Gecko-inspired stiffness control
Main content start
Structures typically have fixed mechanical properties post-fabrication. To enable structures to optimize their performance to a changing environment, we study structures with dynamically re-programmable stiffness throughout its operation. Gecko-inspired dry adhesives are used to reversibly bond layers in laminated hinges via van der Waals forces. This achieves bending stiffness control since the layers bend as a single structure when bonded and as individual thin layers when debonded. Electrostatic actuation is used for active control of stiffness.
