The MEMS microphone is also called microphone chip or silicon microphone. The pressure sensitive diaphragm is etched directly into a silicon chip by MEMS techniques and is usually accompanied with integrated preamplifier. Most MEMS microphones are variants of the condenser microphone ... Mehr lesen
This paper presents a novel design of single-bit RF MEMS phase shifter. The basic novelty introduced for phase shifter design in this case, is by scaling down of the lateral dimensions of the conventional RF MEMS shunt switch by 10 times. The Mechanical and Electromechanical analysis ... Mehr lesen
The simulation of the piezoelectric actuation of the micro-cantilever is presented. Lead Zirconate Titanate (PZT) was chosen for the device fabrication design, due to its thin film processing flexibility. Four layers compose the cantilever structures presented in this work: PZT ... Mehr lesen
The main objective of this study is to verify the compliance of an ongoing nuclear facilities stack design with the ISO 2889 requirements, during normal and off-normal conditions. In particular, with the numerical simulations, they have been identify well-mixed sample locations along the ... Mehr lesen
In this paper 3D electro-thermal FE Model using COMSOL Multiphysics® software of power vertical MOSFET used in the automotive industry is presented. This model is used to analyze the effects of bonding wire lift off defect and to study the influence of metallization thickness and ... Mehr lesen
This paper presents an analysis approach of multicondcutor quasi-TEM lines transmission interconnect in a single dielectric region and multimode waveguides using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in ... Mehr lesen
Development of very high speed integrated circuits is currently of great interest for today\'s technologies. This paper presents the quasi-TEM approach for the accurate parameters extraction of multiconductor transmission lines interconnect in single, two, and three-layered dielectric ... Mehr lesen
In our experiments with manipulating cells with DEP, we noted that some cells are constantly spining. By hypothesing that the cell spining is caused by the non-circular shape of the cell body and the off-centered location of its nucleus and that the rotation direction depends on the ... Mehr lesen
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 ... Mehr lesen
Additive manufacturing uses 3D printing to build physical parts from CAD-based designs. The technology includes fused deposition modeling (FDM) and selective laser sintering (SLS) methods. 3-D printing is of particular interest for smaller, one-of-a-kind, customizable products. A cube ... Mehr lesen
