Abstract

Transducer health monitoring is an important part of structural health monitoring. Recent results have shown that during active health monitoring, a faulty transducer can falsely indicate the existence of damage in a structure when in reality the fault exists in the transducer. This is because the received signals change due to iwo factors: (a) changes in the bond between the transducer and structure and (b) physical damage to the transducer. In this paper, an approach to transducer health monitoring is discussed which monitors changes due to transducer degradation. In addition, a structural health monitoring device that harvests energy from external sources has been developed. This device excites the structure with a high frequency (-1MhZ) tone burst. Results of transducer and structural health monitoring using energy-harvested power are discussed in this paper.
