Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)
Advanced Science, Volume 13, Issue 15, 13 March 2026.Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

FOCUS: A Four‐In‐One Consolidated Unison Strain Sensor with Enhanced Sensitivity
Advanced Science, Volume 13, Issue 14, 9 March 2026.Through a folding transformation that stacks four printed liquid metal sensors into a unified 3D orthogonal construct, FOCUS harnesses complementary bidirectional resistance responses within a Wheatstone bridge. This architecture yields fivefold sensitivity enhancement and 25 µm resolution, overcoming LM sensors’ micro‐strain limitations and enabling ...

High magnification crack-tip field characterisation under biaxial conditions
Fracture and Structural Integrity, 2013 This work presents a novel methodology for characterising fatigue cracks under biaxial conditions. The methodology uses high magnification Digital Image Correlation (DIC) technique for measuring displacement and strain crack-tip fields. By applying micro-

A Standardized Framework for Elastomer Characterization in Soft Robotics
Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.A unified framework addresses inconsistent elastomer property reporting which limits reproducibility and standardization in soft robotics. Systematic testing of ten elastomers (thermosetting, thermoplastic, and a covalent adaptable network) provides quasielastic mechanical properties, viscoelastic parameters, thermal stability, and processing ...

Plasma Processes and Polymers, Volume 23, Issue 3, March 2026.SiOₓ PECVD barrier coating systems on PET lose their barrier function at 5% strain (single loading) or 3% strain (cyclic loading). Simulations reveal that crack offset patterns can reduce permeation by up to 81% through tortuous path effects, though sub‐resolution defects significantly contribute to barrier failure.
