Migraine
Catch migraine prodrome from hydration, autonomic, and hormonal signal in the room people already use. Three times the prevalence in women; ~78B/yr in US lost productivity.
Specific gravity
Urine concentration. Direct hydration signal.
pH (urine)
Urine acidity. Drift signals diet, hydration, infection risk, and renal function.
Urinary cortisol
Stress and HPA-axis signal.
Urinary hormones
LH, FSH, estrogen metabolites, progesterone metabolites for cycle and fertility.
Heart-rate variability
Beat-to-beat variation. Autonomic balance, recovery, stress, and overtraining signal.
Heart rate
Beats per minute. Cardiovascular and recovery signal.
Voiding frequency
Visit count and nocturia events. Sleep, prostate, and metabolic signal.
Pallor & jaundice
Skin tone shifts indicating anaemia, liver, or perfusion changes.
Skin temperature
Surface temperature trend. Cycle phase, infection, and circulation signal.
Breath VOCs
Volatile organic compounds in exhaled air. Metabolic state and gut signal.
Urinalysis test strip
10-parameter reagent strip read at the seat. Captures pH, nitrites, leukocytes, glucose, blood, protein, ketones, urobilinogen, bilirubin, and specific gravity from each void.
Urine spectroscopy (optical / SERS)
Non-contact optical analysis of urine in the bowl or stream. Uses vis-NIR absorbance, fluorescence, and surface-enhanced Raman spectroscopy (SERS) to fingerprint analytes without consumables. Calibrates against the same biochemistry strips read by urinalysis.
Urine immunoassay
Lateral-flow and microfluidic assays measuring hormones, drug metabolites, and infection-specific biomarkers from urine.
ECG electrodes
Contact electrodes integrated into the seat for short-arm and short-leg ECG. Captures rhythm, conduction, and waveform morphology each sit.
PPG / optical sensor
Photoplethysmography optical sensors at the seat and handrail contact points. Captures heart rate, HRV, and SpO₂ from blood-volume pulse.
Mirror camera
Low-resolution facial and torso imaging behind the mirror with on-device inference. Reads heart rate, respiration, and SpO₂ via remote photoplethysmography (rPPG); also captures skin tone, posture, and gesture. Raw frames never leave the room; only features.
Microphone array
Directional microphones in the bowl or rim capturing acoustic signatures of urinary flow, voiding patterns, and breath/cough sounds.
Load cell array
Strain-gauge load cells in the floor mat and seat for weight, weight distribution, balance, gait timing, and sit-to-stand dynamics.
Thermal sensor
Long-wave infrared array reading skin temperature and circulation patterns. Useful for cycle phase, fever, and peripheral perfusion.
Breath VOC sensor
Metal-oxide and electrochemical arrays for volatile organic compounds in exhaled breath. Useful for ketones, gut metabolites, and infection signatures.

How might we surface migraine prodrome 6-24 hours before onset from passive hydration, HRV, and pallor signal?
- 02
How might we tie menstrual-cycle hormone signal to migraine pattern without an extra app?

How might we route bathroom-derived migraine signal into employer wellbeing programs without surveillance?
