Conformal thin film sensing represents a cutting-edge technology capable of precisely measuring complex surface temperature fields under extreme conditions. However, fabricating high-temperature-resistant conformal thermocouple arrays remains challenging. This study reports method for manufacturing on metal spherical surfaces using printable paste composed silicates and Ag. Specifically, the use silicate glass phases enhances high-temperature performance silver paste, enabling ink coatings to withstand temperatures up 947 °C survive over 25 h at 900 °C. The thermocouples, connected Pt films, exhibited Seebeck coefficient approximately 17 μV/°C. As proof concept, an array six Ag/Pt thermocouples was successfully fabricated surface. Compared traditional wire-type more accurately reflect variations different points hold promise monitoring in harsh environments, such as aerospace nuclear energy applications.
