In high-temperature applications, it is difficult to get accurate temperature measurements in a closed system in operando conditions. High-temperature, application-specific thermistors and thermocouples are printed using semiconductive oxide-based inks and Direct Ink Writing (DIW) to form multilayer custom sensor pathways that are embedded in components for high-temperature applications. Print process mapping and rheology measurements are utilized to determine parameter selection for ink formulation based on composition and viscosity. Additionally, this print mapping will aid in parameter selection for DIW based on printing pressure, speed, nozzle size, and substrate printed upon. Statistical analysis of the print mapping, spreading behavior, and drying rate is conducted to determine consistency metrics, ideal parameters for additive manufacture of these sensors, and ideal ink formulation for semiconductive oxide-based inks. This work will lead to future advances in DIW of these oxides and other ceramics in the future.
