Flexible membrane keyboard and electronic products based on triboelectric generator

Abstract

The invention discloses a flexible membrane keyboard and electronic products based on a friction generator. The flexible membrane keyboard includes: a key layer, a common layer, and a signal processing circuit; the key layer includes a plurality of independent key areas, each key area corresponds to a key; each key area includes a key electrode, and each key electrode are respectively connected to the signal processing circuit through mutually independent key wires; the common layer includes a common electrode, and the common electrode is connected to the signal processing circuit through a common wire; wherein, a friction interface is formed between the key layer and the common layer or, the common layer includes a structure that forms a friction interface; or, the key layer includes a structure that forms a friction interface. The flexible membrane keyboard provided by the present invention has better flexibility, is lighter and thinner, and can be conveniently integrated and applied to various electronic products.

Description

technical field [0001] The invention relates to the field of peripheral equipment of electronic products, and more specifically relates to a flexible membrane keyboard based on a friction generator and electronic products. Background technique [0002] The keyboard is the main input device of electronic products such as computers. At present, keyboards are mostly rigid bodies made of plastic, which are not only bulky and inconvenient to carry, but also rigid keys are likely to cause finger joint lesions for people who use computers for long-term work. Moreover, the volume occupied by the rigid keyboard is large, and it is difficult to be applied to small electronic products, such as mobile phones, handheld computers and other electronic products. [0003] The flexible membrane keyboard is a kind of keyboard with flexible characteristics, which can be folded or rolled up, is easy to carry, and can be conveniently applied to small electronic products. At the same time, its i...

AI Technical Summary

Problems solved by technology

The current flexible membrane keyboard is mostly composed of four parts: the panel, the upper circuit, the isolation layer, and the lower circuit. Due to the limitation of the structure, the thickness is too thick and the flexibility is not enough.
