Abstract: Aspects of the present disclosure relate to phase-change materials. In accordance with an example embodiment, a phase-change material has a crystalline structure that manifests changes that increase as a function of time. For example, such changes may be implemented for monitoring the time that a perishable item has been exposed to an environment having a temperature that is greater than a threshold temperature. Based on the changes, a characterization is provided, indicative of the exposure of the phase-change material to the environment having the temperature that is greater than the threshold temperature.
