Review on Electromechanical Coupling Properties of Biomaterials

ACS Applied Bio Materials, 2018
Electromechanical coupling properties of biological materials, especially cellulose from plant cell walls and proteins from animals, are of great interest for applications in biocompatible sensors and actuators and ecofriendly energy harvesters. On the basis of their anisotropic nanostructures, cellulose and fibrous proteins such as collagen, silk ...

Electromechanical coupling and the conducted vasomotor response

American Journal of Physiology-Heart and Circulatory Physiology, 1995
Conducted vasomotor responses are viewed as one mechanism that functionally integrates the microvasculature. It is hypothesized that the conducted vasomotor response is the result of an electrical current and its passive electrotonic spread along the length of a microvessel.

Chemico-electromechanical coupling in microporous media

Journal of Colloid and Interface Science, 2006
We determine the macroscopic transport properties of isotropic microporous media by volume-averaging the local Nernst-Planck and Navier-Stokes equations in nonisothermal conditions. In such media, the excess of charge that counterbalances the charge deficiency of the surface of the minerals is partitioned between the Gouy-Chapman layer and the Stern ...

On Electromechanical Coupling in Elastomers

Journal of Applied Mechanics, 2012
Permittivity of electroactive elastomers alters during deformation. The influence of the permittivity alterations on the electrostriction of elastomers is studied in the present work. Particularly, acrylic elastomer VHB 4910 is considered. A polarization–electric field constitutive theory is introduced accounting for the influence of mechanical ...

SYNCHRONIZATION OF TWO ELECTROMECHANICAL DEVICES WITH PARAMETRIC COUPLING

International Journal of Bifurcation and Chaos, 2008
The study of synchronization of two electromechanical devices with parametric coupling, in their regular and chaotic states was investigated. It was observed that an analytical study based on the Floquet theory makes it possible to determine the coefficients of coupling, ensuring a complete synchronization.

Electromechanical coupling in a biopolymer gel

Polymer, 1992
Experiments on electromechanical coupling in aqueous gels of the polysaccharide agarose are described. The gels are prepared as free self-supporting discs between 1 and 4.5 mm thick immersed in water and in contact with a stainless-steel electrode system on a solid substrate.

3D Cardiac Imaging of Electromechanical Coupling

1997
A novel method for three dimensional (3D) electromechanical mapping of the heart is presented. The new method is based on utilizing special magnetically locatable catheters connected to a mapping and navigation system. The 3D electromechanical map of the chamber is reconstructed by sampling the location of the catheter tip throughout the cardiac cycle ...

Electromechanical Coupling of PZT Nanofibers

Volume 13: Nano-Manufacturing Technology; and Micro and Nano Systems, Parts A and B, 2008
This paper presented the results of electromechanical characterization of PZT nanofibers through applied mechanical strain and forced vibration. PZT nanofibers were fabricated by electrospinning process. Titanium film with ZrO2 layer was used to collect the nanofibers and also used as the substrates of the test coupons for the bending tests. Mechanical
