Deep reactive ion etching of auxetic structures: present capabilities and challenges [PDF]
, 2014 Auxetic materials (or metamaterials) have negative Poisson ratios (NPR) and display the unexpected properties of lateral expansion when stretched, and equal and opposing densification when compressed. Such auxetic materials are being used more frequently

Autonomous inverse encoding guides 4D nanoprinting for highly programmable shape morphing
International Journal of Extreme ManufacturingHighly programmable shape morphing of 4D-printed micro/nanostructures is urgently desired for applications in robotics and intelligent systems. However, due to the lack of autonomous holistic strategies throughout the target shape input, optimal material

Blueprinting Photothermal Shape‐Morphing of Liquid Crystal Elastomers
Advanced Materials, 2020 AbstractLiquid crystal elastomers (LCEs) are an attractive platform for dynamic shape‐morphing due to their ability to rapidly undergo large deformations. While recent work has focused on patterning the director orientation field to achieve desired target shapes, this strategy cannot be generalized to material systems where high‐resolution surface ...
