LARGE AREA DISTRIBUTED SENSOR

摘要

A wireless monitoring system and method. A distributed electrical circuit can be printed on a dielectric film for wrapping pallets or containers in a logistic chain, wherein the distributed electrical circuit (e.g., a Wheatstone Bridge) detects a rupture of the film through an electrical resistance change of one or more elements of the distributed electrical circuit. The electrical resistance change is indicative of a potential tampering event. An electronic module can be provided that conditions and processes a signal transmitted from the distributed electrical circuit and thereafter transmits the signal wirelessly via an antenna to a monitoring station. Additionally, a monitoring station can be implemented, which communicates with a network and the electronic module, and permits a user in real time to receive data concerning the potential tampering event.
