Bioinspired Materials, Designs, and Manufacturing Strategies for Advanced Impact‐Resistant Helmets

open access: yesAdvanced Engineering Materials, EarlyView.
This review explores how bioinspired materials, structures, and manufacturing strategies transform helmet design to achieve enhanced impact resistance. Drawing inspiration from nacre, porcupine quills, beetle exoskeletons, and skull architectures, it highlights advances in auxetic lattices, nanocomposites, and functionally graded foams.

3D‐Printable Near‐Infrared‐Responsive Microscale Cantilever made of the Composite Consisting of Ceramic Particles and Graphene Flakes

open access: yesAdvanced Engineering Materials, EarlyView.
A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Enhanced Optogenetic Stimulation of Retinal Ganglion Cells With Assistive Electric Stimulation for Low Optical Power Artificial Vision

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering
High optical power of optogenetic stimulation may cause phototoxicity during chronic application. To lower the optical power, a hybrid approach which combines optogenetic and electric modalities has been proposed.

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the
