An extremely simple structural design of a composite material composed of an elastomer sheet and hard beads embedded at the surface is proposed to realize a shape-tunable surface; it reversibly forms bumps/undulations in response to in-plane tensile strain applied to the surface. Tribological properties such as adhesion therefore become switchable.

嵌入珠粒的弹性体表面的可切换凸点，具有可变的附着力†

为了实现形状可调的表面，提出了一种非常简单的由弹性体片和嵌入表面的硬珠组成的复合材料的结构设计。它会响应施加到表面的面内拉伸应变而可逆地形成隆起/起伏。因此，摩擦特性（如附着力）变得可切换。
