Paper Abstract

In this paper, we develop a field-portable small-size impedance measurement system for structural health monitoring. The system consists of a rectangle wave generator, computer (or microcomputer), AD converter and piezo-electric element. We present some experimental results for testing the torque loose in the bolt for a truss structure. The results indicate that an accuracy of the impedance measurement system proposed in this paper is almost as accurate as the commercial multipurpose impedance analyzer, and it could be used on the structures for health monitoring.
