A geometric twist boosts the power of robotic textiles

Published:20.01.26 — By rethinking how thin metal threads are woven into a flexible textile, EPFL researchers have created a lightweight fabric capable of lifting over 400 times its own weight. The work advances the development of wearables that provide physical assistance without mechanical bulk.

A biodegradable smart sensor to monitor sensitive goods

Published:01.12.25 — Researchers from EPFL, Empa, and CSEM have developed a sustainable smart sensing tag that can be used to signal when shipments of medicines or food have exceeded a safe threshold temperature. It is the first such tag to be fully compostable.
