Description

technical field [0001] The invention relates to the technical field of dielectric elastomers, in particular to a stacked dielectric elastomer wave energy collector. Background technique [0002] A dielectric elastomer is a material that can deform under an applied electric field and mechanical force, and can convert mechanical energy into electrical energy by elastic recovery after the mechanical force is removed. Utilizing this feature, wave energy harvesters can be made to convert mechanical energy into electrical energy. [0003] In order to make the dielectric elastomer produce a larger electrostrictive effect, a very high driving electric field is often required. In order to obtain a higher electric field, the film of the dielectric elastomer is often made very thin. Such a thin film only needs Very small pressure will produce wrinkles and fail. At the same time, as the mechanical force exceeds the tensile limit, the material will crack and fail, reducing the service l...

[0003] In order to make the dielectric elastomer produce a larger electrostrictive effect, a very high driving electric field is often required. In order to obtain a higher electric field, the film of the dielectric elastomer is often made very thin. Such a thin film only needs Very small pressure will produce wrinkles and fail. At the same time, as the mechanical force exceeds the tensile limit, the material will crack and fail, reducing the service life; at the same time, the internal molecular interaction of existing elastomers will generate internal heat when they are repeatedly deformed. , the thermal energy is too late to diffuse and will also reduce the service life of the elastomer
