Various strategies to achieve superior converse flexoelectric response, qualitatively and quantitatively, in dielectric materials are presented. For the qualitative aspect, a novel approach for achieving converse flexoelectric effect independent of geometry or material composition of dielectric materials, by having modified electrical boundary conditions is presented. The theoretical investigation of the proposed methodology is presented and compared with the existing methods (functional grading and trapezoid-shaped sample). Later, the hybrid configurations of existing methods with the proposed strategy are analyzed and are found to enhance the actuation in some cases while decreasing in others, suggesting the possibility of a quantitatively superior effect. While the proposed method of varying electric field direction is established as an alternative to existing methods to induce electric field gradient, the FGM is found to exhibit up to 380% actuation of the closest non-hybrid strategy, i.e. trapezoid geometry.

提出了在介电材料中定性和定量地获得优异的逆向柔电响应的各种策略。对于质量方面，提出了一种新颖的方法，该方法通过修改电边界条件来获得与电介质材料的几何形状或材料组成无关的逆向柔电效应。提出了所提出方法的理论研究，并与现有方法（功能分级和梯形样品）进行了比较。随后，分析了现有方法与所提出策略的混合配置，发现在某些情况下增强了驱动，而在另一些情况下却减少了，这提示了量化效果更好的可能性。
