Stretchable variable color sheet that changes color with expansion and contraction

A Toyohashi University of Technology research team has succeeded in developing a variable color sheet with a film thickness of 400 nanometers that changes color when stretched and shrunk. The developed stretchable color sheets are expected to be applied to adhesive-type display elements, as they can adhere to skin or be transferred to various electronic devices at room temperature utilizing the high adhesiveness of elastomers.
