Revolutionizing Home Sleep Monitoring: A Deep Dive into the Future with Washable Smart Pajamas
Imagine a world where monitoring your sleep is as simple and agreeable as slipping into pajamas—no cumbersome machines, no intrusive sensors. With the advent of washable smart pajamas, this futuristic vision is becoming a reality. Researchers from the University of Cambridge and Chinese universities Capital Medical University and Beihang University have developed a groundbreaking solution for home sleep monitoring: washable, skin-compatible smart pajamas.
This innovative technology utilizes graphene sensors embedded within the garment to capture subtle skin strain signals, providing a cozy and convenient option to conventional, frequently enough cumbersome, methods. The system requires no special positioning or skin readiness, making it ideal for long-term home use. The pajamas monitor sleep by detecting vibrations at the extrinsic laryngeal muscle, induced by physiological vibrations from areas like the velum, oropharynx, tongue, and epiglottis. A six-channel strain sensor array, printed onto the collar, captures these vibrations. The strongest signal is then processed by a deep learning neural network, SleepNet, to analyze sleep patterns.
The importance of this advancement is significant.”Poor sleep has huge effects on our physical and mental health, which is why proper sleep monitoring is vital,” explained Professor Luigi Occhipinti from the Cambridge Graphene Center, who led the research. “However,the current gold standard for sleep monitoring,polysomnography or PSG,is expensive,elaborate and isn’t suitable for long-term use at home.”
Existing home sleep tests frequently focus on single conditions and are bulky or uncomfortable. Smartwatches, while more comfortable, only infer sleep quality and aren’t effective for accurately monitoring disordered sleep. Occhipinti emphasized the need for a solution that is comfortable and easy to use every night, but is accurate enough to provide meaningful details about sleep quality.
Building on previous work with a smart choker for speech-impaired individuals, the team redesigned the graphene-based sensors for breath analysis during sleep, enhancing sensitivity. “Thanks to the design changes we made, the sensors are able to detect different sleep states, while ignoring regular tossing and turning,” said Occhipinti. “The improved sensitivity also means that the smart garment does not need to be worn tightly around the neck, which many people would find uncomfortable. Provided that the sensors are in contact with the skin, they provide highly accurate readings.”
SleepNet, the machine learning model, identifies sleep states including nasal breathing, mouth breathing, snoring, teeth grinding, central sleep apnea (CSA), and obstructive sleep apnea (OSA). Occhipinti highlighted the efficiency of the AI: We pruned the AI model to the point where we coudl get the lowest computational cost with the highest degree of accuracy. This way we are able to embed the main data processors in the sensors directly.
This lightweight AI allows for processing on portable devices without needing a connection to computers or servers.
Testing on healthy patients and those with sleep apnea showed the pajamas accurately detected a range of sleep states with 98.6% accuracy. A special starching process enhances sensor durability, allowing for machine washing. The latest version also features wireless data transfer to smartphones or computers.
The implications are far-reaching. “Sleep is so critically crucial to health, and reliable sleep monitoring can be key in preventative care,” said Occhipinti. “Since this garment can be used at home, rather than in a hospital or clinic, it can alert users to changes in their sleep that they can then discuss with their doctor. Sleep behaviors such as nasal versus mouth breathing are not typically picked up in an NHS sleep analysis, but it can be an indicator of disordered sleep.”
Future applications are being explored, including baby monitoring, and the researchers are working to further improve sensor durability for extended use. The development of these smart pajamas represents an important advancement in accessible and accurate home sleep monitoring, possibly impacting millions affected by sleep disorders.
