Contactless Sleep Sensing vs Wearables Compared
Wearables estimate sleep from movement and heart rate, under-mattress sensors from vibration, and radar from reflected signals. All are best for trends, not diagnosis.
Key points
- Wearables. Watches and rings measure movement and pulse.
- Under-mattress sensors. These sense movement, breathing and heart rate through the mattress without a device on the body.
- Radar. Bedside radar units sense breathing and movement from a distance.
- What it means for you. Pick the form you will actually use every night and focus on trends.

Wearables
Watches and rings measure movement and pulse. They are convenient and good at timing, weaker at stages.
Under-mattress sensors
These sense movement, breathing and heart rate through the mattress without a device on the body. They suit people who dislike wearing things.
Radar
Bedside radar units sense breathing and movement from a distance. They are newer and mostly vendor-validated.
What it means for you
Pick the form you will actually use every night and focus on trends. See a doctor for suspected sleep disorders.
