Modeling and Simulation of Dual Application Capacitive MEMS Sensor

A. Ravi[1], R. Krishna[1], J. Christen[1]
[1]Arizona State University, Tempe, AZ, USA

Capacitive MEMS sensors offer high spatial resolution, sensitivity and good frequency response. In this paper, we present a circular membrane capacitive MEMS device that finds use both as capacitive micromachined ultrasonic transducer (CMUT) and pressure sensor. The MEMS device is first ...

[3] Bern University of Applied Sciences Engineering and Information Technology, Bern, Switzerland

Introduction: This study describes a thin and low-cost capacitive pressure sensor in touch mode (TM) for monitoring fluid pressure from 0 to 40kPa in fluidic chambers with Luer fittings for medical applications. TM provides good linearity, large measuring range and large overload ... En savoir plus

Nanowire Based Flexible Piezoelectric Sensor for Structural Health Monitoring Applications

A. El Kacimi [1], E. Pauliac-Vaujour [1], J. Eymery [2]
[1] University Grenoble Alpes, CEA, LETI, MINATEC Campus, Grenoble, France
[2] University Grenoble Alpes, CEA, Grenoble, France

We report on the modeling of flexible piezoelectric capacitive sensor based on GaN wires grown by Metal Organic Vapor Phase Epitaxy. Single crystal cone-shaped wires with hexagonal cross section are embedded within dielectric layers (parylene) in between two metal electrodes to achieve a ... En savoir plus

Simulation of MEMS Based Pressure Sensor for Diagnosing Sleep Disorders

J. Vijitha[1], S. S. Priya[1], K. C. Devi[1]
[1]PSG College of Technology, Coimbatore, Tamil Nadu, India

Sleep apnea is a type of sleep disorder characterized by pauses in breathing or instances of shallow or infrequent breathing during sleep. There is a need to diagnose sleep apnea since it leads to fluctuations in the oxygen level that in turn affect the heart rate and blood pressure. In ... En savoir plus

Simulation of ZnO Enhanced SAW Gas Sensor

H. du Plessis[1], W. Perold[1]
[1]University of Stellenbosch, Stellenbosch, South Africa

Surface acoustic wave (SAW) devices are widely used for their sensing capabilities and gas sensing is only one of many uses. There is an ever increasing need to make them as effective as possible by adding nanomaterials to the device. In this study a two-port delay-line structure with ... En savoir plus

Improving the Design Process of a MEMS-IR-Emitter

Toni Schildhauer¹, Andreas T. Winzer¹, Julia Baldauf¹
¹CiS Forschungsinstitut für Mikrosensorik GmbH, Erfurt, Germany

In the rapid development cycle of sensor systems, minimizing time-to-market is crucial. However, designing a new MEMS-chip (Micro-Electro-Mechanical Systems) presents significant challenges due to the extensive time required for manufacturing and characterization. This delay affects the ... En savoir plus

Design of a Pressure Sensor to Monitor Teeth Grinding

I.M. Abdel-Motaleb[1], K. Ravanasa[1], K.J. Soderholm[2]
[1]Department of Electrical Engineering, Northern Illinois University, DeKalb, IL, USA
[2]Department of Restorative Dental Sciences, College of Dentistry, University of Florida, Gainesville, FL USA

Studying teeth grinding behavior and other oral conditions requires the ability to accurately measure the pressure on the teeth. Placing a sensor in the mouth requires small size devices with powering and measurement techniques that do not hinder the normal life of the patient. To meet ... En savoir plus

Air Convection on a Micro Hotplate Gas Sensor

S. Gidon[1], M. Brun[1], S. Nicoletti[1], P. Barritault[1]
[1]Commissariat Energie Atomique, LETI, Minatec Campus, Grenoble, France

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared ... En savoir plus

Optimization Of The Collection Of Sprays By An Enhanced Electronic Sensor

J. Berges[1], B. Barelaud[1], I. Niort[2], and J.L. Decossas[2]
[1]XLIM, Limoges, France
[2]Université de Limoges, France

We propose the study of an electronic sensor allowing the collection of sprays in free space. The detector consists of three elements: a photodiode situated in the center of the structure to which is applied a bias voltage, an aluminum ring which referenced to a voltage higher than that ...
