Abstract

A flexible sensor based on liquid metal comprises an upper covering layer, a lower covering layer, and a placing chamber between the upper covering layer and the lower covering layer. The length of the placing chamber is lower than the length of the upper covering layer and the length of the lower covering layer. A flexible inner conductor is arranged in the placing chamber. Two ends of the innerconductor are respectively connected with the inner ends of a first wire and a second wire. The outer ends of the first wire and the second wire arranged outside an outer wrapping layer. The outer wrapping layer is made of an insulating material. The inner conductor is mixture of glue and conductive powder. In manufacture, the inner conductor enters a position between the upper covering layer andthe lower covering layer through an injection or screen printing manner. The flexible sensor has advantages of relatively high sensitivity, easy application to a wearable device, relatively high consistency and relatively high accuracy.

Description

technical field [0001] The invention relates to a sensor applied to textiles, in particular to a liquid metal-based flexible sensor and a manufacturing process thereof, which is particularly suitable for enhancing consistency 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 usually rigid and have low...
