Under the project, ‘LIG-based Wearable Seismorespirators for emulating clinical respiratory examination’, we aim to usher in a new era of respiratory monitoring with the development of Seismorespirators — next-generation integrated devices designed to mimic the nuanced clinical assessments performed during a physical examination. These systems will merge inertial, vibroacoustic and stretch-sensing capabilities into a single soft, flexible platform, enabling a far more detailed, continuous and non-invasive evaluation of breathing patterns than currently possible with conventional tools.

At the heart of this effort lies our breakthrough in laser-induced graphene (LIG)–based soft and stretchable sensors. These lightweight, skin-conforming sensors can detect subtle respiratory movements and acoustic signatures with exceptional sensitivity. Having already demonstrated their potential in breath-monitoring applications, they now form a core technological pillar for the Seismorespirator platform.

By combining advanced nanomaterials, innovative sensor engineering and human-centred design, this project seeks to create a device that not only measures respiration, but understands it — capturing the micro-vibrations, motion dynamics and stretch variations that clinicians rely on to diagnose and track respiratory health. The result will be a powerful, flexible tool poised to transform how respiratory assessment is performed outside traditional clinical settings, from home monitoring to wearable health systems.
