Investigation on electro-controlled electromechanical coupling characteristics [PDF]
, 1997 Based on the first and second equations of piezoelectricity, by introducing the electrostrictive effect generally existed in ferroelectrics, in this paper, an equation of electro-controlled electromechanical coupling characteristics has been worked out ...

Coupling of voltage sensors to the channel pore: a comparative view
Frontiers in Pharmacology, 2012 The activation of voltage-dependent ion channels is initiated by potential-induced conformational rearrangements in the voltage-sensor domains that propagates to the pore domain and finally opens the ion conduction pathway.

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry
Advanced Functional Materials, EarlyView.A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result

Advanced Functional Materials, EarlyView.Ultrasoft silicone elastomers often sacrifice surface functionality for mechanical compliance. In Mold Star, low‐molecular‐weight species form a dispersed phase that weakens the network and passivates the surface. Solvent extraction removes this phase, unexpectedly improving both extensibility and metallization performance, enabling conductive ...

Equivalent parameter model of 1-3 piezocomposite with a sandwich polymer
Results in Physics, 2018 A theoretical model was developed to investigate the performance of 1-3 piezoelectric composites with a sandwich polymer. Effective parameters, such as the electromechanical coupling factor, longitudinal velocity, and characteristic acoustic impedance of

Biomechanics of Cardiac Electromechanical Coupling and Mechanoelectric Feedback [PDF]
Journal of Biomechanical Engineering, 2014 Cardiac mechanical contraction is triggered by electrical activation via an intracellular calcium-dependent process known as excitation–contraction coupling. Dysregulation of cardiac myocyte intracellular calcium handling is a common feature of heart failure.

Advanced Healthcare Materials, EarlyView.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...
