  • Structures with tunable stiffness
    Patent number: 12612731
    Abstract: A structure having a tunable modulus of bending (flexibility) composed of interlocking geometric particles arranged such that an external pressure/force causes them to jam together, increasing the stiffness of the overall structure. Methods for creating the external pressure can include the use of an envelope around the structure that can be evacuated of air.
    Type: Grant
