# [Smart pyjamas: a sleep monitoring revolution](https://www.ibsafoundation.org/en/blog/smart-pyjama-sleep-monitoring-revolution)

Game-changing sleep-monitoring pyjamas from the University of Cambridge are here to help people sleep well. A team of researchers has developed a smart device to detect sleep disorders accurately and in a non-invasive way using graphene ink and artificial intelligence.

**Polysomnography** sensors and at least one night in hospital are currently required to assess **sleep quality**. But in the not-too-distant future, assessment could be done in the comfort of your own home with a pair of **smart pyjamas**.   
Scientists at the **Graphene Centre of the University of Cambridge**, led by Italian researcher Luigi Occhipinti, have developed a prototype that is extremely **reliable, comfortable and easy to use**.   
This device could pave the way for a new generation of **instruments for monitoring biological functions**. As we know, there are other wearable “devices” out there that can provide information on sleep. But such devices** can only infer sleep quality** and aren’t effective when it comes to **accurately detecting disorders**, according to the British researchers.

### **A “collar” to analyse sleep qualityUn “collare” per analizzare la qualità del sonno**

As reported in the [scientific journal ***PNAS***](https://www.pnas.org/doi/10.1073/pnas.2420498122), the pyjamas are made of a **washable fabric** and a series of **state-of-the-art sensors**. Their distinctive feature is a **soft collar** that uses **graphene ink** to identify **six different types of sleep**, from normal to disordered.

The researchers had [previously developed a similar device](https://www.cam.ac.uk/research/news/smart-choker-uses-ai-to-help-people-with-speech-impairment-to-communicate) for people with **speech disorders**, such as **stroke **or** laryngeal surgery** patients. They adapted the device, successfully developing an effective system for **sleep monitoring and diagnosing sleep-related disorders**.

The **sensors embedded in the collar **detect **changes in skin resistance **caused by breathing, without the need to be fitted tightly to the body. This means that the device even works when the **pyjamas are worn loosely** around the neck and chest.

****Monitoring sleep with artificial intelligence****

One of the **key features **that make this device effective is the **artificial intelligence **programme **SleepNet**, which **doesn’t need to be connected to a computer** or mobile phone.   
The **algorithm** accurately identifies **six sleep behaviours** (normal, mouth breathing, **snoring**, **teeth grinding **and **two types of sleep apnoea**), while ignoring accidental situations such as coughing or involuntary vocalisations.

When put to the test, **SleepNet **showed enormous potential, **identifying sleep states correctly in more than 98% of cases**. What’s more, the device is **affordable** and can be **reused over and over again**.  
It is estimated that around **60% of adults **experience **sleep problems**, with a **considerable number of **working days** **lost every year** as a result**. Moreover, it has been proven that people who** sleep badly** are at **greater risk of conditions** like high blood pressure and depression.  
Understanding how to improve sleep quality simply by wearing smart pyjamas could help many people feel better.
