A customizable temperature exposure indicator and methods for making the same are disclosed. The temperature exposure indicator includes a substrate, a printing region of the substrate forming a heat sensitive media that is configured to darken when it is heated by a thermal printhead, the darkening being permanent with respect to subsequent cooling of the media; at least one memory thermochromic composition provided on an indicator region of the substrate, the thermochromic composition is configured to have high temperature color state when it is heated above a high temperature threshold, and to remain in the high temperature color state until it is cooled below a low temperature threshold, the thermochromic composition is configured to have a low temperature color state when it is cooled below the low temperature threshold and to maintain the low temperature threshold until it is heated above the high temperature threshold.

Semi-irreversible temperature exposure sensor customizable by thermal printer

A wristband has a flexible elongated body with an open state in which the wristband is capable of being positioned in a planar configuration and a closed state in which the wristband is wrapped in a loop. An RFID circuit is supported by the body and is positioned on the body such that the RFID circuit is configured to be included in the loop when the wristband is in the closed state. An elongated conductive element is supported by the body and is positioned on the body such that the elongated conductive element is configured to be included in the loop when the wristband is in the closed state. The elongated conductive element is spaced away from the RFID circuit and extends circumferentially about the loop in the closed state.
