Researchers from the University of Cambridge have developed innovative 'smart pyjamas' that incorporate printed fabric sensors to monitor sleep disorders by detecting subtle skin movements.

With over 60% of adults experiencing poor sleep quality, which can lead to significant health issues and economic losses, the need for effective sleep monitoring solutions has never been more critical.

These smart pyjamas are an evolution of earlier research on a smart choker designed for speech impairments, optimizing graphene-based sensors for breath analysis during sleep.

Current sleep monitoring methods, such as polysomnography, are often expensive and impractical for long-term home use, highlighting the demand for more accessible alternatives.

The smart pyjamas offer a promising solution, as existing home sleep tests and wearables tend to be uncomfortable or inadequate for accurately monitoring disordered sleep.

Utilizing a lightweight AI algorithm, the integrated sensors can accurately identify six different sleep states with an impressive 98.6% accuracy, effectively filtering out normal sleep movements.

The AI model, known as SleepNet, processes signals from the sensors to detect various sleep states, including nasal and mouth breathing, snoring, and different types of sleep apnea.

Designed for durability, the sensors can withstand regular washing and support wireless data transfer to smartphones or computers, enhancing user convenience.

This wireless capability facilitates secure data sharing with healthcare providers, enabling users to monitor their sleep at home and discuss potential issues.

The smart pyjamas could significantly benefit the millions in the UK suffering from sleep disorders, allowing them to track their sleep patterns and the impact of lifestyle changes.

Future applications of this sensor technology may extend to monitoring other health conditions and even baby monitoring, with ongoing discussions with various patient groups.

The research has received support from the EU Graphene Flagship, Haleon, and the Engineering and Physical Sciences Research Council (EPSRC), underscoring its scientific significance.
