A research team, led by professor Sungwon Lee from DGIST's Department of Physics and Chemistry, has developed a novel breathable smart sensor capable of real-time hazardous gas detection on masks. This technology, known as hierarchical graphene nanowall nanomesh, enhances the sensing performance of wearable gas sensors for extended wear in hazardous environments.
The sensor, now applied to a wearable mask platform, maintains high breathability and flexibility while enabling long-term gas monitoring. This innovative approach, called nano-on-nano technology, directly forms functional nanostructures on polymer nanomeshes, improving gas sensing performance by controlling the movement of gas molecules within nanostructures.
This breakthrough could extend the application of the technology to various breathable wearable electronic devices.
