Continuous Cuffless Blood Pressure Estimation via ECG-to-PPG Pulse Transit Time
Calculating the precise millisecond interval between the ECG R-peak and the arrival of the arterial blood pulse at the driver's fingertip on the steering wheel.
Arterial Stiffness and Wave Propagation Physics
Applying the Moens-Korteweg arterial elastance equation translates shortening pulse transit times directly into clinical systolic and diastolic blood pressure curves.
- 100% cuffless operation during normal two-handed steering wheel holding.
- Blood pressure accuracy within ±5 mmHg adhering to IEEE 1708 standards.
- Continuous arterial stiffness and pulse wave velocity (PWV) tracking.
- Early detection of hypertensive crisis conditions during stressful traffic.
