“…A material with a large surface area is favorable for selectively adsorbing gas molecules, can effectively transform gas information into a detection signal, and has excellent mechanical properties. [19] OSCs are commonly used as active layers in gas sensors, and charge transport between molecules is accomplished through conjugated π bonds. Depending on their molecular architectures, OSCs can be categorized as either polymers or small molecules.…”

Over the past several years, a variety of hardware-based artificial sensory systems, including artificial skin, electronic noses, and artificial retinas, have attracted considerable research interest in advanced artificial intelligence systems. The integration of sensing and computing functions in single or multiple connected self-adaptive field-effect transistor (FET)-structured sensory devices to implement artificial olfactory systems for in-sensor computing has recently attracted increasing attention. In this review, the development status of FET-based gas sensory devices is focused on. The mechanisms of sensory FET devices, gas-recognition materials, strategies for improving sensing performance, and the integration of sensory devices into the artificial olfactory system are discussed. Finally, the further development of FET-based sensory devices for artificial olfactory systems and their great potential for next-generation intelligent sensory systems are discussed in broad fields such as environmental monitoring, health care, and military industries.

With the rapid growth of emerging point-of-use (POU)/point-of-care (POC) detection technologies, miniaturized sensors for the real-time detection of gases and airborne pathogens have become essential to fight pollution, emerging contaminants, and pandemics. However, the low-cost development of miniaturized gas sensors without compromising selectivity, sensitivity, and response time remains challenging. Microfluidics is a promising technology that has been exploited for decades to overcome such limitations, making it an excellent candidate for POU/POC. However, microfluidic-based gas sensors remain a nascent field. In this review, the evolution of microfluidic gas sensors from basic electronic techniques to more advanced optical techniques such as surface-enhanced Raman spectroscopy to detect analytes is documented in detail. This paper focuses on the various detection methodologies used in microfluidic-based devices for detecting gases and airborne pathogens. Non-continuous microfluidic devices such as bubble/droplet-based microfluidics technology that have been employed to detect gases and airborne pathogens are also discussed. The selectivity, sensitivity, advantages/disadvantages vis-a-vis response time, and fabrication costs for all the microfluidic sensors are tabulated. The microfluidic sensors are grouped based on the target moiety, such as air pollutants such as carbon monoxide and nitrogen oxides, and airborne pathogens such as E. coli and SARS-CoV-2. The possible application scenarios for the various microfluidic devices are critically examined.

“…Recently, 1D and 2D nanomaterials have been also recognized as very promising for gas sensing applications. [ 19–31 ] Compared to the bulk, powder, and microstructure counterparts, 1D and 2D nanomaterials have smaller size, larger surface‐to‐volume ratio, and higher aspect‐ratio, enabling a stronger interaction (in some cases of each atom, e.g., in single‐walled CNTs and single layer 2D materials) of the material with the target gas. These features increase adsorption of gas molecules per unit of volume, accelerate the sensing process, reduce response time, and improve sensitivity, at the same time reducing the sensor size, improving integration level, decreasing power dissipation, and lowering cost per device.…”

Rapid progress in the synthesis and fundamental understanding of 1D and 2D materials have solicited the incorporation of these nanomaterials into sensor architectures, especially field effect transistors (FETs), for the monitoring of gas and vapor in environmental, food quality, and healthcare applications. Yet, several challenges have remained unaddressed toward the fabrication of 1D and 2D FET gas sensors for real‐field applications, which are related to properties, synthesis, and integration of 1D and 2D materials into the transistor architecture. This review paper encompasses the whole assortment of 1D—i.e., metal oxide semiconductors (MOXs), silicon nanowires (SiNWs), carbon nanotubes (CNTs)—and 2D—i.e., graphene, transition metal dichalcogenides (TMD), phosphorene—materials used in FET gas sensors, critically dissecting how the material synthesis, surface functionalization, and transistor fabrication impact on electrical versus sensing properties of these devices. Eventually, pros and cons of 1D and 2D FETs for gas and vapor sensing applications are discussed, pointing out weakness and highlighting future directions.
