“…Table 1 lists the response time of TFTCs measured by other groups. [21][22][23][24][25][26][27] From Table 1, it can be seen that without the memory hicorder, the response time of TFTCs could be reflected in the range of 10 0 -10 2 μs. Only with memory hicorder, the response time of TFTCs could be accurately reflected in the range of 10 1 -10 2 ns, because the memory hicorder could record TEF signal with microvolt and nanosecond accuracy, simultaneously.…”

“…[19,20] For example, with traditional voltmeter and oscilloscopes, many research teams reported the dynamic response time of TFTCs in several milliseconds. [21][22][23][24][25][26][27] So, without the accurate dynamic calibration procedure, TFTCs are restricted in some fields with quick response, such as aeronautics, space, nuclear energy, and so on. Fortunately, the memory hicorder could record TEF signal with microvolt and nanosecond accuracy, simultaneously.…”

In order to reveal the dynamic response characteristic of thin film thermocouples (TFTCs), the nichrome/nisil (NiCr/NiSi) TFTCs are prepared onto the glass substrate. With short pulse infrared laser system, NiCr/NiSi TFTCs are dynamically calibrated. The thermoelectric electromotive force (TEF) curves of NiCr/NiSi TFTCs are recorded by the memory hicorder system, which could reflect TEF signals with resolution ratio in nanosecond and microvolt, simultaneously. With increasing laser energy from 15.49 to 29.59 mJ, TEF curves display more and more violent oscillation, even negative value. The results show that the bounce of thermal energy happens between two interfaces of TFTCs because the thermal conductivity of glass and air is significantly lower than that of NiSi/NiCr TFTCs. The bounce of thermal energy results in the obvious decrease of nNiCr and nNiSi, as well as oscillation of TEF. For laser energy in 29.59 mJ, the bounce of thermal energy in NiCr film could result in nNiCr < nNiSi. Then, TEF value appears abnormal negative value. Based on the results, the complex thermal energy transport process in TFTCs dynamic calibration is revealed, which results in the oscillation of thermal energy and TEF signal.

“…In 2022, Cui used the magnetron sputtering technique for temperature measurement of rolling elements of bearings during vehicle operation, and deposited alumina thin films, NiCr thin films, NiSi thin films, and silica thin films on an aluminum alloy substrate successively. The fabricated thin film thermocouple has good linearity in the temperature range of 30~180 • C. The nonlinear fitting error of the sensor is less than 0.29% and the repeatability error is less than 4.55% [23].…”

To meet the need for micro-volume devices for high-precision measurement of temperature, Cu-Constantan (CuNi45) thin films with a novel array structure of thermo-electrodes were designed and fabricated. The thermo-electrodes on the probe-type substrate were deposited by magnetron sputtering technology and the profiling mask was prepared by 3D printing technology. The comprehensive performance of the temperature sensor was improved by systematic optimization of the heat treatment process and accuracy correction algorithm. Results showed that the sensor can measure with an accuracy of up to ±0.19%FS from −60 °C to 200 °C. The three-dimensional probe array temperature sensor shows great advantages in sensitivity, reliability resolution, stability, and measurement accuracy.

This paper deals with the problem of the influence of surface topography on the results of thermal diffusivity measurements when determined using the instantaneous surface heat source method, also called the pulse method. The analysis was based on numerical tests carried out using Comsol Multiphysics software. The results of experimental investigations on the actual material structure using an electron microscope, an optical microscope and a profilometer were used to develop a numerical model. The influence of the non-uniformity of the surface of the tested sample on the determined values of half-time of the thermal response of the sample’s rough surface to the impulse forcing on the opposing flat surface was determined by developing the data for simulated measurements. The effect of the position of the response data reading area on the obtained simulation results was also analyzed. The obtained results can be used to improve the accuracy of experimental heat transfer studies performed on thin-film engineering structures depending on the uniformity and parallelism of the material applied to engineering structures. The difference in half-life determination error results for various analyzed models can be as high as 16.7%, depending on the surface from which the responses of the heating impulse are read. With an equivalent model in which 10% of the material volume corresponds to the rough part as a single inclusion, hemisphere, the error in determining thermal diffusivity was equal to 3.8%. An increase in the number of inclusions with smaller weight reduces an error in the determination of thermal diffusivity, as presented in the paper.
