The principle and the method of dynamic strain measurement with PVDF piezoelectric film were investigated. The straincharge constants of two PVDF strain gauges were calibrated with a unidirectional strain block. The strain waves in a uniaxial stress bar were measured with these gauges. Experimental results of good precision were obtained.
