This paper presents numerical simulation of plate wave modes in thin stainless steel plates using a racetrack spiral coil electromagnetic acoustic transducer (EMAT), which works under the principle of acousto-elastic effect, called Lorentz force mechanism. EMATs are useful for non ... Mehr lesen
The objective of this research is to design a millimeter scale broadband energy harvester device through the use of a multi-cantilever beam approach with a non-linear geometry. In this research, we use COMSOL Multiphysics® software to design, simulate and analyze the voltage and power ... Mehr lesen
This paper presents an ongoing effort, motivated by developing self-contained sensors for structural health monitoring of inflatable structures, to model the process of extracting useable electrical power from the mechanical vibrations of thin, prestressed membrane structures. Energy ... Mehr lesen
The onshore wind turbine industry must overcome many technical, commercial, and environmental difficulties. A significant element for planning consent is operational noise. Acoustic limits are strictly enforced and can lead to near-neighbour complaints as well as contractual disputes. ... Mehr lesen
Optical tweezers work on the idea of non-contact Optical Pressure felt by transparent particles, when shined by coherent light source such as lasers. On the other hand when light falls on the metal it excites the electron inside it and make them free. When these free electron cloud ... Mehr lesen
AlGaN/GaN heterostructures are unique because the 2DEG at the interface is created by the difference in polarization properties of the AlGaN and the GaN layers; not due to intentional doping. In this work, a 3D model of an electrostatically actuated micro cantilever has been developed ... Mehr lesen
Vibrating mechanical tank components, such as quartz crystals and surface acoustic wave (SAW) resonators with Q’s in the range of 10e3–10e6, are widely used to implement high-Q oscillators and band pass filters in the radio frequency (RF) and intermediate frequency (IF) stages of ... Mehr lesen
Microelectromechanical systems (MEMS) are becoming more prevalent in today’s space technologies. The Visible Nulling Coronagraph (VNC) instrument, being developed at the NASA Goddard Space Flight Center, uses a MEMS Mirror to correct wavefront errors. This MEMS, the Multiple Mirror ... 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 shear mode of film bulk acoustic resonators (FBARs) is preferred to the longitudinal mode owing to its lower acoustic losses in a liquid. However in addition to mass loading, the resonance is also affected by temperature and liquid viscosity. These two parameters can either be sensed ... Mehr lesen
