TOWARDS A NEW GAS SENSOR MICROSYSTEM USING ELECTROACTIVE POLYMERS THIN FILMS

doping gas concentration. The doping process is reversible, and the experimental results are interpreted in terms of adsorption and diffusion of the gas in the polymer, charge transfer, and transport of the injected carriers in the polymer chain. These experimental results and previous studies on other polymers and oxidizing gases demonstrate the potentiality of such materials to be used as sensitive part of gas sensors.

PREPARATION OF MoO3 THIN FILMS BY SPRAY PYROLYSIS AND ITS GAS SENSING PERFORMANCE

MoO3 thin films have been prepared by a simple spray pyrolysis technique at substrate temperature 250oC. The structure and morphology of thin films are characterized by X-ray powder diffraction (XRD), scanning electron microscopy and UV-vis spectroscopy. The gas sensing properties of MoO3 thin film is studied at gas concentration 400 ppm and working temperature of 100–400 oC. It was found that the sensitivity depended on the working temperatures and also H2S gas concentration. The results show

The Research of a New Iteration of the Circular Algorithm

foreign markets: differential algorithm, electrochemical analysis and infrared spectroscopy. Differential absorption algorithm can accurately calculate the concentration of most gases, but it will lose the broadband continuous absorption information in the characteristic absorption of gases, leading to some gas concentration measurement can not come out. For example, the absorption spectrum of nitrogen dioxide molecule in the ultraviolet band is mostly gradual continuous absorption, so differential

A HIGH RESOLUTION OF HUMAN BREATH GAS SENSOR AND THE ANALYSIS OF HYPERVENTILATION FOR RESCUE ROBOTICS IN DISASTER ZONES (IRIS2010)

This paper presents a new type of ultrasonic gas molecule concentration sensor for rescue robotics and the performance of developed sensor is investigated by applying as human breath gas measurement sensor. This devise can measure the change of the gas concentration with a sampling rate of 400 kHz. Ideal gas experiment results show that the proposed sensor could detect the difference between 5% CO2 and pure air over 50 dB S/N and could discriminate humidified air and pure air with 55 dB S/N

SYNTHESIS OF NANOSTRUCTURED ZrO2 FOR GAS SENSING APPLICATION

18 nm and 20 nm, respectively. Gas sensing properties of their thick films, which were fabricated by screen-printing to various gases (O2, NO2, C2H5OH, CO, CO2, NH3, LPG, H2S and H2) were tested in ambient air. The ZrO2 thick films showed a high response and selectivity to H2S gas. The effect of operating temperature, gas concentration on the sensing characteristics of these films towards H2S was discussed..

Microcontroller based Power Efficient Signal Conditioning Unit for Detection of a Single Gas using MEMS based Sensor

A low power MEMS based sensor along with the embedded power efficient signal conditioning unit (Microcontroller based), which can be used with any suitable sensor-network to detect and quantify variations in a particular gas concentration, has been reported in this paper. The power consumption of the MEMS gas sensor is ~ 70mW to 100mW depending upon its operating temperature (150-250°C) and that of entire signal conditioning unit (consisting of low noise amplifier, switch, microcontroller and
