Parts-per-Trillion-Level Acetone Gas Detection Using a Suspended Graphene/SiO₂ SAW Breath and Skin Gas Sensor: Simulation and Experimental Study

ACS Sensors, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 13, 2025

Detection of parts-per-trillion (ppt)-level acetone gas molecules at room temperature using suspended graphene on SiO2 micropillars has rarely been achieved solid-state devices or surface acoustic wave (SAW) sensors. This paper presents the effect and as a guiding sensing layer to detect gas. The integration with introduces coupled resonance arising from interaction between mechanical vibrations micropillars. leads formation hybrid modes when natural frequencies align. coupling mechanism amplifies displacement energy Love propagating along sensor, enhancing its overall performance. Additionally, waves generates characteristic dips in transmission spectra. These correspond excitation specific flexural torsional within structure. A custom-fabricated SAW device, featuring diameter 4 μm heights 1.0 1.2 μm, demonstrated exceptionally high sensitivity toward concentration 500 ppt. Moreover, exhibited rapid response recovery times across wide range concentrations.

Mechanistic Insights and Interface Engineering in Bi₂O₃/Ti₃C₂T_X Nanohybrid for Enhanced CO₂ Sensor Performance

ECS Journal of Solid State Science and Technology, Journal Year: 2025, Volume and Issue: 14(4), P. 047008 - 047008

Published: April 1, 2025

Carbon dioxide emissions pose a significant threat to human health and the environment, necessitating improvements in CO 2 sensing devices. Current infrared detection sensors are complex large, limiting their practical applications due high-power consumption large size. To overcome this problem, we report herein -sensitive Bi O 3 /Ti C T x film based device fabricated using drop casting method. As-synthesized materials were analyzed for crystal structure size, surface morphology, composition XRD, SEM, EDS, UV-visible spectroscopy. The nanoparticles decorated on of Ti MXene sheets resulting formation nanocomposite. At room temperature, nanocomposite exhibits sensor response 1.43 at 250 ppm, which is better than pristine i.e. 1.35 same concentration ppm. When was exposed ppm , it exhibited recovery times 6.01 s 8.52 s, respectively. showed excellent selectivity good repeatability. This improvement junction interface nanocomposite, explained with detailed mechanism. These exceptional performances highlight potential gas applications.
