A Sustainable-by-Design Wearable Sweat Sensor via Compostable Microfluidics and Laser-Induced Graphene Electrodes for Real-Time Monitoring of Physical Exercise

This study presents a biodegradable wearable sweat sensor that combines laser-induced graphene electrodes engraved on chitosan/paper substrates with a compostable microfluidic platform for continuous monitoring of sweat ionic strength and sweat rate during exercise. A dual-level life cycle assessment at the device and electrode levels shows lower environmental impacts than conventional PDMS- and metal-based sensor designs across EF 3.1 impact categories.
