The authors deduced strain analysis formulas of strain gauge models and attempted to fabricate strain gauges experimentally using a piezoelectric polymer film in this study. Constant cyclic load tests were carried out using semicircular-holed-notched test specimens and center-circular-holed-plate. Strains S_x and S_y are analyzed using the deduced strain formulas. As a result, the following conclusions are drawn. (1) As a result of analyzing the strain using piezoelectric polymer thin film strain gauges, it was shown that the strain analysis method used in this study is effective and the trial strain gauges can be used as an effective tool in an experiment. (2) The piezoelectric polymer film exhibits load frequency dependence. This dependence is a problem in strain measurements. Thus, the authors devised a method of improving this dependence.
