Abstract

The invention provides a flexible sensor and a preparation method thereof. Through using rubber with high flexibility as a substrate layer, restriction of a substrate preparation material in an existing flexible sensor is prevented, and bending degree and stretching degree of the flexible sensor are improved. The sensor comprises the components of the substrate layer which is formed by the rubberwith high flexibility, a conductive layer on the substrate layer, conductive contacts and a passivation layer on the conductive layer, and a lead which is connected with the conductive layer through the conductive contacts and is used for transmitting a sensing signal.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a flexible sensor and a preparation method thereof. Background technique [0002] In recent years, the flexibility of electronic products has become a mainstream trend, and how to develop sensors with good flexibility and ductility has become an important research topic. [0003] At present, flexible sensors manufactured in the industry usually use polyurethane sponge or cellulose paper to make the base layer, and then use conductive materials such as metal oxides or metal nanowires to make the conductive layer. However, the base layer made of polyurethane sponge or cellulose paper has pull The problem of poor stretching effect limits the application range of the base layer. [0004] To sum up, at present, the base layer of flexible sensors in the industry has the problem of poor stretching effect. Contents of the invention [0005] The embodiment of the present invention pro...
