A medical ventilator is an imperative device used to save life by delivering an assortment of air and oxygen into and out of the patients’ lungs to administer breathing or to assist obligatory breathing. The commercially available diaphragm based pressure sensors made up of silicon ... Read More
This paper presents the design and simulation of micromixer for Lab-On-Chip (LOC) applications. There are two types of micromixers: one is an active micromixer and another one is a passive micromixer. This paper investigates microfluidic flow characterization and mixing rate of two ... Read More
Various research activities are happening around the world on harvesting energy from green energy sources to satisfy the power requirements. Being an abundant form of green energy acoustic energy harvesting has been gaining importance despite the low power density of its sources. In ... Read More
This paper presents a unique design of MEMS based 4-bit shift register that perform shifting operation same as logic devices that are composed of solid-state transistors. The MEMS shift register design inherits all the advantages from MEMS switches and thus is expected to have more ... Read More
Micro cantilevers are the basic MEMS structures, which can be used both as sensors and actuators. The . The objective of this work is to study concept of pull-in voltage and how to reduce the same. Voltage is applied to upper cantilever beam and lower contact electrode is made as ground. ... Read More
In a solid core PCF, structural parameters and the number of rings in the cladding region decide confinement losses, dispersion coefficients as well as bending losses. This paper evaluates some of commercially available solid core photonic crystal fibers. The dispersion coefficients and ... Read More
In this work, a bimetallic strip based thermal sensor was designed using MEMS module of COMSOL Multiphysics® software to monitor the temperature rise in insulating oil which was used as coolant in transformers. The bimetallic strip was designed with different shapes such as cylindrical, ... Read More
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 ... Read More
Effective suspension and settling are critical for controlling biomass retention in a biogas digester. This paper developed a Computational Fluid Dynamics (CFD) model to simulate the hydrodynamic characteristics of multiphase flow in biogas digester. This is carried out by using COMSOL ... Read More
