“…Their ability to prevent the sensor pollution improve the device’s long-term stability and anti-noise ability. The detection accuracy is also significantly better than that of traditional gas sensors and even the detection of single gas molecules has been widely studied [ 160 , 161 , 162 , 163 , 164 ]. The gas chemosensors, based on the carbon nanotube field-effect transistor in recent years are summarized in Table 3 .…”

Nano biochemical sensors play an important role in detecting the biomarkers related to human diseases, and carbon nanotubes (CNTs) have become an important factor in promoting the vigorous development of this field due to their special structure and excellent electronic properties. This paper focuses on applying carbon nanotube field-effect transistor (CNT-FET) biochemical sensors to detect biomarkers. Firstly, the preparation method, physical and electronic properties and functional modification of CNTs are introduced. Then, the configuration and sensing mechanism of CNT-FETs are introduced. Finally, the latest progress in detecting nucleic acids, proteins, cells, gases and ions based on CNT-FET sensors is summarized.

“…To this end, self-powered gas sensors have recently been proposed by integrating or coupling nanogenerators based on the triboelectric effect, photovoltaic (PV) effect, and thermoelectric effect with the sensor. [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] For example, Sun et al have proposed a self-powered NO 2 sensor driven directly by triboelectric nanogenerators (TENG) instead of traditional power supply. [34] Su and co-workers have tactfully developed Alveolus-inspired active membrane sensors based on the triboelectric effect for self-powered chemical sensing.…”

Flexible gas sensors play an indispensable role in diverse applications spanning from environmental monitoring to portable medical electronics. Full wearable gas monitoring system requires the collaborative support of high‐performance sensors and miniaturized circuit module, whereas the realization of low power consumption and sustainable measurement is challenging. Here, a self‐powered and reusable all‐in‐one NO2 sensor is proposed by structurally and functionally coupling the sensor to the battery, with ultrahigh sensitivity (1.92%/ppb), linearity (R2 = 0.999), ultralow theoretical detection limit (0.1 ppb), and humidity immunity. This can be attributed to the regulation of the gas reaction route at the molecular level. The addition of amphiphilic zinc trifluoromethanesulfonate (Zn(OTf)2) enables the H2O‐poor inner Helmholtz layer to be constructed at the electrode–gel interface, thereby facilitating the direct charge transfer process of NO2 here. The device is then combined with a well‐designed miniaturized low‐power circuit module with signal conditioning, processing and wireless transmission functions, which can be used as wearable electronics to realize early and remote warning of gas leakage. This study demonstrates a promising way to design a self‐powered, sustainable, and flexible gas sensor with high performance and its corresponding wireless sensing system, providing new insight into the all‐in‐one system of gas detection.

In this work, a selective and highly sensitive gas sensor using tungsten oxide (WO 3 ) nanofibers was fabricated via electrospinning. WO 3 was functionalized with gold nanoparticles by magnetron sputtering at different sputtering times to obtain Au films with thicknesses of 1, 5, 10, and 15 nm. The sensing performance of Au film composite nanomaterials with different Au layer thicknesses was tested at 100−250 °C and different nitrogen dioxide (NO 2 ) concentrations ranging from 200 to 1000 ppb. The findings showed that the 10 nm Au−WO 3 composite nanomaterial sensor had the most significant improvement in the performance of the pristine WO 3 sensor compared with other Au−WO 3 composite nanomaterial sensors, and the optimal operating temperature of the sensor was 175 °C. The composite nanomaterial sensor exhibited excellent selectivity when exposed to different gases and also exhibited high sensibility when exposed to low concentrations of NO 2 under high humidity (80%). The mechanism of gas sensor performance improvement was also investigated.
