Compact Tubular Dielectric Elastomer Pump for Indoor Plants

Journal of Applied Polymer Science, EarlyView.
This study develops a mountable rolled dielectric elastomer pump (MRDEP) using silicone films and MWCNT‐based electrodes. The MRDEP is completely soft, silent in operation, and easily mounted on a piping system. We use dry stacking methods, fabricate a multilayer dielectric elastomer actuator (DEA), and a pre‐straining process in one direction before ...

Effects of nonlinear elasticity and electromechanical coupling on pressure coefficient of the light emission in group-III nitride quantum structures

Journal of Physics: Conference Series, 2008
We present theoretical studies of the effects of nonlinear elasticity and electromechanical coupling on the pressure coefficients of the light emission, dEE/dPext, in GaN/AlN and In0.2Ga0.8N/GaN superlattices with compressively strained quantum wells. We show that effect of the nonlinear elasticity, manifesting itself in pressure dependence of elastic ...

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.
