Abstract

In recent years, flexible sensors have attracted the interest of researchers due to their excellent potential for applications in health monitoring, flexible displays and motion detection. However, they still have much room for improvement in terms of luminescent color and flexibility. In this paper, a hydrogel-based electroluminescent wearable sensor device was developed. The hydrogel has good flexibility, antifreeze and transmittance (about 90%). And it can generate profound feedback signals in response to deformation caused by external force and human movement (such as finger bending). The electroluminescent device assembled with hydrogel as transparent electrode and ZnS:Cu + PDMS composite film can emit blue and green colors of light under voltage drive of different voltages and frequencies. In summary, the sensor device is simple to manufacture and proves its potential application in cold-resistant display screens, wearable devices, soft robots and electronic skin.
