The ability to change shape and control curvature in 3D structures starting from planar sheets can aid in assembly and add functionality to an object. Herein, we convert planar sheets of shape memory polymers (SMPs) into 3D objects with controllable curvature by dictating where the sheets shrink. Ink patterned on the surface of the sheet absorbs infrared (IR) light, resulting in localized heating, and the material shrinks locally wherever the temperature exceeds the activation temperature, Ta…

Curvature arising in shape memory polymer sheets via light absorption

Morphing is a process that spontaneously creates a three-dimensional (3D) curved surface shape from a two-dimensional flat sheet. It has attracted attention in various applications, ranging from

Thermo-mechanical transformation of shape memory polymers from initially flat discs to bowls and saddles

This paper describes the transformation of shape memory polymer (SMP) discs, from flat sheets to complex three-dimensional (3D) shapes, in response to heat generated by localized absorption of

Effects of thermo-mechanical behavior and hinge geometry on folding response of shape memory polymer sheets

Shape memory polymer (SMP) sheets patterned with black ink hinges change shape in response to external stimuli, such as absorbed thermal energy from an infrared (IR) light. The geometry of these

Simultaneous control of Gaussian curvature and buckling direction by swelling of asymmetric trilayer hydrogel hybrids.

This trilayer concept provides a simple way to simultaneously control both the Gaussian curvature and direction of buckling in shape-morphing hydrogels, with advantages for accessing smaller length-scales compared to existing methods.

Stiff or Extensible in Seconds: Light‐Induced Corrugations in Thin Polymer Sheets

Corrugations can dramatically change the effective mechanical properties of a thin sheet. Such alternating ridges and grooves are typically fabricated by mechanical processing. Herein, the ability to

Blueprinting Photothermal Shape‐Morphing of Liquid Crystal Elastomers

An alternative strategy for prescribed shape-morphing by programming the magnitude of stretch ratio in a thin LCE sheet with constant director orientation is developed here and the possibility to achieve complex oscillatory motion driven by uniform illumination of a free-standing patterned sheet is demonstrated.

Self-folding origami of prestrained shape memory polymer by resistive Joule-heating

Shape memory polymers (SMPs) are studied extensively for self-folding origami due to their low cost, large strain recovery and low activation energy. SMPs utilize viscoelastic strain recovery to

Self-folding of polymer sheets using local light absorption

This paper demonstrates experimentally and models computationally a novel and simple approach for self-folding of thin sheets of polymer using unfocused light. The sheets are made of optically

Modelling of shape memory polymer sheets that self-fold in response to localized heating.

A nonlinear finite element analysis (FEA) of the thermo-mechanical shrinking and self-folding behavior of pre-strained polystyrene polymer sheets provides a fundamental understanding of shrinking, self- folding dynamics, and bending angles, and provides design guidelines for origami shapes and structures.

Simple geometric model to describe self-folding of polymer sheets.

A simple method of 'grayscale gel lithography' that relies on a digital micromirror array device (DMD) to control the dose of ultraviolet (UV) light, and therefore the extent of swelling of a photocrosslinkable poly(N-isopropyl acrylamide) (PNIPAm) copolymer film, with micrometer-scale spatial resolution is described.
