Mechanics of disordered auxetic metamaterials [PDF]
, 2018 Auxetic materials are of great engineering interest not only because of their fascinating negative Poisson's ratio, but also due to the possibility to increase by design the toughness and indentation resistance.

Small, EarlyView.This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

Applied Research, Volume 5, Issue 5, October 2026.The ballistic resistance of auxetic re‐entrant honeycomb structures can be significantly improved through geometric tailoring and structural reinforcement. Vertical and horizontal stiffening ribs enhanced the ballistic performance, increasing the energy absorption efficiency by 119.45% and the projectile velocity reduction by 281.36%, ultimately ...

Advanced Healthcare Materials, Volume 15, Issue 35, 18 September 2026.This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...
