Wearable health bands provide essential data on various health metrics, including sleep efficiency, oxygen saturation, and stress levels, among others. Wearing them during the day when you’re active is acceptable, but they can become uncomfortable when worn while you’re asleep. To address this issue, Sleepal, by Ningning Li, Haorong Liu, and Jiantao, offers a contactless alternative to wearable health trackers.
it’s a bedside lamp that passively monitors your sleep via a built-in 60 GHz millimeter-wave radar that reflects from your chest with high precision. The radar detects breathing, heartbeat, and even subtle movements, which are then translated into sleep data.
Sleepal monitors your body’s positions during sleep, while its built-in microphone detects snoring patterns to help you find the most comfortable and restful sleep. Its AI system operates with up to three trillion operations per second to provide accurate real-time analysis of sleep signals.
The lamp works with a WI-FI-connected companion mobile app, which stores historical trends and sleep data. It shows your sleep score, sleep efficiency, sleep duration, breathing score, sleep stages, sleep regularity, heart rate, and respiration rate. The app also provides insights into how the surrounding noise, humidity, temperature, and light can affect your sleep.
Moreover, this lamp also automatically adjusts the light output to support circadian rhythms. It dims at night to slowly ease you into sleep and gradually brightens in the morning to wake you up gently.
Conveniently, Sleepal is Matter-certified, making it compatible with Apple Home, Amazon Alexa, and Google Home for voice or remote controls. You can connect it with your home’s smart devices (turn on the humidifier or close the blinds when you’re asleep). Meanwhile, a privacy button controls data collection by physically disconnecting sensors at the circuit level.
