“…Ammonia is a toxic gas, hazardous to human health; therefore, its monitoring by sensors is very important. A general introduction to ammonia gas, its sources, and detection at low concentrations of parts per billion (ppb) in air is summarized by Timmer et al Different nanostructured materials including carbon nanotubes, ,− polyaniline, polypyrrole, − ZnO, − tungsten trioxide (WO3), , SnO 2 , , TiO 2 , α-Fe 2 O 3 , vanadium oxide, , transition metal dichalcogenides, , and graphene, − have been investigated for ultralow-level detection of NH 3 . Wang et al chemically reduced GO sheets on Au electrodes to rGO sheets by hydrazine or pyrrole vapors, which consequently provided a gas sensor based on self-assembled rGO sheets.…”

Wearable electronics is expected to be one of the most active research areas in the next decade; therefore, nanomaterials possessing high carrier mobility, optical transparency, mechanical robustness and flexibility, lightweight, and environmental stability will be in immense demand. Graphene is one of the nanomaterials that fulfill all these requirements, along with other inherently unique properties and convenience to fabricate into different morphological nanostructures, from atomically thin single layers to nanoribbons. Graphene-based materials have also been investigated in sensor technologies, from chemical sensing to detection of cancer biomarkers. The progress of graphene-based flexible gas and chemical sensors in terms of material preparation, sensor fabrication, and their performance are reviewed here. The article provides a brief introduction to graphene-based materials and their potential applications in flexible and stretchable wearable electronic devices. The role of graphene in fabricating flexible gas sensors for the detection of various hazardous gases, including nitrogen dioxide (NO), ammonia (NH), hydrogen (H), hydrogen sulfide (HS), carbon dioxide (CO), sulfur dioxide (SO), and humidity in wearable technology, is discussed. In addition, applications of graphene-based materials are also summarized in detecting toxic heavy metal ions (Cd, Hg, Pb, Cr, Fe, Ni, Co, Cu, Ag), and volatile organic compounds (VOCs) including nitrobenzene, toluene, acetone, formaldehyde, amines, phenols, bisphenol A (BPA), explosives, chemical warfare agents, and environmental pollutants. The sensitivity, selectivity and strategies for excluding interferents are also discussed for graphene-based gas and chemical sensors. The challenges for developing future generation of flexible and stretchable sensors for wearable technology that would be usable for the Internet of Things (IoT) are also highlighted.

Chipless Radio Frequency Identification (RFID) has been used in a variety of remote sensing applications and is currently a hot research topic. To date, there have been a large number of chipless RFID tags developed in both academia and in industry that boast a large variation in design characteristics. This review paper sets out to discuss the various design aspects needed in a chipless RFID sensor. Such aspects include: (1) Addressing strategies to allow for unique identification of the tag, (2) Sensing mechanisms used to allow for impedance-based response signal modulation and (3) Sensing materials to introduce the desired impedance change when under the influence of the target stimulus. From the tabular comparison of the various sensing and addressing techniques, it is concluded that although many sensors provide adequate performance characteristics, more work is needed to ensure that this technology is capable/robust enough to operate in many of the applications it has been earmarked for.

“…Nickel ferrite is of interest for research gas sensing because of their special properties at the nanometer scale such as quantum effects, surface effects, easy doping other metals, etc. [9][10][11][12][13][14][15][16]. The sensitivities of the electrical resistivity to acetone, ethanol, methane (CH4), and liquefied petroleum gas (LPG) of nickel ferrite doped with small ________ amounts of calcium, cobalt, and manganese were investigated [17].…”

In this paper, the synthesized and testing of H2 gas sensors using nickel zinc ferrite NiFe2O4 and Ni0.5Zn0.5Fe2O4 nanoparticles was shown here. The nickel zinc ferrite nanoparticles were synthesized by chemical co-precipitation combine annealed. Characterization of synthesized powders was made using X-ray diffraction (XRD) and Transmission electron microscopy (TEM) analysis. Nano powder resulting from milling was used to prepare gas sensing elements in pellet form. The gas-sensing properties were studied in presence of hydrogen as test gases. The gas response was found to be strongly influenced by the substitute concentration of Zn. A significant high sensitivity of ~ 90% was found for Zn = 0.5 in presence of 500 ppm H2 at an operating temperature of 250 °C.
