The technology
Real data. From the source.Real clarity.
Femora is the only wearable that continuously measures reproductive health signals directly at the source — not inferred, not estimated.
Backed by science. Built for women.
What we measure
The insights you see start with the signals we measure.
Vaginal pH
Detect meaningful changes earlier.
A continuous read of your intimate environment, sensitive to the shifts that matter and quiet about the ones that don't.
Discharge patterns
Understand your cycle with more confidence.
Cervical fluid is the cycle's live broadcast. Femora reads its rhythms from the fabric layer, automatically.
Skin temperature
Reveal your personal monthly rhythm.
The classic fertility signal, finally collected the way it always should have been — while you sleep, without a thermometer.
Heart rate
See how your body responds.
Resting heart rate rises and falls with your cycle's hormonal weather. Femora captures the curve, not a guess.
Heart rate variability
Understand your resilience and wellbeing.
HRV reflects the load your body is carrying — and how it interplays with your cycle across the month.
Engineering
Deep technology, built for real life.
Yarn-based sensing
Conductive fibers are drawn into textile-grade yarns that respond to physiological changes around them — softness first, electronics second.
Knitted in, not glued on
Sensing zones are knitted directly into the garment structure. No coatings that crack, no patches that peel, nothing that changes how the fabric feels.
Smart hardware
A coin-sized unit snaps magnetically onto the waistband, processes readings locally, and encrypts them before anything is transmitted.
AI that understands you
Models trained on millions of real-world wear minutes translate five raw signals into personal patterns — not population averages.
From signal to insight
Your reproductive health. Measured at the source. No approximations.
Clarity starts with understanding your body.
Continuously measure
Overnight and all day, five signals stream from fabric to unit without any action from you.
Securely connect
Encrypted, on-device processing and Bluetooth sync — your raw data never touches a third party.
Reveal hidden patterns
The app aligns your signals across cycles to surface what repeats and what changed.
Deliver personal insights
Predictions and explanations written for your body — with the confidence to match.
Everyday life
Designed to fit your life, so you can focus on what matters.
Wear it. Forget it's there.
Seamless, breathable cotton with nothing that shows under clothing.
Built for intimate health.
Designed at the source — not adapted from a wrist or a finger.
Wear for days.
Up to 4 days of battery, an hour to recharge.
Fits into your life.
No routines to change. No extra steps. Just put it on and go.
Powerful enough to change healthcare. Simple enough to forget you're wearing it.
Research & compliance
Built on research. Backed by real data.
Femora is designed in line with ISO 10993 (biocompatibility), IEC 60601 (electrical safety) principles, and PIPEDA (data privacy).
