Description
technical field [0001] The invention relates to a power generation floor based on a dielectric elastic body, which belongs to the field of new energy. Background technique [0002] There is a large amount of energy dissipation in the environment, and the energy generated by pressure is a very typical environmental energy loss. At present, power generation floors based on electromagnetic principles and piezoelectric principles have come out, but these power generation floors are not sensitive to small external force excitations, or are not suitable for power generation occasions with low-frequency energy sources, and are prone to aging after long-term use. However, the present invention proposes a power generation floor based on a novel structure of a dielectric elastomer material. The present invention has a simple structure, is easy to install, and has a high energy conversion rate. Contents of the invention [0003] The object of the present invention is to provide a po...
