The bra that watches over you
PHIBRA is the first garment to combine two complementary technologies — bio-impedance and contact thermography — to detect breast tissue anomalies. Quietly, built into the everyday act of putting on your underwear.

Radiation
Two views of your tissue, one more reliable result
On its own, each signal has its limits. Together, bio-impedance and contact thermography provide a cross-checked reading for greater reliability.
Bio-impedance
Tissue density
A current so weak you can't feel it — yet penetrating enough to reveal changes in density and cellular composition, potential markers of anomalies.
- Multi-frequency
- Measurement inside the breast
Thermography
Metabolic activity
Your body speaks in heat. Abnormal vascular activity — often associated with tumor development — produces detectable thermal signatures; PHIBRA picks them up.
- High-precision contact sensors
- Thermal resolution < 0.1 °C
- Radiation-free, 100% passive
Patent granted in France and pending in Europe and the United States.
Prevention, finally personalized
The app gets to know you, analyzes your risk profile and automatically recommends the follow-up frequency best suited to your situation. The protocol continuously recalibrates.
A protocol tailored to your profile
When you first open the app
You fill in your profile. The algorithm analyzes it and immediately assigns you a personalized frequency protocol, continuously recalibrated.
- Your age and hormonal status
- Your personal and family history of breast cancer
- Any known genetic mutation (BRCA1/2 or other)
- Your most recent medical exams (mammogram, ultrasound, biopsy)
- Your current or past treatments
Calibration
15 min every 2–3 days · for 1 month
The app learns your unique tissue signature. These repeated measurements establish your personal reference profile — the baseline that makes any deviation detectable.
Longitudinal monitoring
15 min per month or per quarter, depending on your profile
The app schedules your sessions, sends you gentle reminders, tracks your measurement curve month after month and can alert you in case of a significant deviation.
AI at the heart of PHIBRA, from design to everyday use
A proprietary algorithm trained on real-world clinical data that turns two streams of raw signals into actionable, personalized information that keeps improving over time.
Digital Twins
In silico clinical validation — digital twins speed up trials before, during and after any human study.
Signal Processing
Embedded signal processing, as close to the measurement as possible.
Predictive Analytics
Population-specific predictive models — refined by age, hormonal status and history.
Patient Monitoring
A longitudinal monitoring interface for the user and her doctor — history, curves, alerts and reports.
Personalized Health
As the user's profile evolves, so does our algorithm — every new data point refines the accuracy of the monitoring.
