Multistrand Twisted Triboelectric Kevlar Yarns for Harvesting High Impact Energy, Body Injury Location and Levels Evaluation

Advanced Science, Год журнала: 2024, Номер 11(21)

Опубликована: Март 15, 2024

Abstract Developing ultrahigh‐strength fabric‐based triboelectric nanogenerators for harvesting high‐impact energy and sensing biomechanical signals is still a great challenge. Here, the constraints are addressed by design of multistrand twisted Kevlar (MTTK) yarn using conductive non‐conductive fibers. Manufactured twisting process, MTTK offers superior tensile strength (372 MPa), compared to current yarns. In addition, self‐powered impact fabric patch (SP‐ISFP) comprising signal acquisition, processing, communication circuit, yarns integrated. The SP‐ISFP features withstanding (4 GPa) sensitivity response time under high condition (59.68 V GPa −1 ; 0.4 s). Furthermore, multi‐channel smart bulletproof vest developed array 36 SP‐ISFPs, enabling reconstruction mapping assessment body injury location levels real‐time data acquisition. Their potential reduce injuries, professional security, construct multi‐point personal vital signs dynamic monitoring platform holds promise.

Flexible Fiber‐Shaped Supercapacitors: Structures, Materials, Fabrication Methods, and Applications

Interdisciplinary materials, Год журнала: 2025, Номер unknown

Опубликована: Апрель 13, 2025

ABSTRACT The advent of wearable electronics has generated considerable interest in the development fiber‐shaped supercapacitors (FSCs). FSCs have several applications, such as integration into power fabrics for modular energy storage, coupling with specific devices, forming composite fibers, and combining energy‐harvesting fibers to develop integrated storage‐usage fabrics. This review provides a comprehensive overview based on their fundamental principles, detailing various structural configurations (e.g., parallel, wrapped, twisted, coaxial) substrate materials carbon‐based, polymeric, metallic fibers), along strategies enhancing electrochemical mechanical performance. Furthermore, it outlines large‐scale fabrication techniques, wet spinning, synchronous coupling, direct ink writing, thermal drawing. identifies challenges currently facing research suggests directions future development.
