Consumer wearables count what is easy to count. Steps, hours, beats. None of it tells you whether your body is changing.
Three sensors, one picture
Dry-electrode ECG reads the heart's electrical signal. Multi-wavelength PPG watches blood flow. Precision thermistors track your temperature against its own baseline.
Each stream alone is noisy. Fused, they show vascular, autonomic, and metabolic trends — the research problem is the fusion, not the sensors.
Your baseline, not the population's
A single reading from a wrist means little, and pretending otherwise is how wearables overclaim.
A drift from your own baseline over weeks is a different kind of signal. Smaller claim, more useful truth: metabolic response trends, temperature deviations, accumulating stress load.
Where Lunas comes in
Readings would land on the same Lunas timeline as your labs and records, where Stethos can see them side by side.
A temperature drift next to last month's blood work is not a diagnosis. It is a better question to bring to your doctor — and that is the product.
What this deliberately does not do
- No hardware has shipped — this is research, not a product
- Not a medical device: no diagnosis, no regulatory clearance
- Wellness trends only — nothing here detects or monitors disease
- The architecture is exploratory and expected to change
