Stretchable and transparent electrodes with the combination of high transmittance, electrical conductivity and stretchability are essential for electronic device. Currently, indium tin oxide (ITO) coated film is most often used because ITO has high transparency to visible light and low sheet resistance for electrical current conduction. However, ITO is costly due to limited resources and it is easily brittle. Recently, advances in nano materials research have opened the door for other transparent conductive materials like CNT, graphene, and nanowire. Here we report alternative metallic nanogrid for highly stretchable and transparent electrodes with high performance due to its high aspect ratio. As a metallic grid has almost 20nm feature size with 400nm height and also it is embedded in PDMS, it is expected to have highly stretchable and high performance compared to current reported transparent electrode. |
