FLEXIBLE STRETCHABLE STRAIN SENSOR AND PREPARATION METHOD THEREFOR

摘要

A flexible stretchable strain sensor, comprising a flexible substrate (1), wherein a flexible microchannel (10) is arranged in the flexible substrate (1), a liquid conductor or a semi-liquid conductor (3) is arranged in the microchannel (10), and electrodes (2) are arranged at both ends of the microchannel. A wearable device having the flexible stretchable strain sensor. A preparation method for the flexible stretchable strain sensor, comprising the following steps: preparing the flexible substrate (1) having the microchannel (10); and injecting the liquid conductor or the semi-liquid conductor (3) into the microchannel (10), and inserting the electrodes (2) at both ends of the microchannel. The flexible stretchable strain sensor provided by the present invention has the geometrical characteristics of high flexibility, stretchability and being thin, may be directly integrated with any flexible actuator, has high sensitivity and strong anti-interference capability, and may still work normally when the strain reaches 300%.
