Low-grade heat (<100 °C) is abundant and ubiquitous in the environment, and the recovery of low-grade heat energy will be of great significance for the energy supply and the improvement of the environment. Low-cost and effective technologies for transforming low-grade heat into electricity are urgently needed. Thermocell (TEC) based on REDOX couples has become a promising technology for low-grade heat harvesting due to its advantages of low cost, scalability, and intrinsic high thermopower. To enhance its performance, different types of TECs need to incorporate various additives into the REDOX couples. However, there is currently no identical additive that effectively enhances the performance of both P-type and N-type TECs. In this paper, carboxylated chitosan is used as an identical additive, resulting in an increase in the Seebeck coefficient of P-type and N-type TECs by 115.33 % and 53.25 %, respectively. Furthermore, we introduce a novel sandwich-structured packing technique featuring a configuration of Metal/PET film/Carbon felt (MPC) for TEC. This approach effectively reduces both the cost and weight of the TEC, while the MPC structure further enhances their performance. The TEC can be scaled up to power electrical devices. Our achievement provides an effective strategy for harvesting low-grade heat energy.

Ultra-responsive single-crystal silicon MEMS thermopiles for differential thermal analysis (DTA) are developed. Facilitated by a unique “microholes interetch and sealing (MIS)” technique, pairs of suspended thermopiles are batch fabricated in a differential form, with high-density (54 pairs) n-type/p-type single-crystal silicon thermocouples integrated within each thermopile (sample area ~0.045 mm2). The fabricated MEMS thermopile sensors exhibit outstanding power responsivity of 99.5 V/W and temperature responsivity of 27.8 mV/°C, which are more than 4 times higher than those reported for material thermal analysis. The high-responsivity MEMS DTA chips allow us to accurately measure the indium melting point at different heating rates of ~1–100 °C/s. We also perform DTA measurement of the dehydration process of CuSO4·5H2O and the crystals show three stages of losing water of crystallization before becoming anhydrous copper sulfate salt. Our high-performance, cost-effective MEMS sensing chips hold promise for rapid and accurate DTA characterization for a wide range of applications.Keywords:MEMS thermopile;differential thermal analysis;DTA;single-crystal silicon thermocouples;MIS process

A new kind of thermocouple consisting of n-type and p-type semi-conductive oxides with a giant thermoelectric voltage is reported. The thermocouple was fabricated from n-type La0.8Sr0.2CrO3 and p-type In2O3 and it exhibits a high thermoelectric voltage of 410.3 mV at 1270 °C, which is the highest value reported for any type of thermocouples to date. This achievement challenges the long-established material selection principles for thermocouples and opens a new way for designing highly sensitive thermal sensors. The thermocouple developed in this work has great potential for practical applications in high temperature sensing in harsh environments.

Film thermocouples as the most effective tool are used to monitor the real-time and accurate in situ temperature in harsh environment, which will demand their electrodes with high thermal-resistant properties, high sensitivity, and stability. In this work, a series of solid solutions based on strontium lanthanum chromate were systematically investigated as new electrodes. LaCrO 3 and La 0.8 Sr 0.2 CrO 3 with some glass additives were chosen to fabricate high-performance thick-film thermocouple due to a bigger Fermi level difference between them. The thermocouple shows a high sensitivity (107.8 μV/°C) during static calibration, and an excellent reproducibility and stability during multicycle calibrations carried out up to 1550°C, resulting in a record ultra-high temperature sensing in film thermocouples. This facile thermocouple may open up a new way to measure high temperature in air or oxidation atmosphere accurately.

Thin film thermocouples (TFTCs) are known for their wide temperature measurement range and high precision, showing significant potential in aerospace and steel metallurgy applications. The lack of effective manufacturing techniques has been a major barrier to their mass production. Inkjet printing, a high-quality thin film additive manufacturing process operating outside vacuum environments, offers a viable solution for large-scale practical applications of TFTCs. We successfully fabricated ITO/In 2 O 3 high-temperature thin film thermocouples on ceramic substrates using inkjet printing technology. We developed a printable ink with excellent fluid characteristics, suitable for constructing the sensitive layer of the thermocouples. The fabricated sensors exhibited outstanding high-temperature stability and reliability, with a maximum measurement temperature exceeding 800 °C, surpassing the upper limits reported in other inkjet-printed temperature sensors. Continuous operation at 800 °C for 8 h resulted in a low drift rate of 1.53 °C/h. The sensors demonstrated 98.55 % high repeatability and 98.7%FS high accuracy across a wide temperature range, with a maximum Seebeck coefficient reaching 111 μV/°C, superior to most other high-temperature thin film sensors reported in literature. These findings show great potential in enhancing the safety of aerospace engineering equipment and ensuring the quality of products in the steel metallurgy industry.

La 1-x Sr x CrO 3 -In 2 O 3 thick film thermocouples were fabricated by screen-printing method for high temperature sensing and the effects of Sr 2+ content were investigated systematically. All La 1-x Sr x CrO 3 thick films showed well crystallization with orthorhombic unit cell. Their average particle sizes showed the tendency of first increase then decrease gradually with the increase of Sr 2+ content, and the maximum of average particle size was 1.76 μm. At the same time, the conductivities were improved with the increase of Sr 2+ content. The thermoelectric properties of La 1-x Sr x CrO 3 depended on the Sr 2+ content and the average Seebeck coefficients had an exponential decay tendency with the increase of Sr 2+ content. For La 1-x Sr x CrO 3 (x = 0.1–0.4)-In 2 O 3 thermocouples, excellent repeatability and stability were observed through multi-cycles and long-time usage testing at high temperature. The La 0.7 Sr 0.3 CrO 3 -In 2 O 3 thick film thermocouple with excellent thermal stability (drift rate: 0.81 °C/h) and reliability makes it become a promising candidate high sensitivity thermal sensor .

In₂O₃-IHFO (7 wt% hafnium-doped In₂O₃) thin-film thermocouples were fabricated on alumina substrates using pulsed laser deposition. A composite protective layer consisting of alumina and nano-silica was subsequently applied to enhance thermal stability. Cross-sectional analysis revealed a uniform, dense and well-defined film structure. Thermoelectric testing demonstrated that the protective layer effectively mitigates film volatilization at high temperatures, significantly enhancing thermocouple stability and performance at high temperatures. The maximum operating temperature reached 1550°C (hot junction), with excellent repeatability (≤2.4 %) in thermal cycling tests. The 9-hour high-temperature endurance test exhibits remarkable stability. These findings highlight a promising protective strategy for thin-film applications in extreme environments.

Ultra-high temperature thin-film sensors ( UTTSs ) offer advantages such as high sensitivity, rapid thermal response, and minimal environmental interference in multi-physical parameter monitoring of the hot sections. As one of the key parts of the UTTSs , the insulation films are of significance to their property and reliability to provide high temperature electrical isolation between workpiece and the sensitive film. However, the resistance of the insulation films will decrease at high temperatures, which causes the failure of the UTTSs . In this study, Al 2 O 3 composite films were fabricated using electrohydrodynamic jet (E-jet) printing technology combining Al 2 O 3 mixture and Al 2 O 3 sol. The S-Al 2 O 3 film prepared with the superior fluidity Al 2 O 3 sol can effectively repair the defect existing in the M-Al 2 O 3 film prepared with the Al 2 O 3 mixture. Consequently, it reduced the surface roughness of the insulation films from 1.496 μm to 1.086 μm and finally repaired their through defects. Experimental results demonstrated that the Al 2 O 3 composite films exhibited significantly improved performance compared to pure M-Al 2 O 3 . The insulation resistances can reach up to 25 MΩ, 199 kΩ at 800 °C and 1200 °C, respectively. The normalized resistance of the Al 2 O 3 composite films is up to 476 times higher than that in the existing literatures at 800 °C. Practically, the Al 2 O 3 composite films were applied to the thin-film strain gauges ( TFSGs ) and the tungsten-rhenium coaxial thermocouples ( TRCTs ). Both of the TFSGs and the TRCTs exhibited excellent performance at high temperatures.

Plasma catalytic reverse water-gas shift (RWGS) reaction is considered efficiently to convert CO 2 into CO for the synergistic effect between plasma and catalyst. However, this synergistic effect has long not been properly evaluated, due to the difficulty in measuring the actual catalyst temperature ( T cat ) during discharge. Herein, we report a novel foam electrode structure plasma catalytic reactor that enables real-time measurement of the central temperature ( T C ) of the foam electrode by a thermocouple during discharge. Since the catalyst is coated onto the foam electrode, T C is much closer to T cat than the commonly used wall temperature ( T W ). Based on T C , a proper evaluation of the synergistic effect is conducted by employing a synergy factor ( SF ) within 196 o C–390 o C. It is found that CO 2 conversion in plasma-catalysis is not only higher than the sum of that in plasma and thermal-catalysis individually, but also breaks the thermodynamic equilibrium limitation. Moreover, this novel reactor exhibits higher CO 2 conversion (30.0 %) for RWGS reaction compared to that in a typical packed-bed plasma catalytic reactor (19.6 %) with a same discharge power of 16.5 W and gas hourly space velocity of 12000 ml/(g·h), demonstrating its potential in the application of RWGS process.
