The evolutionary development of new engine materials and designs has allowed turbines to be operated at much higher temperature and achieve higher efficiencies, thus new materials have been developed to meet these new challenges. There is a growing need to assess the material behavior in these harsh environments so that structural models can be validated and engine components can be monitored during operation. This book demonstrated a ceramic strain sensor and temperature sensor based on reactively sputtered indium-tin-oxide (ITO) thin films have been developed to monitor the aerospace...
