“…The NO 2 interaction with the rGO flakes leads to a decrease of the device resistance, that is, a p-type behaviour. Another stretchable rGO-based conductometric gas sensor has been fabricated and tested in standard conditions, differently from the previous one, which has been tested only in chambers with controlled environment [ 118 ]. The hydrazine-reduced rGO have been deposited on a polyurethane nanofibres.…”

After the synthesis of graphene, in the first year of this century, a wide research field on two-dimensional materials opens. 2D materials are characterized by an intrinsic high surface to volume ratio, due to their heights of few atoms, and, differently from graphene, which is a semimetal with zero or near zero bandgap, they usually have a semiconductive nature. These two characteristics make them promising candidate for a new generation of gas sensing devices. Graphene oxide, being an intermediate product of graphene fabrication, has been the first graphene-like material studied and used to detect target gases, followed by MoS2, in the first years of 2010s. Along with MoS2, which is now experiencing a new birth, after its use as a lubricant, other sulfides and selenides (like WS2, WSe2, MoSe2, etc.) have been used for the fabrication of nanoelectronic devices and for gas sensing applications. All these materials show a bandgap, tunable with the number of layers. On the other hand, 2D materials constituted by one atomic species have been synthetized, like phosphorene (one layer of black phosphorous), germanene (one atom thick layer of germanium) and silicone (one atom thick layer of silicon). In this paper, a comprehensive review of 2D materials-based gas sensor is reported, mainly focused on the recent developments of graphene oxide, exfoliated MoS2 and WS2 and phosphorene, for gas detection applications. We will report on their use as sensitive materials for conductometric, capacitive and optical gas sensors, the state of the art and future perspectives.

In the era of the Internet of Things, wearable technologies are expected to become an indispensable part of daily life. In recent times, highly sensitive, flexible, and stretchable electronic gas sensors are gaining tremendous interest due to their applicability in wearable electronics applications. The construction of wearable gas sensors are reviewed for real‐time, highly sensitive, and selective detection of hazardous gases at room temperature (RT) that can be laminated onto a human body or integrated with body‐worn textile or other consumer products, utilizing carbon nanomaterials, conductive polymers, 2D nanostructured materials, and their composites. Sensing materials, transduction techniques, and substrates for high‐performance wearable gas sensing are discussed in detail. The critical challenges for future development of wearable gas sensors are presented. Wearable gas sensors are believed to have great potential in environmental monitoring, healthcare, public safety, security, as well as food quality monitoring.

“…The development of a transparent sensor can meet specific needs and develop more extensive applications. At present, the research studies of transparent sensors mainly include chemical sensors that detect and monitor dangerous substances in the gas phase, protecting us from pollution and toxic gases [ 133 ]. Self-powered sensors convert wasted micromechanical energy into available electrical energy based on the principles of triboelectricity and piezoelectric [ 134 , 135 , 136 ].…”

“…Duy et al [ 133 ] prepared the elastic polyurethane electrospun nanofibrous multilayer sensor with chemical response, which was flexible and stretchable, by electrospun PU nanofibers and reductive polyethylene oxide (R-GO) by self-assembly (LBL), which was used for gas or steam detection. The R-GO/PU devices with four and five layers have excellent sensitivity and mechanical sustainability up to 50% of the strain under static and cyclic tensile tests.…”

The optically transparent electrospun fibrous membrane has been widely used in many fields due to its simple operation, flexible design, controllable structure, high specific surface area, high porosity, and unique excellent optical properties. This paper comprehensively summarizes the preparation methods and applications of an electrospun optically transparent fibrous membrane in view of the selection of raw materials and structure modulation during preparation. We start by the factors that affect transmittance among different materials and explain the light transmission mechanism of the fibrous membrane. This paper also provides an overview of the methods to fabricate a transparent nanofibrous membrane based on the electrospinning technology including direct electrospinning, solution treatment after electrospinning, heat treatment after electrospinning, and surface modification after electrospinning. It further summarizes the differences in the processes and mechanisms between different transparent fibrous membranes prepared by different methods. Additionally, we study the utilization of transparent as-spun membranes as flexible functional materials, namely alcohol dipstick, air purification, self-cleaning materials, biomedicine, sensors, energy and optoelectronics, oil–water separation, food packaging, anti-icing coating, and anti-corrosion materials. It demonstrates the high transparency of the nanofibers’ effects on the applications as well as upgrades the product performance.
