Modeling and Simulation of Piezoresistive Pressure Sensor for 2bar Application

M. Ramezani [1], M. El Barkouky [1],
[1] Melexis, Tessenderlo, Belgium

In this paper, we focused on modeling of the piezoresistive pressure sensors. The Structural Mechanics Module of COMSOL Multiphysics® software is used to model the sensor and make a comparative study of the MEMS pressure sensor with different shape and size of membrane. The impact of ... Read More

PIR Sensor Modeling and Simulation Using COMSOL Multiphysics® and its Ray Optics Module

M. Maaspuro [1],
[1] School of Electrical Engineering, Aalto University, Finland

PIR (Passive Infrared) sensor is the most widely used motion sensor for occupancy detection in building automation applications. Normally, only the binary information indicating presence or absence is used. However, an advanced analysis of the PIR sensor analog signal can results in more ... Read More

¹Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu

Liquid Metal Fast Breeder Reactor (LMFBR) employs molten sodium as coolant due to its suitable neutronic and thermal properties. Measurement of coolant flow rate is a very important factor both from operational and safety aspects of a fast reactor. Good electrical conductivity of liquid ... Read More

MEMS Based Sensor for Blood Group Investigation

M. Kaushik [1], S. Katti [1], V. Saradesai [1], P. Naragund [1], P. Vidhyashree [1], A. K. V. Nandi [1]
[1] B.V. Bhoomaraddi College of Engineering and Technology, Hubli, India

This article describes the design of MEMS based cantilever structure intended for determination of blood group and it is compared with manual method. Cantilever structure design has a sensing layer and when a blood sample comes in contact with this, results in coagulation. The surface ... Read More

Design and Simulation of Underwater Acoustic MEMS sensor

S. Prabhu [1], Nagbhushan [1],
[1] Nitte Meenakshi Institute of Technology, Bengaluru, Karnataka, India

Silicon based MEMS have wide applications in under water sensors. This work aims one such applications, hydrophone. Hydrophone detects the pressure variations of acoustic signals and noise in the water and produces an output voltage proportional to the pressure. Here the attempt is made ... Read More

Design and Implementation of Multichannel Piezoelectric Acoustic Sensor

R. S. Hallikar [1], S. Munshi [1], M. U. Kumari[1], K. Padmaraju[2],
[1] R. V. College of Engineering, Bengaluru, Karnataka, India
[2] JNTU Kakinada, Kakinada, Andhra Pradesh, India

This paper concentrates on developing a self-contained cochlea whose performance is at par with natural hearing. The Artificial Basilar Membrane (ABM) design is done in such a manner so as to get a performance similar to the natural hearing. Finite element analysis was done with the help ... Read More

Use of COMSOL® AC/DC Module to Model a EM Sensor Deployed to Monitor Steel Transformation

J. Shen [1], W. Jacobs [1], L. Zhou [1], P. Hunt [2], C. Davis [1],
[1] Advanced Steel Research Centre, WMG, University of Warwick, Coventry, UK
[2] Primetals Technology Limited, Christchurch, UK

Real-time microstructure monitoring is important during the cooling process for hot-rolled strip steel production, as the microstructure formed determines the mechanical properties required by customers. The materials magnetic and electric properties, relative permeability and ... Read More

3D Simulation of an Acceleration Sensor with Self-sufficient Energy Supply

L. Weber [1], L. Fromme [1], D. Zielke [2],
[1] University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany
[2] University of Applied Sciences Bielefeld, Institute BIFAM, Bielefeld, Germany

Piezo buzzers, made of piezoelectric material glued on a brass plate, are usually used as signaler, but the buzzer can also be used to convert mechanical into electrical energy. If acceleration influences the buzzer, the structure is bent by its mass and a voltage can be measured between ... Read More

A FEM Study of Displacement Sensor Based on Magnetostrictive/Piezoelectric Composite Material

Qingwei Liu [1], Hangjie Mo [1]
[1] Shanghai Jiao Tong University, Shanghai, China

This paper studies the application of laminate magnetoelectric (ME) material in displacement sensor. We studied the L-L block composite thanks to designed structure by coupling displacement signal with the displacement potential of ME composite. A nonlinear approximation is adapted to ... Read More

Design and Analysis of CO2 Sensor using COMSOL Multiphysics® Software

S. B. Umbarkar[1], G. Y. Rajput[1], R. Vasappanavara[1],
[1] Department of Electronics Engineering, RAIT, Navi Mumbai, Maharashtra, India.

In this paper, a carbon dioxide sensor is introduced. At present many CO2 sensors are available, but they all required power in the order of few watts, therefore they are not suitable for long term unattended operation. This paper gives the brief description of CO2 sensor modeling using ... Read More
