Embodiment Construction

[0026] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0027] Triboelectric nanogenerators (TENGs) are easier to harvest random energy than other technologies for generating electricity. Triboelectric nanogenerator is a combination of triboelectric and electrostatic induction technology, it has the characteristics of high efficiency, low weight, low loss, the important thing is that this technology can collect the energy produced by nature, including the energy produced by human movement. Two kinds of dielectric materials are usually used. After physical contact, electrons are transferred on the respective surfaces, and the induced charges generated by the local charge imbalance pass through the conductor behind the dielectric layer to be balanced in the external current circuit, and this process converts mechanical energy into electricity.

[0028] Aiming at the current development trend of...

Abstract

The invention relates to a flexible stretchable power generator based on electrification by friction; the flexible stretchable power generator comprises a friction layer, the first electrode filling layer, the second electrode filling layer, the first assembling layer and the second assembling layer; a groove channel is arranged inside the first assembling layer and the second assembling layer; the first electrode filling layer fills in the groove channel corresponding to the first assembling layer, thus forming the first contact friction surface; the second electrode filling layer fills the groove channel corresponding to the second assembling layer, thus forming the second contact friction surface; the friction layer is arranged between the first and second contact friction surfaces. Theflexible stretchable power generator based on electrification by friction can gather motion signals in movements so as to form current, thus charging a wearable equipment battery and monitoring mechanical motions; the flexible stretchable power generator based on electrification by friction has very good transmittance, waterproofness and biology compatibility, and can provide important meanings for the electronic skin development and wearable equipment industry.

Description

technical field [0001] The invention relates to a flexible and stretchable power generation device based on triboelectricity. Background technique [0002] A wearable device is a portable device that is worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not only a hardware device, but also achieve powerful functions through software support, data interaction, and cloud interaction. Wearable devices will bring great changes to our lives and perceptions. Wearable devices mostly have the functions of interacting with human body behavior, monitoring, assisting, enhancing and expanding human body functions. Such devices need to have certain computing transmission capabilities and interactive detection capabilities, such as the ability to detect physiological changes in the human body and analyze and transmit them to operable terminals. It is very difficult to make such complex components into products that meet the requirements...
