Sensor networks embedded on structures, such as pipes, bridges, railways, aircraft wings and fuselage, among others, are required to transfer data related to the health of the structure. This data is typically sent to a central location where it can be processed, displayed, and analyzed. Typical Structural Health Monitoring (SHM) uses embedded ultrasonic transducers exclusively for non-destructive evaluation (NDE) purposes, whereas data transfer is performed over separate wireless radio frequency (RF) links. Ultrasonic systems, however, are also effective as a communication technology, and in fact may prove to have crucial advantages over RF-based sensor networks in certain scenarios.
