To prevent further complications in diabetes, proper management of blood glucose levels is essential. By using ultrasonic transceivers (both transmit and receive) the glucose level of human blood can be determined. By using this ultrasonic technique miniaturized sensors for non-invasive ...

An acoustic energy harvesting mechanism at low frequency (~200 Hz) using lead zirconate titanate (PZT) piezoelectric cantilever plates placed inside a quarter-wavelength straight-tube resonator has been studied using COMSOL Multiphysics 4.3 and compared with experimental data. When the ... Mehr lesen
The Surface Acoustic Wave (SAW) linear motor was studied which is developed utilizing the friction principle for driving. The principle says that, when a slider is placed on the Rayleigh waves generated on a stator, the slider moves in reverse direction of the wave due to friction ... Mehr lesen
FEM (Finite Element Method) modelling software such as COMSOL Multiphysics® can be a powerful tool for modelling the behavior and response of piezoelectric materials and devices [1]. Devices based on piezoelectric crystals are particularly well suited, because the polarization magnitude ... Mehr lesen
The feasibility of phase-sensitive detection of angular-rates using bi-directional orbiting piezoresonators suspended by thick annular springs with thin-film aluminium nitride piezoactuators on top of them was investigated. The ring-shaped flexures are more suitable for supporting the ... Mehr lesen
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 ... Mehr lesen
The focus of this paper is to study the effect on resonance frequency and power enhancement techniques[1] of piezoelectric MEMS and modeling, design, and optimization of a piezoelectric generator based on a two-layer bending element(Figure 1) using COMSOL Multiphysics. An analytical ... Mehr lesen
Finite element analysis has been used to model the ultrasonic wave propagation both in a custom made transducer and in the tested polymer sample. The model consists of acoustic (passive elements) and electroacoustic (active elements) transmission lines. The simulation of the acoustic ... Mehr lesen
Turbomachines blades are forced by a load resulting from the interaction with the fluid. The consequent vibrations, and the associated fatigue phenomena, can give catastrophic failures and the reduction of the blades life. It could be increased if damping system are used. The ... Mehr lesen
In this paper, we present study on the mass loading effect of the interdigital transducer (IDT) on surface acoustic wave (SAW) velocity in SAW devices, using COMSOL Multiphysics. We have simulated a one port SAW resonator made on YZ lithium niobate substrate and investigated the ... Mehr lesen
