Multistable energy landscapes for adaptive microscopic machines
Melody Xuan Lim, Zexi Liang, Gabriel Alkuino +5
The past few years have seen great strides in our ability to build synthetic microscopic machines. However, the function of such machines is often controlled directly by externally…
Programming evolution of geometry in shape-morphing sheets via spatiotemporal activation
Daniel Duffy, Itay Griniasty, John Biggins +1
Shape-programmed sheets morph from one surface into another upon activation by stimuli such as illumination, and have attracted much interest for their potential engineering applic…
Bifurcation instructed design of multistate machines
Teaya Yang, David Hathcock, Yuchao Chen +4
We propose a novel design paradigm for multistate machines where transitions from one state to another are organized by bifurcations of multiple equilibria of the energy landscape…
Discontinuous metric programming in liquid crystalline elastomers
Tayler S. Hebner, Riley G. A. Bowman, Daniel Duffy +6
Liquid crystalline elastomers (LCEs) are shape-changing materials that exhibit large deformations in response to applied stimuli. Local control of the orientation of LCEs spatially…
Incorporating tunability into a universal scaling framework for shear thickening
Meera Ramaswamy, Itay Griniasty, James P Sethna +2
Recently, we proposed a universal scaling framework that shows shear thickening in dense suspensions is governed by the crossover between two critical points: one associated with f…
Universal scaling of shear thickening transitions
Meera Ramaswamy, Itay Griniasty, Danilo B. Liarte +6
Nearly all dense suspensions undergo dramatic and abrupt thickening transitions in their flow behaviour when sheared at high stresses. Such transitions occur when the dominant inte…
Multi-valued inverse design: multiple surface geometries from one flat sheet
Itay Griniasty, Cyrus Mostajeran, Itai Cohen
Designing flat sheets that can be made to deform into 3D shapes is an area of intense research with applications in micromachines, soft robotics, and medical implants. Thus far, su…
Curved geometries from planar director fields - Solving the two-dimensional inverse problem
Itay Griniasty, Hillel Aharoni, Efi Efrati
Thin nematic elastomers, composite hydrogels and plant tissues are among many systems that display uniform anisotropic deformation upon external actuation. In these materials, the…
