Piezoelectric micromachined ultrasonic transducers comprising a 10 mu m thick Si device layer and a 14 pro thick piezoelectric PZT layer were investigated. The PZT films were deposited by a sol-gel technique. The transverse piezoelectric coefficient was me ...
This paper presents the modeling and design of one-dimensional metamaterial phase shifters (MPSs) in monolithic-microwave integrated-circuit technology based on the composite right/left-handed transmission-line approach. From a theoretical point-of-view, w ...
We present an integrated composite right/left handed transmission line (CRLH-TL) phase shifter analogically controlled by means of a MEMS series capacitor. The device is based on coplanar waveguide (CPW) technology and operates at a central frequency of 18 ...
A method to extract a lumped-parameter equivalent circuit for a free-free flexural MEMS resonator, based on the Euler-Bernoulli beam equation and exploiting a modal analysis approach, is presented. The dynamic behaviour predicted by the equivalent circuit ...
A design tool able to predict the residual stress state and dimensional stability of large complex shaped composite parts has been developed. It is based on a finite element model, using a three-dimensional anisotropic thermo-viscoelastic formulation. Asym ...
This work presents the preliminary results on application of mineral sacrificial layer that is prepared to structure LTCC (low temperature co-fired ceramic). The proposed method suggests utilization of a sacrificial paste, which remains "permanent" during ...
The research discussed in this article is motivated by the search for an optimal classification of the different types of atrial fibrillation (AF) on the basis of recorded atrial signals. This would facilitate the selection of an optimal therapy. This arti ...
In this paper the creation of "virtual prototypes" of complex micro-electro-mechanical transducers is presented. Creating these behavioural models can be partially automatised using a reduced-order modelling (ROM) method. It uses modal decomposition to rep ...
The register file is one of the hottest devices in processor- based systems. Leakage reduction techniques and DTM mechanisms re- quire a thermal characterization of the hardware. This paper presents a thermal model to analyze the temperature evolution in t ...
In this chapter the creation of "virtual prototypes" of complex micro-electro-mechanical transducers is presented. Creating these behavioural models can be partially automatised using a reduced-order modelling (ROM) method. It uses modal decomposition to r ...
