Abstract

Low modulus materials that can shape-morph into different three-dimensional (3D) configurations in response to external stimuli have wide-ranging applications in flexible/stretchable electronics, surgical instruments, soft machines and soft robotics. This paper reports a shape-programmable system that exploits liquid metal microfluidic networks embedded in an elastomer matrix, with electromagnetic forms of actuation, to achieve a unique set of properties. Specifically, this materials structure is capable of fast, continuous morphing into a diverse set of continuous, complex 3D surfaces starting from a two-dimensional (2D) planar configuration, with fully reversible operation. Computational, multi-physics modeling methods and advanced 3D imaging techniques enable rapid, real-time transformations between target shapes. The liquid-solid phase transition of the liquid metal allows for shape fixation and reprogramming on demand. An unusual vibration insensitive, dynamic 3D display screen serves as an application example of this type of morphable surface.

  • Ni et al. [133] presented an FIM with shape-morphing capabilities using liquid metal networks embedded in a flexible material, allowing the surface to rapidly and continuously transform into complex 3D shapes as needed.

    “Moreover, Ni et al. [133] presented an FIM with shape-morphing capabilities using liquid metal networks embedded in a flexible material. This design takes advantage of the liquid-solid phase transition of the liquid metal, allowing the surface to rapidly and continuously transform into complex 3D shapes as needed.”

    From Emerging Technologies in Intelligent Metasurfaces: Shaping the Future of Wireless Communications (2026) · cites this paper as [133]

    The Introduction and the Results section on fast 3D shape morphing describe liquid-metal networks embedded in an elastomer and rapid, continuous transformations into complex 3D surfaces. But the Results attribute fast transformations to electromagnetic actuation; the liquid–solid phase transition is used for shape fixation and reprogramming, not to drive rapid morphing.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
