Description

technical field [0001] The invention belongs to the technical field of piezoelectric power generation, and in particular relates to a piezoelectric power generation device and a power generation method for generating power through human body kinetic energy excitation. Background technique [0002] At present, with the increasing demand for energy, the development and utilization of various new energy sources have been proposed one after another, and the recovery of human kinetic energy has gradually become a hot spot in scientific research. The kinetic energy of the human body is converted into electric energy for power generation, which can reduce costs and improve economic benefits. The traditional mechanical electromagnetic human body power generation structure is generally to install a generator on the sole of the shoe or other parts of the human body, so that the kinetic energy of the human body is converted into electrical energy to generate electricity. The Chinese u...
