CHF (congestive heart failure)
Catch CHF decompensation at home from daily heart, weight, and fluid signal, before the ED visit.
Heart rate
Beats per minute. Cardiovascular and recovery signal.
Heart-rate variability
Beat-to-beat variation. Autonomic balance, recovery, stress, and overtraining signal.
ECG rhythm
P, QRS, T waveforms. Arrhythmia, conduction, and ischaemia screening.
Weight & body comp
Daily mass, fluid retention proxy, and trend signal for CHF, metabolic, and recovery.
SpO₂
Peripheral oxygen saturation. Sleep apnea and cardiopulmonary signal.
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.
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.
- 01
How might we catch CHF decompensation 7-14 days before the emergency visit?
- 02
How might we make daily ECG, HRV, and weight legible to a heart-failure clinic?
- 03
How might we route bathroom-derived signal into the heart-failure care plan without an app?
