Stretchable electroluminescent devices have been obtained via special device architecture or intrinsically stretchable materials. The challenges in fabricating intrinsically stretchable EL devices with high and robust performance are in many facets, including stretchable conductors, emissive materials, and compatible processes. For the stretchable transparent electrode, ionically conductive gel, conductive polymer coating, and conductor network in surface of elastomer have all been proven useful. The stretchable EL materials are currently limited to conjugated polymers and phosphor particles embedded in elastomer matrices. The presentation will provide an overview of the important materials and approaches and describe stretchable polymer light emitting electrochemical cells.
