Embodiment Construction

[0025] The solution disclosed in the embodiment of the present invention uses a piezoelectric element with a conductive surface to output electric energy according to an alternating electric field in the environment. When the conductive surface of the piezoelectric element is charged, under the action of the alternating electric field in the environment, the charge on the surface of the piezoelectric element moves, causing the piezoelectric element to vibrate and deform, and then the piezoelectric element Electric energy is generated due to the piezoelectric effect, thereby converting the alternating electric field in the environment into electrical energy.

[0026] In the following, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0027] see now Figures 1A-1B , which shows a schematic diagram of a power supply device according to an embodiment of the present invention. like Figures 1A-1B As shown, the p...

Abstract

The present invention relates to a power supply device and an electronic system, wherein the power supply device comprises: a piezoelectric element with a conductive surface, used for alternating electric field in the environment when the surface is electrostatically charged Under the action, the electrostatic charge on the surface of the piezoelectric element moves, thereby deforming the piezoelectric element to generate electric energy. Using the power supply device and electronic system, the alternating electric field in the environment can be converted into electric energy.

Description

technical field [0001] The invention relates to a power supply device and an electronic system. Background technique [0002] There are electronic devices that operate 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, the power that can be supplied is limited, which cannot meet the power supply requirements of these electronic devices. [0003] Around environments such as substations and high voltage power transmission towers, alternating electric fields exist. If the alternating electric field can be converted into electrical energy and supplied to electronic devices operating in these environments, the difficulty of supplying power to electronic devices operating in such environments can be overcome. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide...
