Area of Science:

  • Materials Science
  • Mechanical Engineering
  • Biomimicry

Background:

  • Vertebrates possess articular structures for motion, while invertebrates rely on body deformability for survival.
  • Existing materials lack the ability to switch between these contradictory mechanical strategies.
  • Adaptable materials are needed for diverse dynamic applications requiring both rigidity and flexibility.

Purpose of the Study:

  • To introduce a novel material with dual mechanical modes.
  • To enable on-demand switching between extreme stiffness states.
  • To explore applications in multimodal kinematics and smart functional materials.

Main Methods:

  • Spatial micro-water molecule manipulation, termed engineering on variable occupation of water (EVO).
  • Development of a transparent, homogeneous soft material (110 kPa).
  • Reversible conversion to an opaque material with a mechanical gradient (1 GPa to 1 MPa) via on-demand switching.
  • Intensive theoretical analysis to design a spatial transformation scheme.

Main Results:

  • Successful realization of a material with dual mechanical modes exhibiting extreme stiffness differences.
  • Demonstration of reversible transformation from a soft (110 kPa) to a stiff (1 GPa to 1 MPa) state.
  • EVO gel achieved kinematic motion planning capabilities.

Conclusions:

  • The engineering on variable occupation of water (EVO) approach enables the creation of materials with tunable mechanical properties.
  • This technology facilitates multimodal kinematics and adaptable mechanical behaviors.
  • The developed smart material holds significant promise for future dynamic applications.
