Outline
With the advancement of high-performance aero-engines and the growing future requirements for intelligent engine design， monitoring the strain of critical components subjected to combined thermal and mechanical stresses has evolved as a vital data source. This data is essential for evaluating material performance during service， enhancing design accuracy， and achieving comprehensive lifecycle management.Indium tin oxide （ITO） thin films have emerged as a preferred material for measuring high-temperature strain in structural materials due to their stability at elevated temperatures，excellent strain measurement sensitivity，and excellent electrical conductivity. This paper expounds on the fundamental principles，basic structures，and preparation methods of resistive thin-film strain gauges，and analyzes and investigates strategies for enhancing the performance of ITO resistive thin film strain gauges，thereby promoting their engineering applications in the aerospace industry.
