Fudan Team Weaves Full Circuits Into Hair-Thin Washable Fibers

A peer-reviewed Nature study details fibers that pack very large-scale integrated circuitry into strands as thin as a human hair.

Overview

  • Researchers at Fudan University led by Peng Huisheng embedded complete electronic circuits inside flexible fibers that can be woven into textiles.
  • Each fiber reaches about 100,000 transistors per centimetre, with a 1 millimetre segment integrating tens of thousands and a one-metre length reaching millions.
  • The strands handle digital and analogue processing and demonstrated neural-style image recognition, with resistors, capacitors, diodes, and transistors built in.
  • The fibers endured more than 10,000 bending and abrasion cycles, stretched up to 30%, twisted 180 degrees per centimetre, survived 100+ wash cycles, withstood 100°C, and bore a 15.6-tonne truck.
  • The team integrated power, sensing, computing, and display in a single fiber and reported laboratory-scale scalable manufacturing, pointing to uses in smart clothing, medical devices, and human‑machine interfaces.
