ABSTRACT:
A thermal history indicator comprising a temperature sensitive material, a sensing device, a heat insulating material functioning to buffer the temperature sensitive material against temperature change, and an activation means. The triggering of the activation means allows a molten phase of the temperature sensitive material to interact with the sensing device, or cease interacting with the sensing device, thereby altering its chemical, biochemical or microbiological.
