Zinc oxide is an interesting material for bio and chemical sensors. It is a semiconducting metal oxide with potential as an integrated multisensing sensor platform, which simultaneously detects parameters like change in field effect, mass and surface resistivity. In this investigation we have used resistive sensor measurements with respect to oxygen sensitivity in order to characterize sensing ...

A high-sensitive sensor for NOx detection based on selective electrochemical reduction of NO2 is proposed. Electrochemical cell consisting of three metallic electrodes and YSZ electrolyte operates under electric polarization and allows selective NO2 detection in exhaust gases at 400-550°C. Electrical polarization applied between working and counter electrodes accelerates partial electrochemical...

A comparison was firstly done of the oxygen flux through the Bausch and Lomb Plano T lens, the Bausch & Lomb U3 lens, and the Duragel 75 lens with a sensor on the normal eye. The results showed that the Bausch and Lomb Plano T lens was the best for use with the sensor probe. The sensor was then used to obtain a comparison with the normal oxygen flux through a therapeutic lens on keratoplastic e...

In spite of the substantial amount of work done in optical sensor research, it is difficult to find a biochemical receptor/optical transducer scheme, which can be used for a device permitting the continuous monitoring of a chemical compound in clinical or environmental samples. Perhaps one of the most interesting alternatives is based on using biochemical receptors that, in the appropriate conc...

Adequate coverage is one of the main problems for distributed wireless sensor networks and The effectiveness of that highly depends on the sensor deployment scheme. Given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. In this paper, we apply fuzzy logic system to...

Reactive oxygen species (ROS) play a key role in a variety of biotic and abiotic stress conditions, therefore their direct measurement in vivo is of special importance. In this study, we describe two dansyl-based ROS sensors, the singlet oxygen specific DanePy; HO1889NH, which is reactive to both singlet oxygen and superoxide radicals and a rhodaminebased singlet oxygen sensor, HO-2941. In orde...

Various sensing materials have been demonstrated to increase the precision of technology. Nevertheless, this complicates fabrication process for integration obtain devices that can simultaneously accommodate various gas detectors, like electronic nose. The study here focuses on exploring response different functionalization specific provide an alternative way achieve selective multiple gases. T...
