Why it works.
The sensing inside Rhem, explained plainly. What it measures, how it keeps watch, and an honest line about what it is not.
One touch. Five signals.
A hand resting on top is the whole ritual. The sensors do the rest.
The morning reading.
Blood pressure
Cuffless and guided on the device: rest your fingers, no arm squeeze, and read the result in seconds. Rhem cares about the trend as much as the number.
EKG & heart rate
The same resting touch traces the heart's electrical signal, so rate and rhythm come from the source rather than an estimate.
Oxygen & temperature
Blood oxygen and body temperature round out the picture, taken in the same seconds as everything else. Nothing to wear, nothing to charge.
The trendline
Rhem learns what is normal for one person. When a reading drifts from that baseline, the change is what gets flagged, early and in plain language.
Sensing without seeing.
Between readings, millimeter-wave radar keeps watch. It reads motion and breathing as reflected signal, so a fall registers as a pattern, not a picture. It works in the dark, through the night, with no camera in the room for that job.
Kept at home.
A dedicated compute module runs Rhem's wellness AI on the device, so readings are interpreted in the room where they were taken. Health data does not have to leave the home to be useful.
And the honest line: Rhem is a wellness and safety companion, not a certified medical device. It is built for awareness and better conversations with professionals, not for diagnosis.
