Stretchable electronic skin (e-skin) paves the way for applications that exceed scope of intrinsic rigid devices and hard-to-stretch sensors. The broad application range flexible e-skins benefits from device architectures can simultaneously provide mechanical flexibility superior sensitivity. Classic fractal design provides a simple architecture to achieve desired through structural improved we...

Our experiments demonstrate that alloying the cubic-phase $\mathrm{Yb}\mathrm{N}$ into wurtzite-phase $\mathrm{Al}\mathrm{N}$ results in clear mechanical softening and enhanced electromechanical coupling of $\mathrm{Al}\mathrm{N}$. First-principle calculations reproduce experimental well, predict a maximum 270% increase coefficient caused by (1) an piezoelectric response induced local strain $\...

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...
