On the Origins of Out‐of‐Plane Auxetic Response in Paper

open access: yesphysica status solidi (b), EarlyView.
Paper can be auxetic! Paper can exhibit a range of out‐of‐plane Poisson's ratio (PR) values. Examining handsheets made from hardwood (HW) and softwood (SW) fibers, of a variety of weights (1, 3, or 5 g) and refining degrees (none, R, or R+), showed that the sign and magnitude of PR can be finely controlled by modifying network parameters.

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

open access: yesResponsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...
