Abstract:
1. A reversible piezochromic system comprising: a first substrate; a second substrate; a cavity defined by an inside surface of said first substrate and an inside surface of said second substrate; and at least a first fluid disposed within said cavity, wherein said first fluid is colored wherein upon application of a force to the system the first fluid spreads from an equilibrium state to an active state, and upon relief of said force from said system the first fluid returns to said equilibrium state; wherein the inner surface of at least one of said first substrate or second substrate comprises a patterned inner surface having at least a higher surface energy area and at least a lower surface energy area; wherein said patterned inner surface of at least one of said first substrate or said second substrate is in contact with the first fluid, the first fluid having a viscosity ranging between 100,000 cPs to 5,000,000 cPs at a temperature between 5° C. and 40° C.
