Calorimetric Thermoelectric Gas Sensor for the Detection of Hydrogen, Methane and Mixed Gases
A novel miniaturized calorimeter-type sensor device with a dual-catalyst structure was fabricated by integrating different catalysts on the hot (Pd/θ-Al2O3) and cold (Pt/α-Al2O3) ends of the device. The device comprises a calorimeter with a thermoelectric gas sensor (calorimetric-TGS), combining catalytic combustion and thermoelectric technologies. Its response for a model fuel gas of hydrogen ...

متن کاملAn Efficient Piezoelectric Analysis for Quartz Crystal Nanobalance Gas Sensor
This paper presents an efficient scheme to design the most used biosensor Quartz crystal nanobalance (QCN). The main characteristic of QCN is very mass sensitivity. It means a little variation of deposited mass on the surface of QCN and it will cause the change of thickness-shear-mode resonant frequency. An electro-mechanical coupled-field 3D finite element method is applied to analyze the reso...
متن کاملCouple Stress Effect on Micro/Nanocantilever-based Capacitive Gas Sensor
Micro/nanocantilevers have been employed as sensors in many applications including chemical and biosensing. Due to their high sensitivity and potential for scalability, miniature sensing systems are in wide use and will likely become more prevalent in micro/nano-electromechanical systems (M-NEMSs). This paper is mainly focused on the use of sensing systems that employ micro/nano-size cantilever...
متن کاملMid-Infrared Trace Gas Sensor Technology Based on Intracavity Quartz-Enhanced Photoacoustic Spectroscopy
The application of compact inexpensive trace gas sensor technology to a mid-infrared nitric oxide (NO) detectoion using intracavity quartz-enhanced photoacoustic spectroscopy (I-QEPAS) is reported. A minimum detection limit of 4.8 ppbv within a 30 ms integration time was demonstrated by using a room-temperature, continuous-wave, distributed-feedback quantum cascade laser (QCL) emitting at 5.263...
