Flexible electronics are gaining attention and momentum in the market. To achieve fully flexible electronic products, there is a growing demand of compatibly flexible components, including electrodes. Our technology of "Electrochemical Replication and Transfer" (ERT) has been developed to fabricate flexible and transparent electrodes by embedding high resolution conductive patterns in flexible substrates. These electrodes are highly flexible and can be freely bent or folded without performance degradation. They can be applied on flexible consumer gadgets, solar cells, smart windows, and different kinds of wearable smart electronics, such as high-tech fashion items and medical devices.
