At present, a great deal of research effort has been directed to find eco-friendly and renewable sources of energy. With the rising costs of crude oil and petroleum, along with the derogatory effects that they pose to the environment, this sort of approach is of utmost importance. This has also led to the search for alternate methods of transforming the various forms of energy into electrical ...

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 pressure ...

For the last two centuries, the conventional Fourier heat conduction equation has been used for modeling a diffusive nature of macroscale heat conduction by considering the energy conservation and Fourier's linear approximation of heat flux. However, it cannot accurately predict heat transport when the length scale is comparable to or smaller than the mean free path of thermal energy carriers or ...

Study of Artificial Molecular Engines Action Through COMSOL Multiphysics® Program

Rotaxanes are a class of molecules recently developed in laboratory that have been heralded as possible molecular motors. The motor is constituted by a linear molecule (thread) and a ring-shaped molecule (macrocycle), which is free to move along the thread, switching between two, or more, energetically stable interaction points (stations). Molecular motors start their functioning far from ...

Design and Simulation of MEMS Based Gyroscope for Vestibular Prosthesis

The primary function of the vestibular system is to provide the brain with information about the body\'s motion and orientation. The absence of this information causes blurred vision and spatial disorientation, vertigo, dizziness, imbalance, nausea, vomiting, and other symptoms often characterize dysfunction of the vestibular system. Our aim is to design vestibular prosthesis using COMSOL ...

This paper discusses the simulation studies on a vibration based energy harvesting system to convert the undesirable mechanical vibration to useful green power. The design consists of a resonating proof mass and a spring system enclosed in housing and fixed on the source of vibration. A piezoelectric suspension acts as the transducer and generates a voltage that is used to charge the batteries of ...
