🎓 Congratulations to Dr. Hritwick Banerjee from the Laboratory of Photonic Materials and Fiber Devices (FIMAP) of Materials Science and Engineering at EPFL for successfully defending his PhD thesis “Functional Soft Fibers and Textiles: Multi-Material Approaches for Actuation and Sensing” under the supervision of Prof. Fabien Sorin.
This work presents soft, smart fibers: stretchy threads that can sense, actuate, and communicate, fabricated with a scalable multimaterial thermal drawing process. We developed magnetic, muscle-like fibers for remote actuation; conductive fibers that provide real-time motion tracking; electromagnetic fibers that deliver precise, tunable forces; heat-responsive liquid crystal elastomer fibers that reversibly contract and relax; and color-changing photonic fibers that report strain optically. Woven into textiles, these threads integrate sensing and actuation in lightweight, flexible formats. They enable interactive rehabilitation tools, intelligent garments, and gentle soft robotic systems, and they establish a manufacturable path toward next-generation biomedical devices and safer human-machine interactions.
