| Abstract Scope |
For the first time, the dynamic response of bioinspired gecko-like fibrillar adhesives is explored following impact of a stiff object at different velocities. The object was dropped in free fall and the subsequent gripping behavior exerted by the fibrillar microstructure was characterized by adhesion measurements and by monitoring with a high-speed camera. We varied parameters such as drop height, object mass, microstructure parameters and backing layer properties. A range of relative velocities was identified that maximizes the resulting adhesive strength for a given microstructure. The results suggest optimization strategies for microstructures under dynamic conditions and demonstrate the feasibility of using these adhesives for capturing moving objects, such as satellite debris in outer space. |
