Abstract
Inspired by animals in nature, such as chameleons, frogs, and cephalopods, the remarkable capability of changing one's skin color has drawn considerable interests due to its wide applications in camouflage, warning methods, and visual communications. Today, research on electronic skins (e-skins), imitating biological skin by quantifying external stimuli, to mimic this unique color-changing function has been achieved based on the integration of a matrix of displays and sensors; however, integrated systems possess bulky and complicated fabrication processes. Here, the first attempt to demonstrate a single user-interactive e-skin device with color-changing response upon applied external strain is made, while using a cost-effective and space-saving method, which promises to open new possibilities for the development of next-generation e-skins with visual response.
