Description
technical field [0001] The present application relates to the field of energy technology, and in particular, to a device and method for collecting vibration energy of an underwater hydraulic system based on a dielectric elastomer. Background technique [0002] With the development of society and technology, energy has become more and more important. With the gradual consumption of traditional energy and the advancement of environmental awareness, new energy and energy utilization technologies have received extensive attention. As a new type of smart material, dielectric elastomer has developed rapidly since the 1990s. It has the advantages of high energy density, large deformation range, low price and high electromechanical conversion efficiency, attracting a large number of scientists and researchers. focus on. Under a given bias condition, the dielectric elastomer induces the deformation of the film by external excitation and leads to a change in capacitance, thereby rea...
