Electromechanics in vertically coupled nanomembranes [PDF]
Applied Physics Letters, 2019 We investigate the electromechanical actuation of a pair of suspended silicon nitride membranes forming a monolithic optomechanical array. By controlling the membrane resonators' tensile stress via a piezoelectrically controlled compressive force applied

Electromechanical coupling in polaronic ceria
JPhys EnergyOxygen-defective metal oxides like cerium oxides exhibit giant electrostriction and field-induced piezoelectricity due to a dynamic electrosteric interplay between oxygen defects, ${\text{V}}_{\text{O}}^{ \cdot \cdot }$ , and the fluorite lattice.

Electromechanical coupling across the gastroduodenal junction. [PDF]
Acta Physiol (Oxf)Abstract The gastroduodenal junction is uniquely capable of regulating digestive functions in the gastrointestinal system. The pyloric sphincter, which demarcates the stomach from the small intestine, acts as a mechanical and electrical barrier, isolating each organ, thus enabling independent behaviors that are critical for proper ...

Inactivation of the Kv2.1 channel through electromechanical coupling. [PDF]
Nature, 2023 AbstractThe Kv2.1 voltage-activated potassium (Kv) channel is a prominent delayed-rectifier Kv channel in the mammalian central nervous system, where its mechanisms of activation and inactivation are critical for regulating intrinsic neuronal excitability1,2.

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

A Preliminary Model of Gastrointestinal Electromechanical Coupling [PDF]
IEEE Transactions on Biomedical Engineering, 2011 Gastrointestinal (GI) motility is coordinated by several cooperating mechanisms, including electrical slow wave activity, the enteric nervous system (ENS), and other factors. Slow waves generated in interstitial cells of Cajal (ICC) depolarize smooth muscle cells (SMC), generating basic GI contractions. This unique electrical coupling presents an added

Strongly Coupled Nanotube Electromechanical Resonators [PDF]
Nano Letters, 2016 Coupling an electromechanical resonator with carbon-nanotube quantum dots is a significant method to control both the electronic charge and the spin quantum states. By exploiting a novel micro-transfer technique, we fabricate two strongly-coupled and electrically-tunable mechanical resonators on a single carbon nanotube for the first time.
