Polymer films are used for a substrate of flexible electronic devices. Such substrates are required to be durable against cyclic bending. Therefore, predicting fatigue life of bending polymer films enables us to design an appropriate polymer substrate. However, a huge number of experiments are required to predict the fatigue life by a conventional method. In this study, we predicted the fatigue life of bending polymer films by machine learning.
