Research project: Design and characterization of flexible gas sensors for wearable electronics application

Currently Active: 
Yes

Recent advances in material technology has demonstrated great potential for new applications in flexible electronics. A wide range of application such as flexible displays, mechanical sensors (strain, pressure, motion etc.), and bio-electrical sensors (galvanic skin response, EEG, ECG, etc.). Most of these sensors consists of an active sensing layer and a flexible substrate.

Recent advances in material technology has demonstrated great potential for new applications in flexible electronics. A wide range of application such as flexible displays, mechanical sensors (strain, pressure, motion etc.), and bio-electrical sensors (galvanic skin response, EEG, ECG, etc.). Most of these sensors consists of an active sensing layer and a flexible substrate. Typically, the active sensing layer are made from either conductive polymer, metallic nanoparticles, or carbon-based materials. Our previous research work on nanocrystalline graphite and nanocrystalline graphene reveals the potential of using carbon film with high defect density in redox gas sensing and humidity sensing. Hence, this research aims to explore the possibility of using carbon based flexible sensors as gas sensors for wearable electronics application.
