“…To address this issue, probe-type TFTCs were developed. Electrode films were prepared on the side and end face of the cylinder, on which they formed a thermal node for temperature measurement [42]. The probe-type TFTCs did not affect the thermal fluids pattern, low temperature of the cold end, and high measurement accuracy (figure 1(b)) [37,43].…”

High-temperature thin-film thermocouples (TFTCs) have garnered significant attention in aerospace and steel metallurgy industries. However, previous studies on TFTCs have primarily focused on the two-dimensional planar type, whose thermal sensitive area has to be perpendicular to the test environment, and therefore affects the thermal fluids pattern or loses the accuracy. In order to address this problem, recent studies have developed the three-dimensional probe-type TFTCs, which can be set parallelly to the test environment. Nevertheless, the probe-type TFTCs are limited by their measurement threshold and poor stability at high-temperature. To address these issues, in this study, we propose a novel probe-type TFTCs temperature sensor with a sandwich structure. The sensitive layer is compounded with indium oxide (In2O3) doped zinc oxide (ZnO) and fabricated using screen-printing technology. With the protection of sandwich structure on electrode film, the sensor demonstrates robust high-temperature stability, enabling continuous working at 1200 °C above 5 hours with a low drift rate of 2.3 °C/h. This sensor exhibits a high repeatability of 99.3% when measures the low to high temperatures, which is beyond the most existing probe-type TFTCs reported in the literature. With its excellent high-temperature performance, this temperature sensor holds immense potential for enhancing equipment safety in the aerospace engineering and ensuring product quality in steel metallurgy industries.

“…In addition, the temperature of the inner wall of an aircraft is a key parameter for characterizing supersonic combustion. To perform high-temperature measurements [3,4], various thermal sensors (e.g., thermocouples, optical pyrometers, acoustic pyrometers, and thermal resistance sensors) have been developed. However, these thermal sensors are affected by several issues.…”

In this study, thin-film thermocouples (TFTCs) were combined with a smart bolt to design a smart bolt that can directly test high temperature in service monitoring and parameter calculation for gas turbine structure design. The first-principles calculation was used to analyze the design of the surface properties of nickel-based alloys and insulating layers, and finite element analysis was used to optimize dimension parameters by controlling the thermal stress matching of insulating layers and sensitive layers. The effect of the glass powder with different particle sizes on the microstructure of the ITO and In2O3 films was studied via SEM. The preferred particle size of the additive glass powder is 400 nm. The XRD pattern shows the (222) peak has the highest intensity. The intensities of the (222) and (622) peaks increase after the heat treatment. The calibration results show that the average Seebeck coefficient of the TFTCs can reach 64.9 μV/°C at 1100 °C with a maximum voltage of 71.4 mV. The repeatability error of the cycles of the sensor after heat treatment is ±1.05%. The repeatability of the sensor is up to 98.95%. The smart bolts were tested for application in small aero engines. It can be seen that under the impact of 1000 °C, the thermal response of the prepared smart bolt is better than that of the K-type armored thermocouple, and the thermal balance is achieved faster. The intelligent bolt sensor proposed in this work has better engineering application prospects owing to its convenience of installation in harsh environments.
