Stretchable and transparent electroluminescent device driven by triboelectric nanogenerator

Flexible and stretchable electronic devices have attracted considerable interests for their significant impact on future human life. Here, we reported an intrinsically stretchable and transparent alternating current electroluminescent device driven with a triboelectric nanogenerator. The electroluminescent layer of ZnS:Cu-embedded-polydimethylsiloxane was sandwiched with two electrodes consisted of single-walled carbon nanotubes. The alternating current electroluminescent device is stretchable, flexible and transparent, and exhibits bright and durable electroluminescence under quasi-static and dynamic deformation at the tensile strain up to 100%. The integrated system displays a stable output intensity under periodically mechanical stimuli, and retains 98.4% of its original luminance after continuous operation for 1000 cycles. This hybrid system might find its future applications in soft robotics, human-machine interfacing, and self-powered monitoring.
