Abstract
A stable silk-screen printing flexible sensor comprises cloth, an inner bonding layer, a sensor, an outer bonding layer and an electrically conductive unit; the outer surface of the cloth is sequentially connected with the inner surface of the inner bonding layer, the inner surface of the sensor and the inner surface of the outer bonding layer, the outer surface of the outer bonding layer makes contact with the atmosphere, the sensor is connected with the electrically conductive unit, and the sensor is a strain sensor. The application mode is silk-screen printing. In the manufacturing process,a rubber sheet is flatly placed on the horizontal plane, then a release agent, the outer bonding layer, the sensor, the inner bonding layer and the cloth are sequentially arranged on the rubber sheet, then the cloth is pressed downwards and flattened to obtain a blank, and then the overturned blank is dried. The stable silk-screen printing flexible sensor is easy to apply to wearable equipment, good in consistency, high in firmness, rich in appearance style, high in manufacturing efficiency and wide in application range.
Description
technical field [0001] The invention relates to a flexible sensor applied to textiles, in particular to a stable screen-printed flexible sensor and a manufacturing process thereof, which are specifically suitable for improving consistency and firmness on the basis of satisfying the application of wearable devices. Background technique [0002] In recent years, wearable electronic devices have developed rapidly and become an important trend in the development of next-generation electronic products. As an important branch of wearable electronic devices, wearable strain sensors should have certain mechanical flexibility, fit, high stretchability, high sensitivity, fast response, high durability, etc., in order to realize their wearable characteristics. And its wide application in personal medical treatment, motion detection, human-computer interaction, virtual reality entertainment technology, etc. However, traditional strain sensors based on semiconductors or metal foils are ...
