We have experimentally demonstrated a compact, integrated optical hydrogen sensor on a silicon-on-insulator platform. The sensor consists of silicon waveguide coated with a thin palladium film. The sensitivity and response time of the sensor was tested for volumetric hydrogen concentrations ranging from 0% to 4%. The proposed hydrogen sensor shows great potential as a building block for an opti...

This work presents a monolithically integrated temperature and humidity sensor based on microelectromechanical systems technology. The working the “bi-metallic” effect has advantages of wide range, high sensitivity, fast detection. polyimide parallel plate capacitive structure with microporous array upper electrode designed for sensitivity response. Numerical analysis COMSOL simulation showed t...

In this present research work, we presented a new Bottom Gate P-Type Organic Field Effect Transistor (OFET) humidity sensor and its applicability towards has been experimentally demonstrated. P-type organic semiconductor polyaniline (PANI) used in variety of applications, including logic circuit components, electromagnetic shielding, chemical sensing, anticorrosion. Humidity can be to monitor r...

Wireless sensor networks being a collection of numerous sensor nodes, each with sensing (temperature, humidity, sound level, light intensity, magnetism, etc.) and wireless communication capabilities, provide huge opportunities for monitoring and mathematical modeling of the time-evolution of the physical quantities under investigation. Starting from the measurements collected by the sensor node...
