Flexible pressure sensors have attracted a lot of attention in fields such as medicine and healthcare due to their ease making wearable devices. However, the development flexible is facing challenges complex manufacturing process high cost. Herein, zinc oxide (ZnO) piezoelectric film sensor with 3 × array presented through an extremely simple ultralow‐cost fabrication reported. The series again, parallel. output voltage significantly higher compared original thin‐film at same thickness. ZnO...
A mechanistic study was presented on the effect of SiO2/Al2O3 ratio (SAR) adsorption/desorption behaviors low-concentration volatile organic compounds (VOCs) over H-ZSM-5. In this study, n-hexane, toluene, and ethyl acetate were used as probe VOC molecules. And their adsorption isotherms different H-ZSM-5 (SARs = 25, 130, 300, 470) collected at various temperatures (30, 40, 50 °C). Results showed that high SARs conducive to adsorption, but desorption efficiency imperfect. The dependence...
Aero-engine turbine stator blades are often used in harsh environments with high temperatures and pressure prone to fatigue fractures. Real-time accurate monitoring of blade surface stress strain is critical ensure safe operation. In this study, thin-film gauges (TFSGs) that can be high-temperature above 1000 °C were designed fabricated using a PtRh6 thin film as the sensitive material. The hysteresis effect transfer upon establishing thermo-mechanical coupling finite element model...
An accurate and continuous measurement of heat flux is needed in many long-term operation facilities order to monitor improve the life its machinery. A thin film sensor usually fabricated via sputtering, according different spatial arrangements thermocouple junctions. novel was designed, fabricated, calibrated, but connection between leads could not be fixed quickly steadily. For this purpose, paper a method seamlessly integrate has been proposed output signal. The capable simultaneously...
During the titanium alloy milling process, high temperatures in tool-chip contact area will affect tool life and precision of machining. Therefore, it is essential to measure temperature continuously. In this paper, a finite element simulation model process was established using ABAQUS2020 obtain highest location when alloy. The integration wire with alumina ceramic substrate formed an integrated substrate. Furthermore, NiCr, NiSi, SiO2 films were deposited on sequentially DC pulsed...
The chemical composition proportion of solid solution alloys in thermocouples (TCs) field is preliminarily explored by the cluster-plus-glue-atom (CPGA) model. CPGA clusters for face-centered cubic (fcc) and body-centered (bcc) structure elemental metal are established, which octahedron rhombic dodecahedron respectively. With introducing solute A element into solvent B matrix, atoms will prefer to certain sites cluster. Setting a cluster consisted as central cluster, Friedel oscillation...
Abstract Traditional thin-film thermocouples (TFTCs) have limitations in measuring real surface temperature changes aircraft because the connection between nanofilm and leads can easily fail. Despite this, how to improve this weak has rarely been addressed previous studies. In study, a lead-embedded alumina ceramic substrate is proposed durability of TFTCs. Multi-layer two-dimensional nanofilms with different electrode lengths were prepared on using DC-pulsed magnetron sputtering....
Conventional Langmuir probe techniques usually face the difficulty of being used in processing plasmas where dielectric compounds form, due to rapid failure by surface insulation. A solution problem, so-called harmonic technique, had been proposed and shown effectiveness. In this study, technique was investigated detail changing bias signal amplitudes V0, evaluated its accuracy comparing with conventional probe. It found that measured electron temperature Te increased but showing a...
