Coupling of photomechanical and electromechanical actuations in carbon nanotubes
Nanotechnology, 2013It is known that carbon nanotubes (CNTs) possess multifunctional characteristics, which are applicable for a wide variety of engineering applications. CNT is also recognized as a radiation sensitive material, for example for detecting infrared (IR) radiations. One of the direct implications of exposing CNTs to radiation is the photomechanical actuation

Symmetry in the Equations for Electromechanical Coupling
The Journal of the Acoustical Society of America, 1950The conventional forms of the electromechanical coupling equations exhibit symmetry for electrostatic coupling and antisymmetry for electromagnetic coupling, or vice versa. Both types of coupling can be represented in symmetrical form, however, if the transduction coefficient for electromagnetic coupling includes a space-operator k that embodies the ...

Electromechanical coupling in electrostatic kinetic energy harvesters
2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2016Almost all kinetic energy harvester (KEHs) are inherently nonlinear. In addition, most practical systems introduce supplementary nonlinearity to improve their performance. Qualitatively and quantitatively understanding the nonlinear behaviour in these devices can highlight important parameters with regard to optimisation and design.

Strong coupling in electromechanical computation
Journal of Magnetism and Magnetic Materials, 2000Abstract A method is presented to carry out simultaneously electromagnetic field and force computation, electrical circuit analysis and mechanical computation to simulate the dynamic operation of electromagnetic actuators. The equation system is solved by a predictor–corrector scheme containing a Powell error minimization algorithm which ensures that

Duality in the Electromechanical-Coupling Factor
The Journal of the Acoustical Society of America, 1963Two electromechanical-coupling factors are distinguished in order to account for the behavior of transducers at low frequencies, as well as in the vicinity of mechanical resonance. The existence of the two coupling factors requires that the equivalent circuit be reinterpreted but not revised.

[Systems of electromechanical coupling].
Ukrainskii biokhimicheskii zhurnal (1978), 1982The paper considers the participation of membrane structures of cardial, skeletal and smooth muscles in the electromechanical splings. Membrane control of the level of ionized calcium in myoplasm is analyzed in details. The evidence is presented on Ca-channels, Ca-pump, system of Na+, Ca2+-metabolism and Na+, K+-ATPase of the surface membrane and Ca ...

Introduction to Electromechanical Coupling
2010This paper is dedicated to the physical understanding of electrostatic forces with a one-dimensional reference problem. First a non-dimensional analysis prescribes the kind of assumptions to consider for the electric field model. An analytical study of electro-mechanical coupling is then performed to understand the type of non-linearity added by ...

Experimental and Computational Modeling of Cardiac Electromechanical Coupling
2001Perturbations in ventricular mechanical loading can be arrhythmogenic and have been associated with sudden cardiac death in patients suffering from congestive heart failure, dilated cardiomyopathy, or ventricular volume overload (1–3). Stretch-induced changes in action potential propagation or repolarization could provide a mechanism for mechanically ...

Scalable BDDC Algorithms for Cardiac Electromechanical Coupling
2017The spread of electrical excitation in the cardiac muscle and the subsequent contraction-relaxation process is quantitatively described by the cardiac electromechanical coupling model. The electrical model consists of the Bidomain system, which is a degenerate parabolic system of two nonlinear partial differential equations (PDEs) of reaction-diffusion
