Embodiment Construction

[0033] The invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] As we all know, conductive copper foil tape is a common commercial material, which consists of three parts, including copper foil, backing paper and silicone oil. The backing paper and silicone oil form a triboelectric pair, and the copper foil serves as a conductive electrode. At the same time, due to its good sustainability and flexibility, the backing paper plays a supporting role.

[0035] refer to figure 1 , is the humidity sensor based on the triboelectric nanogenerator described in the present invention, comprises two arched structures up and down; The concave surfaces of the two arched structures are arranged oppositely, and the two ends are bonded to each other; The upper arched structure includes Arranged conductive copper foil, backing paper and silicone oil layer, the lower arched structure includes conductive copper foil, silicone oil laye...

Abstract

The invention discloses a humidity sensor based on a friction nano-generator and a method thereof. The humidity sensor comprises an upper arch structure and a lower arch structure. The upper arch structure comprises a conductive copper foil, bottom paper and a silicone oil layer which are arranged from top to bottom; and the lower arch structure comprises a conductive copper foil, a silicone oil layer and bottom paper which are arranged from bottom to top. The silicone oil and the silicone oil paper form a triboelectric pair, the silicone oil paper plays a role of a supporting structure, and the conductive copper foil adhesive is used as a conductive electrode. The paper has certain hydrophilicity and serves as a constituent part of the friction nano-generator, an output signal of the paper is not enough to obviously reflect humidity change. The hydrophilicity of the paper is increased by adding lithium chloride to the paper, so that the output signal of the friction nano-generator better reflects the humidity change. The humidity sensor based on the friction nanometer generator has the advantages of being light in weight, small in size, good in stability, easy to manufacture, andlow in cost, and a potential solution is provided for achieving a self-powered humidity sensing system.

Description

technical field [0001] The invention relates to a humidity sensor based on a triboelectric nanogenerator. The humidity sensor can be used to measure the humidity of the environment, and can be widely used in agriculture, electronic industry, storage and medical treatment. The research and development provides a potential solution for realizing a self-powered humidity sensing system. It belongs to the field of nano energy. Background technique [0002] In recent years, with the development of industrial Internet of Things, environmental monitoring and smart communities, humidity sensors have played an increasingly important role in wireless sensor networks, electrical equipment, food safety, environmental protection and many other fields. The continuous operation of sensors still depends on traditional electricity, but following it, some key environmental issues are becoming more and more prominent, especially the deterioration of urban environment, which is closely related...
