Mechanics of living cells and tissues play a central role in many phenomena, from tissue shape formation (morphogenesis) to migration of cells within tissues. One prominent example is the epithelia – a sheet of cells tightly attached to one another. It provides a physical barrier to separate an organism’s interior from the external environment and serves as a structural support for inner ...

The diffusion of underactuated compliant hands is growing in the robotic community due to their robustness, adaptability, capability of exploiting environmental constraints while performing a task, availability and low cost. In particular the interaction with the environment and the simplification of the control is a central aspect in the design of the device. In this paper we exploit the ...

The detection back-action phenomenon has received little attention in physical, chemical, and biological sensors based on nanomechanical systems. We show that this effect is very significant in ultrathin bimetallic cantilevers, in which the laser beam that probes the picometer scale vibration largely modifies the resonant frequencies of the system. The light back-action effect is nonlinear, ...

The Large Hadron Collider at CERN has begun operations at 7 TeV center of mass energy. CERN plans to run at this energy until the end of 2012 with the goal of providing an integrated luminosity of a few fb?¹ to the CMS and ATLAS experiments. The LHC will then shut down for 1.5 to 2 years to make the revisions necessary to run at ~14 TeV. Operation resumes in 2014. In 2017/18, there will be ...

This paper presents the design and simulation of novel micrometer-scale capacitive temperature sensors, which could serve as a component for miniaturized wireless sensor nodes for the internet of things requiring structural flexibility and optical transparency. The proposed sensor design employs a conventional, planar interdigitated capacitor structure, explores the thermo-mechanical property ...

The objective of this work is to develop a MEMS based Variometer to measure the vertical speed and to sense the instantaneous rate of climb or descent in Aircrafts to meet the miniaturization requirements in avionics industry. The design consists of dielectric material in between two micro electrodes. The micro diaphragm is placed on one of the electrode. As the aircraft changes altitude, the ...

The production model in the COMSOL Multiphysics® software makes use of the most up-to-date PIE data, material property inputs, and modeling methodology. The fully coupled thermo-mechanical equations are solved over the entire domain, significantly increasing the degrees of freedom required for a solution, in addition to several other improvements in the computational methodology of the model. ...

Si-infiltrated SiC porous composites exist in different forms composed of cores of cellular ceramic and skin plates of ceramic matrix composites. Due to high thermal conductivity, low coefficient of thermal expansion, high elastic modulus and high strength, the final product can be a promising candidate for applications in temperatures up to 1500 K such heat exchangers, recuperators and solar ...

This paper will give a short overview of use of COMSOL Multiphysics for analyzing ancient Greek and Roman catapults with the main focus on the energy storing torsion springs. Catapults have been known and used in the Greek and Roman world from around 399 BC and a fully standardized design for powerful torsion catapults emerged around 270 BC, based on one basic factor, the diameter of the torsion ...
