In this Rapid Communication we show that the interplay between the deformation geometric-nonlinearity and distributions of external charges and dipoles lead to the renormalization of the membrane's native flexoelectric response. Our work provides a framework for a mesoscopic interpretation of flexoelectricity and if necessary, artificially "design" tailored flexoelectricity in membranes. Comparisons with experiments indicate reasonable quantitative agreement.
在这篇快速通讯中，我们表明，变形几何非线性与外部电荷和偶极子分布之间的相互作用导致了膜的固有挠曲电响应的重整化。我们的工作为挠曲电的介观解释提供了一个框架，并且在必要时可人为地“设计”膜中定制的挠曲电。与实验的比较表明了合理的定量一致性。
