ABSTRACT:
Cumulative thermal exposures monitors and remote indicating cumulative thermal exposure monitors and system for reading the same are disclosed. The monitors have a thermally insulative housing with a cavity and a thermally-responsive member therein formed of shape memory material, which may be provided with a coating or sheath of insulative or shape memory polymer material, that gradually changes from a first shape to a second shape over a prescribed temperature range wherein the thermal capacity and insulative properties of the housing, cavity, and shape memory material transition temperature range are correlated relative to one another and calibrated to closely match a thermal decay profile (time-temperature profile) of the product being monitored. In remote indicating embodiments, the data can be retrieved remotely via RF transponder technology without directly viewing the monitor device.
