Abstract
The various sensors development to quantify the deterioration of brittle structures for structural health monitoring is on the rise now. In this paper, strain measurement using the piezoelectric of the PVDF film is paid attention. An experimental confirmation of PVDF film's sensing performance is done by the comparison with traditional strain gauge sensor. To use this PVDF film as a crack detection sensor, first the crack progress on aluminum specimen were monitored and measured. Then the PVDF film sensors were used to monitor the generation and propagation on cracks due to progressive application of loads on RC beams in the laboratory. These film sensors were able to identify the appearance and propagation of cracks better than those of traditional strain gauge sensors.
