Abstract
With the rising interest from many areas, such as human motion detection, human health monitoring, wearable devices, robotics, and structural health monitoring, strain sensors with the features of high flexibility, stretchability, sensitivity, stability, and low cost attract considerable attention. This paper aims to introduce a low cost, highly stretchable microfluidic-based strain sensor capable of detecting strain change up to 160%. The sensor is comprised of a electrolyte-enabled long winding microchannel integrated with a pair of interconnects and a silicone-based packaging. While the sensor is stretched along the sensor length, the transducer pair's overall resistance increases due to the elongation of the microchannel length and reduce of the microchannel cross-section.
