Experimental development of piezofilm modal sensors and characterization of piezofilm strain rate gages
Abstract
Piezoelectric film can be configured to sense specific modes of vibration. This paper presents results of experiments where shaped polyvinylidene fluoride (PVDF) film is used to sense vibration modes of a beam and a plate. Comparison of various dynamic test procedures shows that a PDVF film sensor gives more precise measurement of natural frequencies than accelerometers. Experiment results of the frequency response of PVDF used as strain rate gage are also presented.
