Abstract Freeze casting is a versatile technique for organizing low‐dimensional building blocks into ordered porous structural materials. However, the freeze‐casting fabrication of materials with robust and topologically elastic skeleton to withstand harsh conditions challenging. Herein, silanized ultra‐homogeneous nanocomposite aerogel fabricated using gelation‐constrained strategy. Diverging from traditional methods employing solution precursor, approach involves process utilizing rational‐designed supramolecular hydrogel as quasi‐solid precursor. The within hydrogel, enclosed in dense hydrogen‐bonded network, effectively mitigate secondary agglomeration caused by ice crystallization concentration enrichment during freeze‐casting. By forming cellular an interconnected nanoparticle resulting aerogels exhibit exceptional mechanical elasticity retaining over 98% height after 10 000 compression cycles, along superior electrical properties showing 78.9% increase conductivity compared conventional aerogels. Wearable piezoresistive sensors these demonstrate outstanding force sensing capabilities, broad linear range (0–17.6 kPa) high sensitivity (1.32 kPa −1 ). When integrated intermediate layer protective garments, offer insulation fire resistance, enabling them endure like repetitive extreme deformations, exposure high‐temperature flames, water‐erosion damages.

Structure and Wiring Optimized TT/MT Double‐Helical Fiber Sensors: Fabrication and Applications in Human Motion Monitoring and Gesture Recognition

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 4, 2025

Abstract A fibrous flexible sensor, with its small size, minimally burdens the human body, ranking among most user‐friendly sensors. However, application is often limited by damage caused electrode movement, as sensors are typically attached to joints, which can be greatly alleviated placing two electrodes on same side. Inspired hydrogen bonds in double‐helical structure of DNA, design commonly found and applied fiber‐based batteries supercapacitors into through coaxial wet‐spinning further treatment.
