Athletic recovery & hydration

• Heart-rate variability

  Beat-to-beat variation. Autonomic balance, recovery, stress, and overtraining signal.

• Heart rate

  Beats per minute. Cardiovascular and recovery signal.

• Specific gravity

  Urine concentration. Direct hydration signal.

• pH (urine)

  Urine acidity. Drift signals diet, hydration, infection risk, and renal function.

• 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.

• 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.

1. 01

   How might we turn the bathroom into a recovery dashboard for serious athletes?

2. 02

   How might we read hydration and electrolyte balance continuously across the day?

3. 03

   How might we surface overtraining from urinary and behavioural signal before injury?
