Embodiment Construction

[0021] According to the solution of the embodiment of the present invention, the piezoelectric element is formed by using piezoelectric material and magnetic material. When the piezoelectric element is placed in an environment with an alternating magnetic field, the alternating magnetic field in the environment and the piezoelectric Under the interaction of the magnetic material in the element, the piezoelectric element vibrates, which causes the piezoelectric material in the piezoelectric element to deform, and the piezoelectric material in the piezoelectric element generates electrical energy due to the piezoelectric effect, thereby being able to utilize the environment An alternating magnetic field generates electricity.

[0022] In the following, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0023] see now Figures 1A-1B , which shows a schematic diagram of a piezoelectric element according to an emb...

Abstract

The invention relates to a piezoelectric element, a power supply device and an electronic system. The power supply device comprises piezoelectric material and magnetic material covered on the surface of the piezoelectric material. When placed in an environment with an alternating magnetic field, the piezoelectric element moves under the action of magnetic force borne by the magnetic material so as to enable the piezoelectric material to produce electric energy. By the adoption of the piezoelectric element, the power supply device and the electronic system, an alternating magnetic field in an environment can be converted into electric energy.

Description

technical field [0001] The invention relates to a piezoelectric element, a power supply device and an electronic system. Background technique [0002] In some environments, such as around substations and high voltage power transmission towers, alternating magnetic fields exist. But there is no technology that can conveniently utilize these alternating magnetic field energies at present. At the same time, some electronic equipment operates in environments such as substations and high-voltage power transmission towers. Due to the high voltage difference, it is impossible to directly supply power to these electronic devices, or even if it can supply power to these electronic devices, the power that can be provided is limited and cannot meet the power supply requirements of these electronic devices. Contents of the invention [0003] The purpose of the invention is to generate electric energy by using the alternating magnetic field in the environment, thereby improving the u...
