Published: March 11, 2024

Achieving flexible electronics with comfort and durability comparable to traditional textiles is one of the ultimate pursuits smart wearables. Ink printing desirable for e-textile development using a simple inexpensive process. However, fabricating high-performance atop good dispersity, stability, biocompatibility, wearability high-resolution, large-scale manufacturing, practical applications has remained challenging. Here, water-based multi-walled carbon nanotubes (MWCNTs)-decorated liquid metal (LM) inks are proposed carbonaceous gallium-indium micro-nanostructure. With assistance biopolymers, sodium alginate-encapsulated LM droplets contain high carboxyl groups which non-covalently crosslink silk sericin-mediated MWCNTs. E-textile can be prepared subsequently via technique natural waterproof triboelectric coating, enabling flexibility, hydrophilicity, breathability, wearability, conductivity, excellent versatility, without any artificial chemicals. The obtained used in various designable patterns circuits. Multi-sensing recognizing complex human motions, breathing, phonation, pressure distribution demonstrated repeatable reliable signals. Self-powered energy-harvesting capabilities also presented by driving electronic devices lighting LEDs. As proof concept, this work provides new opportunities scalable sustainable way develop novel wearable clothing future commercial applications.

Inter-Skeleton Conductive Routes Tuning Multifunctional Conductive Foam for Electromagnetic Interference Shielding, Sensing and Thermal Management

Nano-Micro Letters, Journal Year: 2024, Volume and Issue: 17(1)

Published: Oct. 28, 2024

Abstract Conductive polymer foam (CPF) with excellent compressibility and variable resistance has promising applications in electromagnetic interference (EMI) shielding other integrated functions for wearable electronics. However, its insufficient change amplitude of compressive strain generally leads to a degradation performance during deformation. Here, an innovative loading strategy conductive materials on is proposed significantly increase the contact probability area components under compression. Unique inter-skeleton films are constructed by alginate-decorated magnetic liquid metal polymethacrylate hanged between skeleton (denoted as AMLM-PM foam). Traditional point skeletons compression upgraded planar films. Therefore, reaches four orders magnitude Moreover, can improve mechanical strength foam, prevent leakage scattering EM wave. strain-adaptive EMI shows compression-enhanced effectiveness, solving problem traditional CPFs upon The upgrade response also enables achieve sensitive pressure sensing over wide range compression-regulated Joule heating function.
