“…Moreover, the resistance drift rate at 800 °C was reduced by more than a factor of 4 after the encapsulation. Figure d,e exhibits the main performance criteria of recently reported strain gauges fabricated using DIW as a comparison. − ,− ,,− Notably, through the regulation of the Pd content and the deposition of a protective layer, the TCR and resistance drift rate decreased by factors of approximately 3 and 60, respectively, relative to our previously published AgPd-based strain gauges . These results highlight the combined advantages of the AgPd TFSG fabricated in this study with both low TCR and high thermal stability across a broad temperature range.…”

“…Therefore, these strain gauges have struggled to meet the demand for in situ strain monitoring of hot-end components. High-temperature thin/thick film strain gauges (TFSGs) have attracted attention recently due to their small size, fast response time, and easy integration with hot-end components. − Typical high-temperature resistant alloy materials, such as PdCr and PtRh, have been used as sensitive materials for TFSGs owing to their low temperature coefficient of resistance (TCR) and linear resistance–temperature curves . For instance, Liu et al have demonstrated a PdCr strain gauge based on the magnetron sputtering technique, with a TCR of 155.3 ppm/°C from room temperature to 800 °C .…”

A high-temperature thin/thick-film strain gauge (TFSG) shows development prospects for in situ strain monitoring of hot-end components due to their small perturbations, no damage, and fast response. Direct ink writing (DIW) 3D printing is an emerging and facile approach for the rapid fabrication of TFSG. However, TFSGs prepared based on 3D printing with both high thermal stability and low temperature coefficient of resistance (TCR) over a wide temperature range remain a great challenge. Here, we report a AgPd TFSG with a glass–ceramic protective layer based on DIW. By encapsulating the AgPd sensitive layer and regulating the Pd content, the AgPd TFSG demonstrated a low TCR (191.6 ppm/°C) from 50 to 800 °C and ultrahigh stability (with a resistance drift rate of 0.14%/h at 800 °C). Meanwhile, the achieved specifications for strain detection included a strain sensing range of ±500 με, fast response time of 153 ms, gauge factor of 0.75 at 800 °C, and high durability of >8000 cyclic loading tests. The AgPd TFSG effectively monitors strain in superalloys and can be directly deposited onto cylindrical surfaces, demonstrating the scalability of the presented approach. This work provides a strategy to develop TFSGs for in situ sensing of complex curved surfaces in harsh environments.
