Dynamic Electromechanical Coupling of Piezoelectric Bending Actuators [PDF]
Micromachines, 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 ...

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.
