Couple 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...

Gas Sensor Based on Large Hollow-Core Photonic Bandgap Fiber

One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...

Numerical Modeling of a Nanostructure Gas Sensor Based on Plasmonic Effect

In the present paper, a nanostructure plasmonic gas sensor based on ringresonator structure at the wavelength range of 0.6-0.9 μm is presented. The plasmonicmaterials/SiO2 with the advantage of high mobility and low loss is utilized as a substratefor structure to obtain some appropriate characteristics for the sensing Performanceparameters. To evaluate the proposed senso...
