With the rapid development of flexible sensory devices, flexible sensors have continued to grow in demand for applications in human motion detection, and so on. However, the presence of sensing signal hysteresis during loading/unloading processes of the strain sensor have always limited the various applications in the wearable sensory system in the term of sensing performance reliability. In this study, we demonstrated highly stretchable strain senor with a low hysteresis composed of CNT-elastomer nanocomposites. To find the simple strategy for achieve our goal, we designed the sensing performances of single structures of the devices. As a result, with increasing the CNT-elastromer nanocomposites layer, the electrical conductivity and resistance are improved and reduced, respectively. Moreover, the strain sensor shows the low hysteresis and high reliability of the detection performances. The results will be contributed to realize the wearable strain sensory systems in the future. |
