  text: Advances in shape-morphing materials, such as hydrogels, shape-memory polymers
    and light-responsive polymers have enabled prescribing self-directed deformations
    of initially flat geometries. However, most proposed solutions evolve towards
    a target geometry without considering time-dependent actuation paths. To achieve
    more complex geometries and avoid self-collisions, it is critical to encode a
    spatial and temporal shape evolution within the initially flat shell. Recent realizations
    of time-dependent morphing are limited to the actuation of few, discrete hinges
    and cannot form doubly curved surfaces. Here, we demonstrate a method for encoding
    temporal shape evolution in architected shells that assume complex shapes and
    doubly curved geometries. The shells are non-periodic tessellations of pre-stressed
    contractile unit cells that soften in water at rates prescribed locally by mesostructure
    geometry. The ensuing midplane contraction is coupled to the formation of encoded
    curvatures. We propose an inverse design tool based on a data-driven model for
    unit cells’ temporal responses.
