Trumpet-shaped controllable adhesive structure for manipulation of millimeter-sized objects

Reversible adhesion has great potential in a broad range of applications such as robotic grasping, transfer printing, and precision assembling. Herein, we show a trumpet-shaped controllable adhesive structure capable of grasping and releasing millimeter-sized three-dimensional objects with an instability modulation strategy. Experimental results revealed that the strong grasping capacity via compressing derives from the dual contribution of...
