Published: May 15, 2025

Abstract Developing methods to non-destructively deposit conductive materials onto existing objects can enhance their functionalities on-demand. However, designing and creating such structures accommodate diverse shapes surface textures of pre-fabricated remains challenging. We report an on-demand printing strategy for substrate-less, conducting microfiber patterns that be adaptively deposited a wide range objects, including daily-use stationery, tools, smartwatches, unconventional like porous graphene aerogels. Solution-drawn microfibers are directly the object in semi-wet state upon synthesis, enabling seamless fiber-object integration single step. The design format tuned adapt target ensuring compatibility with user-specific applications. These air-permissive, highly transparent layers minimally obstruct original appearance functions while equipping them additional sensing, energy conversion, electronic connectivity capabilities.

Piezoresistive Porous Composites with Triply Periodic Minimal Surface Structures Prepared by Self-Resistance Electric Heating and 3D printing

Published: March 4, 2024

Three-dimensional flexible piezoresistive porous sensors have been used in health diagnosis and wearable devices. By utilizing 3D printed sacrificial mold casting with highly conductive polymer composites, high conductivity complex structures were achieved. Traditional composites are usually heated using external heat sources, which time energy consuming. However, this study, triply periodic minimal surface (TPMS) manufactured self-resistance electric heating by the nature of polymers. The designed based on Diamond (D), Gyroid (G), I-WP (I) unit cells TPMS. use has improved compression performance response structures. Among these structures, D-based structure exhibited maximum strain (61 %), a corresponding resistance value 0.97, increased 10.26 % compared to that sources. This study offers new perspective designing optimizing materials specific functionalities, particularly realm portable sensors.
