Polyvinylidene fluoride(an abbreviation PVDF ) generates.large output voltage, when the force is applied to a film. This property is called "piezoelectricity". This study was examined experimentally that the strain measurement is possible using piezoelectric polymer film. This study produces the gages using piezoelectric polymer. film and the experiments were carried out using this film.From the above fact, following results were obtained.(1) It was examined experimentally strain distribution good piezoelectric polymer film until now small. From the experimental result, the results of the accuracy were better than the conventional method.(2)Piezoelectric polymer films are produced process rolling. The output voltage of the film is different according to the rolling direction. In the case of the strain analysis, therefore, it superimposed a film to 2 directions, and strain gages were produced experimentally, the experiment was carried out further than before trial gages (5×5mm)The experimental result of strain distribution was obtained with the good accuracy.(3)Using the film that the electrode is being deposited only in one side of piezo-electric film, Strain distribution were measured using wide area (10×5mm) small area. (5×5mm) of these films. The accuracy was compared experimentally.It was verified that the accuracy is good from the comparison experiment in a small area film.

聚偏二氟乙烯（缩写PVDF）在对膜施加力时产生大的输出电压。这种性质被称为“压电性”。本研究通过实验验证了压电聚合物薄膜应变测量的可行性。本研究利用压电聚合物制作应变片。膜，并使用该膜进行实验。从上述事实，得到以下结果。(1)经实验检验，压电聚合物薄膜的应变分布良好，到现在为止还很小.从实验结果来看，该方法的准确性优于传统方法。（2）采用压延法制备压电聚合物薄膜。薄膜的输出电压根据滚动方向而不同。因此，在应变分析中，在两个方向上叠加了一个薄膜，并制作了应变片进行实验，实验比以前的试片（5×5mm）进行得更深入，得到了精度良好的应变分布实验结果。（3）采用在压电薄膜的一侧沉积电极的方法，在大面积（10×5mm）的小面积上测量应变分布。（5mm ×5mm）的电影。通过实验对测量精度进行了比较，在小面积薄膜上进行了对比实验，验证了测量精度良好。
