Blind cave fish are capable of sensing flows and movements of nearby objects even in dark and murky water conditions with the help of arrays of pressure-gradient sensors present on their bodies called lateral-lines. To emulate this functionality of lateral-lines for autonomous underwater vehicles, an array of polymer MEMS pressure sensors have been developed that can transduce underwater ...

Smart fabrics enable the integration of electronics into fabric. They can serve as a suitable sensor providing around-the-clock assistance for the real-time monitoring of health parameters. Here, we aim to develop a free-standing piezoelectric cantilever sensor integrated into conventional fabric to improve its functionality. These smart sensors have the ability to convert physiological ...

A grand variety of microactuator technologies and demonstrators has been introduced during the last years. Of particular interest are the microactuators based on phase change materials and especially paraffin wax, which can volumetrically expand up to 15%, providing high force actuation. The object of this study is the numerical validation of a paraffin microactuator concept by coupling multiple ...

Adulteration of automobile fuels, especially petrol and diesel is a rampant malpractice in India. With the rising prices of fuel and the subsidy on kerosene, getting away with even 10-15% adulteration is immensely profitable.To check adulteration effectively, it is necessary to monitor the fuel quality at the distribution point itself. The equipment for this purpose should be handy and the ...

A wide variety of near-field optical phenomena such as apertureless near-field scanning microscopy (ANSM) at optical and terahertz (THz) regimes and surface enhanced Raman scattering relies on the electric field enhancement at the end of a sharp tip. Achieving and controlling this electric field enhancement is a key challenge for a wide range of applications such as surface modification, data ...

The microscopic size of MEMS devices accounts for strong coupling effects which arise between the different physical fields and forces. Micromirrors are essential parts of microswitches in fiber optic network telecommunication. They are usually 1 to 3 mm in size, fabricated from single crystalline silicon and mostly are electrostatically actuated. The objective is to design the micromirror to ...

A two-dimensional atrial tissue model has been constructed in COMSOL Multiphysics® software to study the propagation of action potential and electrograms. The model presents the atrial electrograms recorded with a mapping catheter. A 2D atrial tissue model is simulated using the Courtemanche et al. cell model equations. PDE in coefficient form was used in COMSOL Multiphysics® to reproduce the ...

This paper presents the modeling and simulation of electro-thermo-mechanical self-oscillators, an emerging type of M/NEMS-enabled timing devices in which sustaining electronic amplifiers are not required for their operation. Indeed, they realize amplification in the mechanical domain and feedback by crossing three physical domains: electrical, thermal and mechanical. In a previous work , we ...

There has been growing demand for high performance micro sensors capable of detecting nuclear radiations being released from various industries, Nuclear reactors. Radiations emitted from the radioactive materials are invisible and not directly detectable by human senses. Thus it is highly essential to work on design of bolometers with absorptive elements providing optimum sensitivity. The ...

In this research, we use the COMSOL Multiphysics® software to design and simulate a digital microfluidic droplet adapter for board-level biochip integration. Digital Microfluidic Biochip (DMFB) has gained tremendous research interest in recent years due to its importance in Lab-on-a-Chip and other bio-MEMS (bio-Microelectromechanical Systems) devices. However, different DMFB microarray from ...
