Abstract

The performance of sensors is often limited by the structural characteristics of the single form of conductive filler, making it difficult for sensors to simultaneously consider the broad sensing range and high sensitivity. How to achieve high sensitivity and broad working range of sensors through innovative sensing materials and sensor structure design remains a challenge. Here, a flexible sensor with multidimensional sensing materials and a double-layer structure is constructed. It consists of a high-performance CNTs@Ag-MXene-TPU sensing layer and a TPU flexible layer with significant deformability. Thanks to the synergistic effect of the double-layer structure and multidimensional sensing materials, this sensor has a high sensitivity of up to maximum gauge factor of 12216.3 and a wide sensing range of 300 %. Its response time and recovery time can reach 200 and 250 ms, respectively, and it also exhibits excellent cycling stability.
