Abstract

A fiber-elastomer composite design with a vastly improved and directional actuation response is proposed for dielectric elastomer actuators. The all-elastomer composites are capable of achieving remarkably high actuation stresses, directional strains, electromechanical coupling efficiencies, and energy densities at relatively low electric fields. Their electromechanical metrics are among the highest reported for this class of electroactive materials.

摘要

针对介电弹性体致动器，提出了一种具有大大改善和定向致动响应的纤维-弹性体复合材料设计。全弹性体复合材料能够在相对较低的电场下实现显著高的致动应力、定向应变、机电耦合效率和能量密度。它们的机电指标在这一类电活性材料中是最高的之一。
