Abstract

Toxic gas emissions are a critical global health concern, responsible for numerous deaths each year. These hazardous gases can cause severe physiological reactions and even death upon exposure. To address this issue, we propose a graphene-Kapton-based flexible biosensor for non-invasive toxic gas detection. The sensor is designed to accurately detect and identify several harmful gases, including carbon monoxide (CO), fluorine azide (FN₃), hydrogen iodide (HI), nitrogen (N₂), methane (CH₄), nitrous oxide (N₂O), and ozone (O₃). Utilizing the Computer Simulation Technology (CST) Studio Suite 2024, we simulate the detection process, focusing on advanced techniques and miniature flexible structures. The sensor’s active element is a graphene patch embedded within a polyimide (Kapton) film, which allows for precise determination of the RF planar resonant structure’s frequency response. The graphene–Kapton biosensor is shown to have remarkable detection performance, as demonstrated by the results of the simulation, with a diffusivity of \({9.09e}^{-08}[{m}^{2}/S]\), an accuracy of \({6.62e}^{-13}\), and a power loss of \(1.5 mW\). These findings highlight the sensor’s potential as an effective tool for detecting and identifying toxic gases with high precision and efficiency.

期刊介绍： Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
