N2 - Lead zirconate titanate (PZT) based impedance transducers have been widely used in structural health monitoring (SHM). They have shown excellent capabilities in evaluation of structural health in terms of damage, deformation and load monitoring. However, in applications of large scale structures or in the case that structure to be monitored is difficult to access, the accuracy of data acquired is compromised due to long cables used to connect sensors and data acquisition equipment. Wireless technology is therefore desired in controlling health monitoring of aerospace, civil and mechanical structures to solve the problem. This paper presents a newly developed wireless impedance analyzer which is applied to monitor structural damage. The reliability of the wireless data acquisition system is analyzed by comparing signatures acquired using wireless impedance analyzer against those obtained from traditional cable connection.
