“…The researches on MXene-based sensors have shown a booming growth trend since its advent in 2015, according to the current reported articles, it is not difficult to find that most of MXene-based sensors are applied to intelligent wearable devices, working in the form of physical sensor (strain/pressure/piezoresistive sensor), regardless of 1D, 2D, and 3D MXene-based senor. 1D MXene-based fibers are commonly weaved into smart clothes for human health monitoring, besides this, it can be used for other special monitoring in other external stimuli such as working as the thermal sensor [196] MXene/ANFs aerogel Freeze-drying Pressure 128 kPa −1 0.01-623 kPa 320 [194] MXene/rGO aerogel Freeze-drying Pressure 22.56 kPa −1 0.01-3.5 kPa <200 [192] MXene/CSx aerogel Freeze-casting Pressure 80.4 kPa −1 0-5 kPa 109.6 [195] MXene sponge Dipping-coating Pressure/strain 442 kPa −1 0-18.56 kPa 138 [197] MXene sphere Ultrasonic spray pyrolysis NO 2 gas -5-100 ppm - [198] and optical fiber sensor.

“…However, it is easy to aggregate during drying process, which greatly decrease the specific surface area and lead to a worse gas sensing capability. To solve the problem, Yang et al fabricated a 3D crumpled MXene/ ZnO sphere (Figure 11h) by ultrasonic atomization, as a NO 2 gas sensor, it worked for room temperature application for the antiaggregation ability [198] (Figure 11g). Meanwhile, the obtained MXene-based sphere ensured large specific surface area and more activated adsorption sites were provided by combining ZnO nanoparticles with 3D folded MXene sphere.…”

“…Compared to signal MXene sheets or 3D folded MXene sphere, the response of MXene/ZnO sphere to 100 ppm NO 2 increased from 27.27% to 41.93%, and the recovery rate increased from 30% to ≈100%. [ 198 ] In all, the method made a great improvement on sensitivity, selectivity, responsiveness, and recovery capability for MXene‐based sensor, providing a valuable reference for the exploration of 3D MXene‐based gas sensing capability and application.…”

Moreover, a study from the World Health Organization (WHO) emphasized that death due to heart diseases and diabetes is still an upward trend and expected to be the first and seventh leading causes of death, respectively, by 2030. [16] Therefore, early diagnosis and treatment is urgently on demand. [12,17] A variety of human health-detection devices, intelligent wearable devices, and medical intelligent devices as efficient strategies have been emerging and making a big difference in daily life, [18][19][20][21][22][23] making it higher efficient, more accurate, more timely than traditional detection techniquesIn the meanwhile, sensors, as a vital component in intelligent detection devices quickly bloom to meet the requirement of high sensitivity, wide detection range, and stable response sensing capability. Sensors work through transforming external stimulus including biological, chemical, and physical changes into electrical signals changes. According to their respective work mechanism, sensors can be classified into the following several categories: piezoresistive, [24][25][26] piezoelectric, [27][28][29] frictional, [30] and capacitive. [31][32][33][34] Among them, piezoresistive sensors have attracted extensive concern for its simple structure, low cost, and easy signal acquisition, further being applied to the field of wearable detection devices. [35,36] It works by transforming external stimulus into visual electrical signals, and the change of resistance is generated by microscopic deformations of its own structure. [37][38][39][40] From sensors functional point of view, sensors can also be divided into strain sensors, [39,[41][42][43][44] stress sensors, [45,46] humidity sensors, [47] gas sensors, [41,48,49] temperature sensors, [50] and so on. On the present overall view, the key issue focuses on how to realize ideal sensors compatible with high sensitivity, wide detection range, ultralow response time, ultralow detection limitation, superb linearity, and cyclic stability. [51][52][53][54][55][56][57][58][59][60] What is noteworthy is that conductive materials interacting with other substances have been considered as an extremely efficient strategy to realize high sensing performance, being able to give out fast response reacting to outer tiny changes. Currently, aiming to endow sensors superb sensitivity and wide sensing range, flexible substrates for sensors commonly choose polydimethylsiloxane (PDMS), hydrogenated styrene-butadiene block copolymer (SEBS), and silicone rubber and other high elastic polymer materials. [37,57,61,62] Then, the composite sensor is fabricated successfully by different preparation techniques including With the advent of the era of intelligent manufacturing, sensors, with various detection objects, have set off a wave of enthusiasm and reached new heights in medical treatment, intelligent industry, daily life, and so on. MXene, as an emerging family of 2D transition metal carbides/nitrides, possesses impressive electrical conductivity, outstanding structural controllability, ...

In this work, we developed and optimized a cobalt oxide/tungsten oxide (Co3O4/WO3) p‐n heterojunction for NOx detection. Field emission scanning electron microscopy showed that the WO3 nanorods were embellished with Co3O4 nanostructure. X‐ray photoelectron spectroscopy revealed the presence of oxygen vacancy on the Co3O4 coupled with WO3 heterojunction. Compared to bare WO3 and pure Co3O4, the Co3O4/WO3 heterojunction sensor showed significant sensitivity to NOx at 200oC. The sensor exhibited higher linearity from 0.4 to 10 ppm of NOx, with a sensing response of 4.4% to 93%. The NOx sensitivity of the Co3O4/WO3 heterojunction sensor was 9‐fold higher than that of the pure WO3 sensor. Even at a high humidity (84%) environment, the Co3O4/WO3 heterojunction sensor demonstrated high NOx sensitivity. The sensor maintained remarkable stability measured for up to 4 weeks. We additionally discussed the possible NOx sensing mechanism of the Co3O4/WO3 heterojunction.This article is protected by copyright. All rights reserved.
