This paper is concerned with the development of Piezoceramic Embedded Impedance Measuring System for large truss type structures, such as the bridges or steel reinforced structures. The system consists of a sine wave generator, AD converter and computer (or microcomputer). The wave generator supplies the alternating voltage to the piezocells for generating an elastic stationary wave on the structure. The stationary wave change, due to the torque applied to the bolt which is used to joint the beams of a truss structures, is then measured by the same piezocells' electric impedance change. The proposed PEIMS is verified by comparing with the commercially available impedance analyzer. The experiment results show that the impedance change due to the damage can be evaluated at the same high accuracy as the commercial impedance analyzer does, by a new proposed template shift distance ΔS.
