Economic growth depends upon Micro, Small and Medium Enterprises (MSMEs) as they play a vital role in GDP and employment. Transportation is considered the lifeline of any country. In the last 10 years, ferrite-based sensors have been used primarily to detect harmful gases, pollutants from vehicle exhaust, and for environmental pollution monitoring. These soft ferrites have excellent electrical and magnetic properties that can be tuned to increase sensitivity and selectivity. The tuning of ferrite sensors depends upon synthesis technique, optimizing preparation conditions, sintering temperatures, operating temperatures, dopant concentration, etc. This paper is based on a deep study of the gas sensing mechanisms, parameters, and application of chemo-resistive metal oxide gas sensors. The key parameters for the ferrite gas sensors are phase formation, crystallite size, grain size, surface area, selectivity, dopants, sensitivity, gas concentration, operating temperature, response/recovery time. This review paper also includes the study of different researchers to find the impact of high concentration of gases like hydrogen, carbon monoxide, carbon dioxide , oxygen (O2), ethylene glycol 〖〖(CH〗_2 OH)〗_(2 ), methane (CH4), ammonia (NH3) liquid petroleum gas (LPG), acetylene (C2H2), and nitrogen oxides (NOx) in the environment and the metal oxide materials selected sensor applications.

“…The availability of printer with sophisticated coordinates tables for both the head and the chuck allowed to precisely print multiple layers and then to extend the range of applications of this technique. Over the last 10 years, the use of inkjet printing moved from the printed paper to the production of bio-scaffold [4][5][6][7], MEMS, sensors [4,8,9], printed circuit board [10][11][12], and flexible electronic devices [11,[13][14][15][16][17][18][19][20][21][22][23][24]. In this last field of aforementioned applications, one of the most used substrates is poly (4, 4 ′ -oxydiphenylene-pyromellitimide), commercially called Kapton [11,13,[17][18][19][20][21][22]25].…”

InkJet printing is a technique that in the last decades has attracted the attention of the scientific community because it allows producing customized patterns with a variety of inks and substrates, making it suitablemethod for the production of flexible circuits. However, the optimization of this technique is still problematic due to a large number of process variables. Among them the modification of the waveform parameters of the piezoelectric actuator that allows the ejections of the ink can be effective in tuning the printing quality. This work reports a study by a statistical method, namely Design of Experiments (DOE), to optimize the inkjet printing parameters for a nanoparticle-based silver (Ag) ink. This method showed the interplay of the waveform parameters into the definition of optimal drop reproducibility and the achievement of the optimal resolution. In particular, it is shown that mixed terms of the model have a statistical significance and therefore the proposed multifactorial approach provides a benefit in the optimization with respect to the more commonly used one-factor-at-a-time models (OFAT). For the first time, empirical equations have been reported within the corresponding 95% confidence intervals. These equations can be used as a tool to directly tune the properties of the printed dot by modifying the waveform parameters. As case study, we proposed the combinations of a commercial Ag nanoparticles ink with Kapton, a commonly used substrate for flexible electronics.

“…Also, more complex iron compounds have been studied as LPG sensors. So, Goutham et al 13 showed that Mg(x)Fe(1−x) 2 O 4 (x = 0.5) exhibited the highest sensitivity at 90 °C for 500 ppm LPG at 1 V applied compared to commercially available gas sensors. Bhaduri et al 14 revealed that Ni 0.4 Zn 0.6 Fe 2 O 4 (NZF) can be a highly sensitive LPG sensor that can effectively detect LPG below the lower explosive limit (LEL).…”

Modified Fe₃O₄ Magnetite Core@Shell Type Nanomaterials for Highly-Responsive LPG Sensing: A Comparative Analysis

et al. 2023

The present work focuses on synthesis of Fe3O4 magnetite core@shell type nanoparticles modified with three types of ligands: Magnetite with activated carbon (MAC), Magnetite with silica (tetraethoxysilane, TEOS, and 3-aminopropyltriethoxysilane, APTES) (MTA), and Magnetite with silica, APTES and humic acids (MTAH). The MTAH sample shows greater porosity in comparison to MTA, and MAC sample. The band gap of MTAH is 4.08 eV, which is higher than MTA (2.92 eV), and MAC (2.80 eV). Rietveld quantitative phase analysis of all derivatives was performed and compared for all three samples. The LPG sensing at room temperature shows the highest sensor response of 9.42, in comparison to 3.87 sensor response for MAC, and 4.60 for MTA. This approximately double sensor response increment is justified with the help of band gap, porosity, and size of all three the samples. The MTAH sample shows the lowest response-recovery time of 9.33 and 10.78 sec, respectively, in comparison to MAC and MTA samples.
