Abstract

The invention discloses a measuring tape type piezoelectric nano generator, which relates to the field of piezoelectric energy conversion, and comprises a shell, a switch, a central shaft, a sleeve, a clockwork spring, a PVDF film, a first piezoelectric electrode layer and a second piezoelectric electrode layer, one side of the shell is provided with an opening, the outer part of one side of the shell is provided with a chute, the chute is located above the opening, and the opening is provided with a through hole. The switch is slidably installed in the sliding groove, and the lower end of the switch can penetrate through the shell to extend into the opening. The PVDF film is wrapped outside the clockwork spring, the central shaft is fixed in the shell, the sleeve is rotatably sleeved on the central shaft, one end of the clockwork spring is wound on the sleeve, and the other end of the clockwork spring extends to the outside through the opening; the first piezoelectric electrode layer and the second piezoelectric electrode layer are both fixed to the end, close to the opening, in the shell, and the first piezoelectric electrode layer and the second piezoelectric electrode layer are arranged above and below the clockwork spring respectively. The measuring tape type piezoelectric nano generator improves the material utilization rate of the PVDF film.

Description

technical field [0001] The invention relates to the field of piezoelectric energy conversion, in particular to a tape measure type piezoelectric nanogenerator. Background technique [0002] Currently, mechanical energy in the environment is mainly harvested in two ways: triboelectric nanogenerators (TENGs) and piezoelectric nanogenerators (PENGs), both of which can convert mechanical energy into electrical energy. TENG generates electrical energy by rubbing different materials to collect mechanical energy. It has the advantages of high output voltage, small volume and mass, and low cost. However, the current is relatively small and is greatly affected by the environment, which limits its application. PENG has the advantages of large energy output, long service life, convenient manufacture, simple design, and relatively stable output. Piezoelectric nanogenerators (PENGs) have received extensive attention due to their ability to harvest energy from environments such as air fl...
