Dynamic Electromechanical Coupling of Piezoelectric Bending Actuators [PDF]

open access: yesMicromachines, 2016
Electromechanical coupling defines the ratio of electrical and mechanical energy exchanged during a flexure cycle of a piezoelectric actuator. This paper presents an analysis of the dynamic electromechanical coupling factor (dynamic EMCF) for cantilever based piezoelectric actuators and provides for the first time explicit expressions for calculation ...

A Fully Coupled Model for Electromechanics of the Heart [PDF]

open access: yesComputational and Mathematical Methods in Medicine, 2012
We present a fully coupled electromechanical model of the heart. The model integrates cardiac electrophysiology and cardiac mechanics through excitation-induced contraction and deformation-induced current. Numerical schemes based on finite element were implemented in a supercomputer.
