“…Flexible electronics holds a prominent position and is expected to meet emerging technological demands and unprecedented applications compared to rigid electronics devices [1,2]. Particularly, the manufacture of flexible gas sensors based on metal oxide thin film presents an interesting perspective for progress in many fields such as the monitoring of atmospheric environment, the detection of hazardous gases [3,4] and smart food packaging [5]. However, it is subject to restrictions requiring high operating temperatures which are not compatible with plastic foils.…”

The fabrication of printed electronic devices based on metal oxide inks requires the formulation of stable suspensions with specific fluidic properties. In our work, a tin oxide based solution was synthetized by aqueous sol-gel method, and transformed into an ink with appropriate viscosity and surface tension to be inkjet-printed on polyimide foil and sintered at relatively low temperature. Thermal analysis by TGA/DSC and microstructural analysis by XRD of synthetized sol show that a crystallized structure of SnO2 could be obtained at 350°C, which is lower than crystallization temperatures of SnO2 previously reported in the literature, and entirely consistent with the use of polyimide foil. The stability and the rheological properties of the ink were studied to ensure the jettability criteria of the inkjet-printer. Electrical measurements of the printed sensing films were performed to characterize the response to CO gas in different concentrations, at working temperature of 300°C.

“…On this way, A.S.M.I. Uddin et al [47] obtained an acetylene (C 2 H 2 ) gas sensor consisting of Ag-loaded ZnO nanorods, supported by a polyimide/polytetrafluoroethylene substrate, which exhibited a high response magnitude of 27.2 (at 1000 ppm) with worse response and recovery times (62 and 39 s, respectively), compared to ours, while Galstyan et al [48] reported the fabrication and sensing properties of ZnO nanostructures, which exhibited relative good sensitivity towards NO 2 , H 2 , and CH 4 gases, at higher working temperatures (0.37 @ 300 1C, 11.26 @ 400 1C, and 0.1 @ 500 1C, respectively). In addition, Narimani et al [49] reported the fabrication and characterization of high sensitivity capacitive humidity sensors based on ZnO nanorods grown by means of chemical bath deposition, which demonstrated an extremely long transient time until the result saturates to its final capacity value.…”

Good quality ZnO nanostructures were obtained by the microwave-assisted hydrothermal synthesis, at low reaction temperatures, using zinc acetate as the starting precursor. X-ray diffraction confirmed the crystallinity of the ZnO nanostructures, which resulted free of impurities. Field emission gun scanning electron microscopy analysis revealed that the ZnO nanostructures crystallized at 120 1C were more homogeneous and had a constant diameter along the entire wire length, exhibiting an ideal defect density that favors the gas sensing response. A new ozone gas sensor based on these nanostructures was evaluated at low exposure times (15 s) by recording the change in the film resistance. The ZnO nanostructures showed good sensitivity even at low ozone concentration (100 ppb), and fast response and short recovery time at 200 1C, demonstrating great potential for a variety of applications. Two main effects were observed: the first one is intrinsic to that of the sample, while the second is a consequence of the surface and interface complex cluster defects, which produce extrinsic defects.

“…It was said that a very low power for their operations (<6 mW) was achieved in their design. The other research group carried out similar researches using different materials, such as Tungsten trioxide (WO 3 ), and Zinc ferrite (ZnFe 2 O 4 ) for various MEMS gas sensors [79][80][81]. However, the weakness of those materials was that the heat source is needed in their MEMS platform.…”

With the fast development of the fifth-generation cellular network technology (5G), the future sensors and microelectromechanical systems (MEMS)/nanoelectromechanical systems (NEMS) are presenting a more and more critical role to provide information in our daily life. This review paper introduces the development trends and perspectives of the future sensors and MEMS/NEMS. Starting from the issues of the MEMS fabrication, we introduced typical MEMS sensors for their applications in the Internet of Things (IoTs), such as MEMS physical sensor, MEMS acoustic sensor, and MEMS gas sensor. Toward the trends in intelligence and less power consumption, MEMS components including MEMS/NEMS switch, piezoelectric micromachined ultrasonic transducer (PMUT), and MEMS energy harvesting were investigated to assist the future sensors, such as event-based or almost zero-power. Furthermore, MEMS rigid substrate toward NEMS flexible-based for flexibility and interface was discussed as another important development trend for next-generation wearable or multi-functional sensors. Around the issues about the big data and human-machine realization for human beings’ manipulation, artificial intelligence (AI) and virtual reality (VR) technologies were finally realized using sensor nodes and its wave identification as future trends for various scenarios.
