Bioinspired dry adhesives based on van der Waals forces have a wide range of impact in space operations, robot manipulation, and other fields. Previous studies confirmed the significant advantages mushroom-shaped structure uniformly distributing separation stress.

Here, we analyze mechanism contours contact-separation behavior adhesive structures by finite element analysis investigate enhancement properties structures. On this basis, propose one-step forming strategy inspired growth biological to obtain flow forming. The exhibit more excellent performance than those mutant adhesion test, which verifies correctness our proposed law contours' influence behavior, providing new idea for design adhesive-based systems.

Abstract Bioinspired microadhesives can generate strong adhesion at the interface through van der Waals forces, demonstrating promising potential applications across various fields. However, inherent conflicts between microstructural stability and compliance, as well easy detachment, significantly hinder development practical of microadhesives. In this work, wedged (WMs) dual‐gradient modulus are fabricated via magnetically assisted soft‐molding. The WMs exhibit a maximum shear performance 4.9 N cm −2 minimum normal 0.13 under same preload, achieving an excellent anisotropy ratio (AR) up to 37.7. generates greater gradient difference, with low facilitating maintain well‐conformal contact, while high enhances detachment capabilities, which simultaneously improve long‐term stability. Additionally, quadruped gripping mechanism is designed exhibited stable grasping on‐demand rapid release when integrated WMs, anisotropic performance. provide valuable solution for designing that both structural along detachment. These findings will greatly benefit reversible in on‐orbit servicing technology.
