Abstract

Disclosed herein are gel-based temperature indicators that include a first absorbent substrate having opposing first and second faces and a first gel coupled to the first face. In some embodiments, the first gel is a gel at a first temperature, and the first gel turns to liquid at a second temperature. In some embodiments, the first absorbent substrate is configured to allow the first gel upon turning to liquid to diffuse through the first face toward the second face.
