All-printing fabrication for stretchable devices based on r2r processes

This study realizes a continuous printing fabrication process for large-area and mass production of stretchable devices on Roll to Roll (R2R) process. This continuous printing fabrication process is composed of R2R and dispensing printing processes to achieve the stretchable devices that contain hard and soft layers based substrate, and liquid metal wirings between circuit elements which are mounted on stretchable substrate. Hence, the mass production of stretchable devices can be fabricated stably and consistently by using this all-printing fabrication process. This work will contribute to the social implementation of stretchable devices.
