SENSORS AND METHODS FOR DETERMINING WHETHER AN ITEM HAS BEEN EXPOSED TO AN ENVIRONMENTAL CONDITION

摘要：

A method for determining whether an item has been exposed to an environmental condition during a monitoring period. The method includes placing a sensor at least in proximity to the item at the beginning of the monitoring period so that the sensor will be exposed to a level of an environmental condition that can be correlated to an exposure level of the item to the environmental condition; reading the sensor; and determining from reading the sensor whether the item has been exposed to the environmental condition. The sensor includes a detecting material comprising a photochromic or photothermochromic material, the detecting material selected so that upon exposure to the environmental condition the detecting material exhibits a detectable color change.

一种用于在监视期间确定物品是否已经暴露于环境条件的方法。该方法包括在监测周期开始时将传感器至少放置在物品附近，使得传感器将暴露于可以将物品的曝光水平与环境条件相关联的环境条件的水平; 读传感器; 并且从读取传感器确定物品是否已经暴露于环境条件。传感器包括检测材料，其包括光致变色或光致变色材料，所述检测材料被选择为使得当暴露于环境条件时，检测材料表现出可检测的颜色变化。
