wherein piezoelectric films are arranged on the substrates; film electrodes are perpendicularly arranged at the two ends of the piezoelectric films respectively; the film electrodes at the two ends of the piezoelectric films are connected to form a closed loop circuit through wires; electric power storing equipment is switched in the closed loop circuit; one sides of the substrates are connected with an external power mechanism; the external power mechanism provides mechanical energy for the substrates; the piezoelectric films are produced by being printed or coated with metal ink with low melting point on the substrates. According to the invention, the affiliation character of the metal ink with low melting point and the surfaces of the substrates is utilized, the piezoelectric electricity generator for capturing kinetic energy is produced through a printing or coating manner; the surfaces of the substrates such as clothes, building walls, doors and windows and advertising boards can be directly printed or coated; the production process can be finished under a normal condition, the requirements on the environment are reduced, and large-scale popularization and application of the piezoelectric film electricity generator can be realized.
