Stretchable Light-Emitting Devices

Recent technological advances in materials have driven the development of stretchable light emitting devices that are normally fabricated on flexible or stretchable substrates. Stretchable display enables direction visualizing information from end users and providing the feed back the the devices and sensors mounted on the human skin. Generally, two different approaches can be made to achieve stretchability of the light-emitting device. One is using geometrically stretchable structures such as serpentine, buckling, nano-meshes. By downscaling the dimension of the materials, mechanical property of the materials can be significantly enhanced. The other approach is incorporation of intrinsically stretchable materials such polymers, nanomaterials or their composites. Currently we are working on both stretchable electrodes and devices using above two approaches
