Flexible time-temperature sensing label system

A method comprising:

• capturing, with a mobile computing device, an image of a flexible sensor label having a unique identifier included on the flexible sensor label, the flexible sensor label including (i) a reservoir chamber configured to store an activation medium, (ii) a plurality of first chambers, each first chamber of the plurality of first chambers having an associated first temperature and storing an irreversible thermochromic polymer, wherein the irreversible thermochromic polymer 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, and (iii) a plurality of second chambers, each second chamber of the plurality of second chambers having an associated second temperature and storing a reversible thermochromic polymer, wherein the reversible thermochromic polymer 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;
• and
• transmitting, with the mobile computing device, the image of the flexible sensor label to a cloud network that includes a database, wherein the database is configured to store the image of the flexible sensor label.
