Nano- and micro-electromechanical systems (N/MEMSs) are traditionally based on electrostatic or piezoelectric coupling, which couples electrical mechanical energy through acoustic resonator structures. Most recently, N/MEMS devices magnetoelectrics gaining much attention. Unlike that rely an AC electric field voltage excitation, magnetoelecric the electromechanical resonance of a magnetostricti...

Pressure-induced activation of vascular smooth muscle may involve electromechanical as well as nonelectromechanical coupling mechanisms. We compared calcium-tone relations of cannulated rat mesenteric small arteries during pressure-induced activation, depolarization (16 to 46 mmol/L K+), and alpha1-adrenergic stimulation (1 micromol/L phenylephrine). The intracellular calcium concentration was ...

Cardiac tissue is a syncytium of coupled cells with pronounced intrinsic discrete nature. Previous models of cardiac electromechanics often ignore such discrete properties and treat cardiac tissue as a continuous medium, which has fundamental limitations. In the present study, we introduce a 2D electromechanical model for human atrial tissue based on the discrete element method (DEM). In the mo...

Fabrication of high quality nano-electromechanical systems (NEMS) is nowadays extremely efficient. These NEMS will be used as sensors and actuators in integrated systems. Their use, however, raises questions about their interface (actuation, detection, read out) with external detection and control systems. Their operation implies many fundamental questions related to single particle effects suc...
