Patent ID: 7755489

Claim:
An intelligent package monitoring system, comprising: an electronic module for tamper monitoring and identification of a package, said electronic module including a distributed electrical circuit printed on a dielectric film capable of being wrapped about said package 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; a plurality of passive acoustic wave sensors for package identification and monitoring at least one physical parameter of said package content, said plurality of passive acoustic wave sensors capable of electronically communicating with an antenna for wirelessly transmitting a signal; and at least one acoustic wave interdigital transducer associated with said plurality of passive acoustic wave sensors and said electronic module, wherein said at least one acoustic wave interdigital transducer is capable of power harvesting in order to generate an RF power for biasing said electronic module, and thereby permitting a passive wireless monitoring of a structural integrity of said dielectric film and said package in said logistic chain thereto.
