Sensor for monitoring an article

摘要

A sensor has a substrate with a first surface having a substantial area, a conductive trace defining a conductive path on the substrate between first and second locations, and an adhesive on the first surface for adhering the sensor to an object to be monitored in an operative state. A weakening is provided in the substrate to cause separation/tearing of the substrate in a predetermined fashion as an incident of a force being applied to the substrate with the sensor in the operative state tending to peel the sensor off of the object to be monitored. The conductive trace is arranged on the substrate so that as the substrate separates/tears in the predetermined fashion, the conductive path defined by the conductor trace is interrupted.
