Selective Intense Light-Induced High-Performance Washable Transparent Electrodes

Recently, various electronic devices, such as foldable displays, disposable sensors, and flexible batteries have been widely demanded. Accordingly, we tried to create extremely flexible conductive features that can tolerate severe mechanical stress using photonic sintering process. Additionally, based on significant differences in adhesion between light-exposed and non-exposed regions with respect to the underlying substrate, it was confmned that patterning of conductive electrodes could be easily accomplished on large area. The potential of IPL treated electronic conductive features were clearly demonstrated by fabricating various emerging devices such as a light-emitting diode circuit and a flexible transparent heater with unimpaired functionality under various deformations. Our results facilitate their widespread application in future electronics, such as wearable e-skins, smart textiles and foldable display.
