When placing a loudspeaker in a cabinet, standing waves inside the cabinet affect the frequency response with ripples. This peaks and dips due to pressure cancellation inside the cabinet have an effect on the diaphragm and generating sound out from the vents. If it was in a condition of ... Mehr lesen
The quaternary mirror (M4) of the Extremely Large Telescope will be equipped with an Adaptive Optics Unit, in order to compensate the effects of the atmospheric turbulence. The highly accurate, closed loop actuation of the thin mirror is provided by 5316 contactless actuators. Their core ... Mehr lesen
Plasmonic gratings like bull's eye can localize E field due to excitation of surface plasmons and when integrated with Ge-on-Si photodetector they can help in fabrication of ultra small photodiodes with high sensitivity. We have numerically carried out a frequency analysis for the ... Mehr lesen
In this work, a MEMS low-g accelerometer with three sensitive directions is designed for health monitoring applications. The accelerometer may have different sensitivity in different axes. The proof-mass of the device is suspended by four serpentine springs, and the comb drive structure ... Mehr lesen
Functionally graded materials (FGM) are those that contain chemical, phase or structural gradients. Whilst the design of functionally graded structures is well researched in areas such as shape optimisation and topology optimization, their manufacture is still in development. One ... 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
This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric ... Mehr lesen
Pulse-echo FEM simulation is seldom found in literature for ultrasound imaging array probes, since the complete modeling of such device is extremely complicated. Nevertheless, the 2D FEM described in the present work was successful, thanks to the following design procedure (see figure): ... Mehr lesen
In this study, a detailed finite element model coupling the motion dynamics and electromagnetics of a diaphragm based MEMS vibration energy harvester is presented. The energy harvester converts low frequency vibrations to high frequency response by magnetic actuation of a diaphragm ... Mehr lesen
It is very difficult to measure the global properties of heterogeneous and anisotropic materials like composites and sandwich structures. When designing composite sandwich applications, the elastic properties are required to perform structural stiffness and strength calculations. ... Mehr lesen
