## Description

- description: 'Mechanical metamaterials are artificial structures with structure-dependent
    properties. They often harness zero-energy deformation modes. We address this
    limitation using a flexible material, called light-responsive shape-memory polydimethylsiloxane
    (SM-PDMS), to introduce reprogrammability into flexible mechanical metamaterials.
    Assisted by the crystal-amorphous transition of the shape-memory (SM) polymer,
    we designed three different flexible metamaterials with distinctive deformation
    modes: auxetic SM-PDMS, chiral SM-PDMS, and buckling-induced SM-PDMS. Their deformation
    modes can be reprogrammed into inverse responses through local light stimulations:
    from expansion to shrinkage, clockwise twist to counterclockwise, and clockwise
    rotation to counterclockwise, respectively. Finally, we demonstrated the application
    of harnessing buckling-induced SM-PDMS to make a soft actuator with a reprogrammable
    preferred locomotion direction. Although we focus on reprogramming flexible metamaterials
    using the light-induced SM effect, our strategy can be easily extended to other
    structures and smart materials. Furthermore, our designed flexible metamaterials
    have the potential for different applications, such as soft robots, actuation,
    adaptive safety, and sports equipment.'
