This report try to measure the dynamic strain applied cyclic load by using the piezo polymer film. Piezo polymer film has a property, which is no use amplifier to measure output voltage. So this research uses this to measure dynamic strain measurement. The experiments were carried out as follow ; piezo polymer film and strain gages are put on a test specimen and are applied dynamic cyclic load. The output voltage of a piezo polymer film are measured and compared to strain gage datas. An Experimental results are as follow. It is possible to measure the dynamic strain (applied cyclic load) by using piezo polymer film as well as strain gages.
