Calcium doped lanthanum and yttrium manganite electrode materials with oxygen deficiency and low polarization resistance (<30Ω*cm at 600°C) were tested in new advanced electrochemical sensor for the oxygen measurements. Oxygen sensor with oxide electrodes was showing fast response INTERNATIONAL JOURNAL ON SMART SENSING AND INTELLIGENT SYSTEMS, VOL. 5, NO. 1, MARCH 2012

A simple simulation using SIMULINK is presented to model the thermal/control behaviour of a domestic gas boiler. The simulation was the first step in a research programme to investigate the efficacy of control using an oxygen sensor. A brief review of boiler control is used to outline current practice and research developments. Ratio control in several forms has been investigated. Performance i...

This paper describes the response characteristics of a Clark type oxygen sensor using microelectrodes under a variety of operating conditions. The silicon based microelectrodes were fabricated using a CMOS process with Pt surface using a lift-off process. The Clark type sensor was configured using a threeelectrode system. A set of four operating conditions with varying activation voltages, the ...

A miniature Nernstian-type oxygen sensor employing an ionically conducting stabilized zirconia solid electrolyte and an embedded internal reference electrode is developed and is tested in the temperature range 275– 425 °C. It is intended for in situ monitoring of oxygen content in deposition and growth environments. Advantages of this sensor are in situ generation of the Ni/NiO two phase intern...

Despite the great potential of fluorescence microscopy, its application to date has largely been in the study of biological specimens. It will be shown that conventional fluorescence microscopy provides an invaluable tool with which to study the photophysics of polymer-supported luminescence-based oxygen sensors. The design of the imaging system, the measurement methods, and the data analysis u...

A flexible, highly sensitive sensor of oxygen in non-aqueous solvents is described. It consists of CdSe/ZnS nanoparticles decorated with a considerable number of pyrene units, thus making the formation of the pyrene excimer possible. The emission of the pyrene excimer and that of the nanoparticle are suitably separated from each other and also from the excitation wavelength. This sensor can be ...

Low cost sensor technology has made real-time monitoring of oxygen production and consumption from plants practical and affordable in homes. We describe an automated sensor based monitoring system comprising an oxygen sensor, a light sensor, and an automated data logging program that together enable near real-time measurement of oxygen production from common house plants. The results from the u...

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...

Recent research has shown that control of the oxygen content in the catalyst has potential to further reduce the emissions from spark ignited engines. This gives rise to a cascade structure where an outer loop influences an inner loop. Different ways of augmenting the inner loop, a traditional PI-feedback controller based on feedback from the binary oxygen sensor, are studied. The SI-engine con...

Soft-lithography and plasma etching with reactive ions were used to fabricate a polymer microfluidic cell-culture bioreactor with integrated optical oxygen sensor. Platinum(II) octaethylporphyrin ketone (PtOEPK) suspended in a microporous polystyrene (PS) matrix was spin-coated to form sensor films of variable thickness from 1.1 μm to 400 nm on glass substrates. Sensor films were found to be sm...
