ConspectusGas sensors are used in various applications to sense toxic gases, mainly for enhanced safety. Resistive particularly popular owing their ability detect trace amounts of high stability, fast response times, and affordability. Semiconducting metal oxides commonly employed the fabrication resistive gas sensors. However, these often require working temperatures, bringing about increased energy consumption reduced selectivity. Furthermore, they do not have enough flexibility, performance is significantly decreased under bending, stretching, or twisting. To address challenges, alternative materials capable operating at lower temperatures with flexibility needed. Two-dimensional (2D) such as MXenes transition-metal dichalcogenides (TMDs) offer surface area conductivity unique 2D structure, making them promising candidates realization Nevertheless, sensing pristine form typically weak unacceptable, terms response, selectivity, recovery time (

Wearable gas sensors have drawn great attention for potential applications in health monitoring, minienvironment detection, and advanced soft electronic noses. However, it still remains a challenge to simultaneously achieve excellent flexibility, high sensitivity, robustness, permeability, because of the inherent limitation widely used traditional organic flexible substrates. Herein, an electrospinning polyacrylonitrile (PAN) nanofiber network was designed as substrate, on which ultraflexible wearable sensor prepared with situ assembled polyaniline (PANI) multiwalled carbon nanotubes (MWCNTs) sensitive layer. The unique strong binding force between substrate sensing materials endow permeability. can maintain stable NH3 performance while sustaining extreme bending stretching (50% strain). Young's modulus PAN/MWCNTs/PANI is low 18.9 MPa, several orders magnitude smaller than those reported sensors. water vapor transmission rate 0.38 g/(cm2 24 h), enables wearing comfort sensor. Most importantly, due effective exposure sites well heterostructure effect MWCNTs PANI, shows sensitivity at room temperature, theoretical limit detection 300 ppb. This work provides new avenue realization reliable high-performance

A composite of sulfur nanosheets (S-NSs) with hydrophobic carbon nanotubes (H-CNTs) was designed, and a chemiresistive gas sensor based on this material constructed for breath analysis NH3 detection at room temperature. Taking advantage the capillary condensation CNTs, effect hexadecyltrimethoxysilane (HDTMS), high sensitivity S-NSs to detection, showed an improved humidity-resistant capacity is capable detecting breath-relevant concentrations down ppb level under humidity. The fabricated exhibited fast response/recovery (18/26 s) good stability. Online monitoring exhaled shows recovery stable baseline, providing potential practical application. research also facilitates development commercial low-cost sensors.
