SMK Launches Milweb™ Sleep : Revolutionary Non-Contact Sleep Monitoring Solution - No internet connection required. Simply place it beside the bed. - Product News

 SMK has developed  Milweb™ Sleep, a non-contact sleep depth monitoring solution that uses millimeter-wave radar sensing technology. This next-generation technology precisely estimates sleep quality when placed beside your bed. It automatically provides an optimal sleep environment tailored to the user in coordination with smart home appliances. 
In recent years, the impact of sleep quality on health and quality of life has received widespread recognition, resulting in the rapid growth of the sleep technology market. However, conventional sleep monitoring devices are primarily wearable ones and can be burdensome for many users. Additionally, products that require cloud connectivity have encountered issues related to communication environments and the management of personal information. Against this backdrop, we have worked to develop a new solution that enables more comfortable and secure sleep measurement.

Milweb™ Sleep uses 24GHz millimeter-wave radar technology to detect subtle body movements with high sensitivity and without contact. This provides a level of comfort and convenience that is unattainable with wearable sensors. Furthermore, our proprietary sleep estimation algorithm, developed by incorporating insights from sleep and vital sign specialists, visualizes the four stages of sleep—awake, REM sleep, light sleep, and deep sleep—with accuracy comparable to an electroencephalograph. This product does not require a cloud connection. It can determine sleep depth in real time using only the sensor. Therefore, it is not dependent on a network environment and does not transmit personal information externally.

Additionally, Milweb™ Sleep features Bluetooth® communication capabilities and complies with the international standard “Matter.” This enables interoperability with smart home devices across manufacturers, facilitating advanced home automation such as:

  • Gradually dimming lights when you fall asleep
  • Opening window shades at the optimal time for waking up

This goes beyond simple sleep visualization, helping to create a comfortable and healthy sleep environment tailored to each individual user.
We offer Milweb™ Sleep as a complete ODM/OEM solution that includes a millimeter-wave radar sensor, a sleep estimation algorithm, and smart home integration features. This will make your products more competitive in the rapidly growing sleep technology market.

    Product NameMilweb™ Sleep
    Features
    1. Non-contact, no wear required
      Uses a 24 GHz millimeter wave radar to detect even the slightest body movements. Simply place it beside the bed to activate its high sensitivity. Maintains accuracy even through bedding, providing a level of comfort and convenience that conventional sensors cannot offer.
    2. Sleep detection algorithm
      Our proprietary algorithm accurately estimates and visualizes the four stages of sleep: awake, REM sleep, light sleep, and deep sleep.
    3. Real-time processing
      No cloud connection is required. The sensor independently and instantly determines sleep depth. Designed to be independent of network environments and considerate of privacy.
    4. Matter Compatible
      Compliant with the international standard Matter, enabling connectivity with smart home devices from different manufacturers. Its integration with lighting, window shades, and other devices enables automatic environmental adjustments based on the state of sleep, promising broad applications in the smart home sector.
