“…The concept was developed either by conserving the initial standard structure (conducting sensitive gate deposited on the top of the transistor channel) or by changing it (e.g. sensitive gate separated by an air gap from the channel [2]) in the attempt to gain more flexibility. The latter version, suggestively named suspended gate field effect transistor (SG-FET), allows for the use of a larger number of materials and preparation methods for the sensitive gate, which is fabricated in a separate process.…”

“…The voltage is applied across the gate and drain terminal which will generate electric field which results in the conductivity of the transistor. When a polar compound and the gate metal interacts, it generates electric field and respond is recorded by the transistor [13,14]. The gate can be either thick (100-200 nm)or thin (6-20 nm).…”

Electronic Nose is one of the most advance device in the field of sensor technology. It is responsible for the automated detection and classification of gases, odors and vapors. This paper reviews the three components of Electronic Nose i.e. sample handling, detection system, data processing system. It outlines the range of sensors their principles, advantages and disadvantages. It describe the data processing through pattern recognition process. It also outlines the enormous benefits of Electronic Nose in the field of food control, clinical diagnosis, cosmetics, environmental factors, garbage control and detection of plant diseases.

Two different types of hydrogen response signals (DC and AC) of a proton pumping gate FET with triple layer gate structure (Pd / proton conducting polymer / Pt) were obtained. The proton pumping gate FET showed good selectivity against other gases (CH 4 , C 2 H 6 , NH 3 , and O 2 ). For practical use, the hydrogen response characteristics of the proton pumping gate FET were investigated in air (a gaseous mixture of oxygen and nitrogen). The proton pumping gate FET showed different hydrogen response characteristics in nitrogen as well as in air, despite the lack of oxygen interference independently. To clarify the response mechanism of the proton pumping gate FET, a hydrogen response measurement was performed, using a gas flow system and electrochemical impedance spectroscopy. Consequently, the difference in response between nitrogen and air was found to be due to the hydrogen dissociation reaction and the interference with the proton transfer caused by the adsorbed oxygen on the upper Pd gate electrode.
