Design of Novel High Sensitive MEMS Capacitive Fingerprint Sensor

In this paper a new design of MEMS capacitive fingerprint sensors is presented. The capacitive sensor is made of two parallel plates with air gap. In these sensors, the capacitance changes is very important factor. It is caused by deformation of the upper electrode of sensor. In this study with making slots in upper electrode, using T-shaped protrusion on diaphragm in order to concentrate the f...

Sensor placement for leak monitoring

The goal of this chapter is to review recent developments on sensor placement for fault diagnosis in drinking water networks. Solving a sensor placement problem for fault diagnosis entails the evaluation of the diagnosis performance of a monitoring system for a certain sensor configuration. In model-based fault diagnosis the monitoring system is built upon a set of consistency indicators, which...

Optical pH Sensor Based on Quinizarin for Alkaline pH Regions

The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...

An ultra-sensitive optical MEMS sensor for partial discharge detection

A diaphragm-based interferometric fiber optical microelectromechanical system sensor with high sensitivity is designed and tested for on-line detection of the acoustic waves generated by partial discharges (PD) inside high-voltage power transformers. In principle, the sensor is made according to Fabry Perot interference, which is placed on a micro-machined rectangular silicon membrane as a pres...

Development of an Optical Gas Leak Sensor for Detecting Ethylene, Dimethyl Ether and Methane

In this paper, we present an approach to develop an optical gas leak sensor that can be used to measure ethylene, dimethyl ether, and methane. The sensor is designed based on the principles of IR absorption spectrum detection, and comprises two crossed elliptical surfaces with a folded reflection-type optical path. We first analyze the optical path and the use of this structure to design a mini...
