Description

Technical Field

[0001] The invention relates to the technical field of dielectric elastomer power generation, in particular to a piezoelectric biased wave energy dielectric elastomer generator. Background Art

[0002] Different from traditional power generation technology, dielectric elastomer power generation technology is a new, renewable, clean, electrostatic power generation technology. Flexible electrodes are processed on the upper and lower surfaces of dielectric materials to create elastic capacitors. When the two ends of the flexible electrodes are connected to a DC voltage source, the dielectric material will shrink along the direction of the power lines and expand in a plane perpendicular to the power lines. This phenomenon is called the electrostrictive effect. Dielectric elastomer power generation is the reverse use of the electrostrictive effect, using the elastic capacitor composed of dielectric materials as an electric energy generation unit, that is, a dielectric elastomer generator.

[0003] Dielectric elastomer power generation requires a bias voltage to construct an electric field for electromechanical conversion. However, stable and long-lasting high-voltage power supplies are difficult to obtain in actual engineering. To address this technical problem, a dielectric elastomer generator driven by wave energy and obtaining a bias voltage through piezoelectric power generation was invented.

[0004] When a piezoelectric material is deformed by an external force, it will generate equal and opposite charges of positive and negative on the opposite surfaces of the force, thereby generating voltage. When the external excitation is in the form of resonance, the piezoelectric output voltage is alternating current. After the alternating current generated by the piezoelectric is rectified by the bridge rectifier circuit, the electrical energy can be stored in the energy storage capacitor for future use.

[0005] With the development of society, energy crisis and environmental problems are becoming increasingly serious. The country has stepped up efforts to promote the application of renewable energy, aiming to build an environmentally friendly and resource-saving society. Dielectric elastomer power generation technology meets the expectations of social development. How to provide a device that uses piezoelectric voltage to bias the dielectric elastomer power generation is an urgent problem to be solved by technicians in this field. Summary of the invention
