Abstract

Disposable or single-use sensor labels sense a parameter and record the sensed parameter having: a semi-permeable medium or substrate with a parameter-sensitive and activatable developer. The developer, when activated, exhibits a detectable manifestation of a changed state that progresses over time. The detectable manifestation of this changed state is read and recorded to log parameter change data. Further, a method of using the sensor label monitors viability of a material associated with the label, such as for freshness and security assessment that is recorded for archival or reporting or quality control purposes. A changed state is exhibited that progresses over time, associating the label with a material to be monitored and positioning same into a given environment, and the recording can track the changed state against time.
