Respiratory motion
Breathing causes small movements that radar can detect and signal processing can analyze.
The technology behind the ease
Small movements tell a bigger story.
Radar sends radio waves into a space and measures their reflections. Tiny changes in those reflections reveal movement—even motion too subtle to see.
From motion to meaning
Contactless, from the start.
Our platform combines radar hardware, embedded processing, and signal analysis. We’re developing ways to distinguish breathing-related motion, heart-related motion, and larger body movements, then make the resulting patterns understandable.
Placement, distance, posture, movement, and other people can affect signal quality. Our testing investigates those conditions rather than assuming a perfectly still subject.

Product details
Designed with everyday spaces in mind.
Final Sleep product dimensions and package contents are still being confirmed. We’ll publish the unit size and included mounting and power accessories before availability.

What we’re studying
One sensing approach.
Several kinds of motion.
Heart-related motion
We’re studying much smaller motion associated with cardiac activity. Performance is still being evaluated.
Presence and movement
Radar reflections help identify where motion is happening and how it changes over time.
Multiple-person sensing
Development work explores separating motion signals from more than one person in a shared space.
Engineering, with context
Proof comes from testing.
We’re building a documented understanding of performance across overnight recordings, development hardware, and real environments. Development results are not clinical validation.
Explore research and collaborationHow will Signal Smith protect my information?
Product security and data handling are still being finalized. Before Sleep is available, we’ll explain in plain language what the device processes, whether information is sent over the internet, where it is stored, and who can access it. Core radar motion sensing does not require a camera.
Where can I find specifications and validation results?
We’ll publish verified specifications and appropriately qualified results as they become available. For a research discussion, contact our team through the Research & Partners page.
