Rapidly Tunable and Highly Reversible Bio-Inspired Dry Adhesion for Transfer Printing in Air and Vacuum

Abstract

Tunable and reversible dry adhesion has attracted much attention in academia and industry due to its wide applications ranging from releasable joints to stamps for transfer printing. Here a simple yet robust magnetically actuated, aphid-inspired design of an elastomeric surface that provides rapidly tunable and highly reversible adhesion strength is reported. The magnetically actuated adhesive features open reservoirs filled with magnetic particles and encapsulated by a thin surface membrane, which can be deformed in a controlled manner via the magnetic field, thus to tune the adhesion. The combination of the rate dependent effect and magnetic actuation of the thin surface membrane offers continuously tunable adhesion with great switchability and quick response. Experimental and theoretical studies reveal the underlying physics and provide design guidelines to optimize geometries for broad control of adhesion. Demonstrations of this concept in stamps for transfer printing of silicon wafers in air and in vacuum with the selective and programmable mode illustrate the capabilities for deterministic assembly and the potential in the semiconductor industry.
