The in-situ monitoring of structural integrity in large structures requires a substantial number of sensors. This presents problems especially due to the complexity of their electrical connections. This paper describes a monitoring system based on embedded ultrasonic sensors, which are interfaced using a license-exempt telemetry band to a remote data acquisition system, The sensors themselves are designed for the inspection of carbon fiber composite plates and involve the embedding of piezoeletric and piezocomposite components as well as acoustic fiber waveguides.
