Problems solved by technology

The existing cam mechanism makes the deformation of the dielectric elastic body small, and cannot fully utilize the advantages of the large deformation of the dielectric elastic body, reducing the energy conversion efficiency; the number of dielectric elastic bodies in the existing crank-link mechanism is small, and the space utilization is limited. The rate is not high, which reduces the power generation efficiency
