Background
Piezoelectric nano-generator: the miniature generator converts the bending and compression mechanical energy into electric energy by utilizing the piezoelectric property and the semiconductor property of a special nano material (zinc oxide).
Piezoelectric material: crystalline material that when subjected to a compressive force develops a voltage across the two terminals. It is known that the application of a certain external force in a specific direction to some materials having dielectric properties causes polarization in the material and results in the accumulation of positive and negative charges, respectively, on opposite surfaces, showing a negative polarity. After the applied external force is removed, the original form is restored, and the electrical property disappears, which is called piezoelectric effect. And a material having such characteristics is called a piezoelectric material. By utilizing the piezoelectric property of the piezoelectric material, kinetic energy, potential energy and the like can be ingeniously converted into electric energy.
Most of the existing piezoelectric power generation devices applied to the sea are moored underwater, and when water flows through the piezoelectric power generation devices, the piezoelectric power generation devices drive the devices to generate power.
