Laser writing of conductive textile fiber

Direct laser writingGrapheneSmart textileWearable devices

Introduction

The present proposal relies on a technology able to selectively laser-write textile fibers in order to induce conductive path on them  overcoming the actual limitations in the production of fibers-shaped electrodes. The laser-written fibers can be exploited in several kind of wire-shaped device for electronic textile applications ranging from wearable energy storage devices to sensors.

Technical features

This technolology is based on a direct laser writing system and exploits the incident power of the laser to induce a conversion of fiber material into graphene-based conductive material with tunable chemico-physical properties depending on the composition of the fiber and laser writing parameters. Once written the fibers exhibit a local conductivity useful for  textile-based electronic device.
