Abstract
A vehicle interior panel includes a color-changing element with an active layer configured to change from a first color to a different second color when a voltage is applied across top and bottom electrode layers. The top electrode includes fullerenes in a configuration that is visibly transparent and permits the color-changing element to bend along sharp radii and/or stretch without losing electrical continuity. Fullerenes including ellipsoidal elements can provide these characteristics.
