Large area distributed sensor
First Claim
1. A wireless monitoring system, comprising:
- a distributed electrical circuit printed on a dielectric film for wrapping pallets or containers in a logistic chain, wherein said distributed electrical circuit detects a rupture of said dielectric film through an electrical resistance change of at least one element of said distributed electrical circuit, wherein said electrical resistance change is indicative of a potential tampering event;
an electronic module that conditions and processes a signal transmitted from said distributed electrical circuit and thereafter transmits said signal wirelessly via an antenna to a monitoring station; and
a monitoring station that communicates with a network and said electronic module, which permits a user in real time to receive data concerning said potential tampering event associated said pallets or containers based on said electrical resistance change of said at least one element of said distributed electrically circuit, thereby permitting wireless monitoring of the integrity of said dielectric film and said pallets or containers in said logistic chain.

Abstract
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.
