“…Temperature monitoring of hot-end components in extreme environments is vital in the field of aircraft engines. − For example, rapid and accurate measurement of the real-time temperature of turbine blades or spindle bearings contributes to the structural optimization and early fault diagnosis of critical components . Traditional wire temperature detectors, embedded sensors, welded sensors, and noncontact optical sensors have difficulties producing nondestructive and in situ temperature measurements of operating parts such as rotary blades or bearings. − Thin-film temperature sensors with rapid response, small disturbance, and easy integration are desired for the temperature measurement of hot-end components in harsh environments. − Platinum (Pt), with its relatively high melting point (1773 °C) and excellent chemical inertness, is a viable material for use in high temperature sensing. , The most commonly used manufacturing techniques for Pt films are screen printing, electron lithography, and magnetron sputtering .

In situ temperature monitoring of curved high-temperature components in extreme environments is challenging for a variety of applications in fields such as aero engines and gas turbines. Recently, extrusion-based direct ink writing (DIW) has been utilized to fabricate platinum (Pt) resistance temperature detectors (RTDs). However, the current Pt RTD prepared by DIW technology suffers from a limited temperature range and poor high-temperature stability. Here, DIW technology and yttria-stabilized zirconia (YSZ)-modified precursor ceramic film packaging have been used to build a Pt RTD with high-temperature resistance, small disturbance, and high stability. The results indicate that the protective layer formed by the liquid phase anchors the Pt particles and reduces the agglomeration and volatilization of the Pt sensitive layer at high temperature. Attributed to the SiCN/YSZ protective layer, the temperature resistance curve of the Pt RTD in the range of 50–800 °C has little deviation from the fitting curve, and the fitting correlation coefficient is above 0.9999. Interestingly, the Pt RTD also has high repeatability and stability. The high temperature resistance drift rate is only 0.05%/h after 100 h of long-term testing at 800 °C and can withstand butane flame up to ∼1300 °C without damage. Moreover, the Pt RTD can be conformally deposited on the outer ring of aerospace bearings by DIW technology and then realize on-site, nondestructive, and real-time monitoring of bearing temperature. The fabricated Pt RTD shows great potential for high-temperature applications, and the novel technology proposed provides a feasible pathway for temperature monitoring of aeroengine internal curved hot-end components.

“…But the thickfilm Pt sensor is not good at picking up weak heat signals because of its large heat capacity caused by the large volume. Some other researchers used thin-film Pt resistance as temperature sensors with the thickness in a range of tens to hundreds nanometers [21,22]. These showed a better response for weak signals, despite sacrificing some temperature sensitivity [23].…”

Energy transformation, which can be described as temperature variations, is present in all activities of cellular metabolism. Detecting the temperature of numerous cells over the course of their lives is useful for studying the cellular physiological function and investigating the pathophysiology of illnesses. Current cell thermometric technologies, such as luminous temperature sensors, infrared thermometers, and thermocouple thermometers, have their own limitations, such as complicated operation, low repeatability, and inability to measure cell temperature in normal situations. Here, we have developed a high-precision platinum temperature sensor with small heat capacity, good heat conduction, excellent stability and biological compatibility, which made it possible to sense cells heat signal. The platinum resistance sensor’s temperature coefficient of resistance (TCR) was around 2800ppm/°C, with a good linear correlation (R2＞0.999) between resistance and temperature from 35 °C to 43 °C. The noise of the sensor system was below 0.02 °C, giving a small and stability noise in detection. The detecting cells were CHO-K1 cells. They caused a temperature increase of about 0.075 °C, which is higher than the sensor without cells. This platinum sensor has been found to be useful for in situ temperature measurement of cells, which is important for investigating cell informatics and pathology.

The paper discusses evaluation of machining solutions for oversized thin-walled robotic portal component for conveyance workplaces. The following portal CNC machining centers have been selected. Firstly, a FSGC 300 "portal type" portal was proposed, with a 50000 mm "X" axis and Heidenhain control system, the second portal was a DMU 340 portal with the maximum axis "X" of 6000 mm and Siemens Sinumerik control system and the last portal was the VF-10 / 40 one, with the maximum axis "X" of 3048 mm and Fanuc control system. Further, the method of fixing a thin-walled robotic portal is designed and individual options are evaluated for their economy. The CAM software application used for programming the production was SolidWorks.
