Abstract: Methods and systems for monitoring an environment history of a component using an indicator array that includes energy exposure indicator pads direct-printed onto a surface of the component in a geometric pattern. Each of the plurality of energy exposure indicator pads in the geometric pattern may include a mechanochromic material, a first thermochromic indicator responsive within a first temperature range, a second thermochromic indicator responsive within a second temperature range, and a third thermochromic indicator responsive within a third temperature range, provided that the first, second, and third temperature ranges are distinct from one another.
