Cincinnati OH US - The present invention provides a reversible piezochromic system that changes appearance upon application of a mechanical force. The reversible piezochromic system includes a cavity defined by a first substrate and a second substrate. The cavity includes at least a first fluid. The first fluid spreads when a mechanical force is applied to the system. The relaxation time of the first fluid depends upon the internal forces of the system. These internal forces at least include the surface energy differences between the substrates and the fluid or fluids, and the rheological properties of the fluid or fluids. | 01-17-2013 |
