Paper Abstract

This paper considers a wireless approach to health and usage monitoring of advanced composite materials. It uses a modular approach supporting, in particular, high performance system fabricated with composite panels fastened to an underlying frame. The panels are fabricated so as to include integrated circuit (IC) sensors placed in the various prepreg layers during layup. Various aspects in the development and performance of these IC sensors are described in the paper. Since the embedded sensors do not include an internal power source, interrogator circuitry has also been developed. This unit supplies power to sensor within the composite panel and obtains transducer data from the sensors, both via wireless techniques. This unit and its interface to the embedded sensors are discussed. Finally, a description is given of expected overall system monitoring using the sensor and interrogator devices being presented.
