Embodiment Construction

[0040] The present invention will be further described below in conjunction with drawings and embodiments.

[0041] Embodiments of the present invention are as follows:

[0042] Such as figure 1 Shown is the fabrication flow for the complete device.

[0043] (1) A patterned graphene electrode is generated by laser induction on the surface of polyimide (PI) film. The graphene electrode includes a power generation part and an interdigital part; the power generation part is a square complete metal sheet structure, and the interdigital part is Typical interdigitated electrode structure, the wires at both ends of the interdigitated part are drawn out as the output terminals of the power supply.

[0044] Laser induction is specifically to cut the polyimide film into the required size and fix it in the prefabricated mold, using a laser with a vertical distance of 7.5cm, a scanning speed of 10mm / s, and an output power of 1-5W on the surface of the polyimide film. After processing, ...

Abstract

The invention discloses an integrated flexible self-charging power source for agricultural environment energy collection and a preparation method. The power source comprises polydimethylsiloxane and agraphene electrode which is completely packaged in the polydimethylsiloxane; the graphene electrode comprises a power generation part and an interdigital part; the power generation part and the interdigital part are integrally packaged in the polydimethylsiloxane; the interdigital part is covered with solid electrolyte; and two ends of the interdigital part of the graphene electrode are led out through wires to serve as two output ends of the power source. The power source has the advantages of integration, high flexibility, dual-mode energy collection form and simplicity in preparation, canmaintain long-time stable work and is a good substitute of a traditional agricultural energy supply system.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to an integrated flexible self-charging power supply for agricultural environment energy collection and a preparation method. Background technique [0002] Modern agriculture, which is becoming increasingly intelligent and modular, has an increasing demand for various sensors. However, these devices also have higher requirements for power supply modules, including long-term sustainable energy supply, stable output, and outstanding environmental adaptability. At present, triboelectric nanogenerators invented based on triboelectrification and electrostatic inductive coupling effects are considered to be a potential substitute for traditional rigid power sources. Through the selection of advanced materials and the design of structures, various types of triboelectric generators have been developed and applied in various fields, such as human behavior sensing, ocean energy harvest...
