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.

Electromechanical coupling of waves in nerve fibres [PDF]

Biomechanics and Modeling in Mechanobiology, 2018
The propagation of an action potential (AP) in a nerve fibre is accompanied by mechanical and thermal effects. In this paper an attempt is made to build up a mathematical model which couples the AP with a possible pressure wave (PW) in the axoplasm and waves in the nerve fibre wall (longitudinal - LW and transverse - TW) made of a lipid bilayer ...
