Extremely Stretchable Electrode based on Combination of InkJet-Printed Silver and Conductive Composite for Stretchable Lighting Applications

摘要

We have studied stretchable electrode based on combination of inkjet-printed silver electrode and conductive composite materials for stretchable lighting device application. We combined conductive composite materials with inkjet-printed metal thin film for high conductivity for both low and high elongation conditions. Our approach has advantages of simple patterning capability, high intial conductivity, and compensated low resistance sustaining under tremendously high tensile strain conditions when compared with previously reported methods. Our stretchable electrodes showed high condudctivity from the inkjet-printed silver electrode and maintained similar level of conductivity when they are elongated over 100%.
