Abstract
A flexible sensor label including a reservoir chamber configured to store an activation medium, a plurality of first chambers, and a plurality of second chambers. Each first chamber has an associated first temperature and stores an irreversible thermochromic polymer that is altered and irreversibly changes color in response to the activation medium being released and coming into contact with the irreversible thermochromic polymer in the first chamber and an environmental temperature of the flexible sensor label corresponding to the associated first temperature of the first chamber. Each second chamber has an associated second temperature and stores a reversible thermochromic polymer that is altered and reversibly changes color in response to the activation medium being released and coming into contact with the reversible thermochromic polymer in the second chamber and the environmental temperature of the flexible sensor label corresponding to the associated second temperature of the second chamber.
