Abstract

In this paper, the global and local health monitoring of civil structures using RF antennas and ferroelectric sensors is presented. The sensors are fabricated with interdigital transducers printed on a piezoelectric polymer or ceramic type film. They in turn are mounted onto an ultra thin Penn State's novel RF antenna. The wave form measurements may be monitored at a remote location via the antennas in the sensors and an outside antenna.
