Novel undercoupled radio-frequency (RF) resonant sensor for gaseous ethanol and interferents detection

“…Most importantly, since the sensor design is of high simplicity and free of ADC, it is highly suitable for flexible devices for wearable epidermal sensing applications and novel RFresonant sensor array integration demonstrated in [16] to achieve the smallest possible sensor size and highest possible fabrication simplicity for low-cost, mass-producible, and disposable applications. Such advantages are even more evident when comparing our novel sensor design to various ultra-sensitive capacitive sensor and sensor system designs, such as the CMOS zeptofarad capacitive sensor [17], the femtofarad microfluidic sensor [18], and the quartz crystal-based mechanical resonant sensor [19,20].…”

Synthesis and Characterizations of Novel Ca-Mg-Ti-Fe-Oxides Based Ceramic Nanocrystals and Flexible Film of Polydimethylsiloxane Composite with Improved Mechanical and Dielectric Properties for Sensors

“…The capacitive method, which uses open capacitor as a sensing element, has fast dynamic response and also good electronic circuit with fast response [8]. The new method developed by Matko et al reduces offset, temperature characteristic of main sensing element, temperature drift, and noise by switching method and it shows fast dynamic response [9]. Nevertheless, at high precision measurement, it is important to reduce any disturbing noise with good noise compensation [10].…”

Approaches for Selective Oxidation of Methane to Methanol

“…Next to Cu-CeO2, Ni-CeO2(111) is another suitable catalyst, as the ceria support can modify the electronic properties of nickel by increasing its oxidation state [117,118]. It has also been reported for water-assisted methane activation by Lustemberg et al [119], who co-fed methane, O2, and water to obtain stable catalyst activity, as shown in Figure 11.…”

“…Furthermore, ceria as support modifies the electronic properties of nickel by increasing its oxidation state. This modification can be typically important for applications such as electrical sensors, wherein no change in oxidation was reported with effect of temperature, aging, offset, and drift [117,118]. Strong metal-support interactions therefore play a crucial role in O-H and C-H bond dissociation.…”
