Installation and maintenance costs, and improved reliability of structural integrity monitoring in industrial applications demanding a large number of sensors applied to the structure can be achieved using wireless links between the sensors. This paper describes a wireless network system designed to interconnect a variety of ultrasonic transducers. Miniaturized wireless-coupled sensors which incorporate the sensor drive electronics, a DSP and Bluetooth communication module have been developed, initially for thickness measurement but capable of being reconfigured for time-of-flight crack monitoring, large area mapping using Lamb wave arrays and passive acoustic emission sensing. A networked system capable of inter-sensor and base station communications in an industrial environment is in progress and preliminary results obtained are presented.
