Abstract
An intelligent packaging system utilizing acoustic wave devices includes an electronic module, a SAW ID, various passive SAW sensors and a printed antenna. The passive SAW sensors include a SAW pressure sensor, a SAW temperature sensor and one or more SAW chemical sensors for monitoring physical parameters of a package content. The electronic module generally includes a printed large area distributed electrical circuit, an impedance transformer and a SAW transponder for realizing passive wireless monitoring of the structural integrity of the package. A separate power harvesting antenna and/or a separate dual band antenna can generate radio frequency (RF) power for biasing components associated with the electronic module.
