Measuring Aortic Blood Ejection Recoil Forces Through Clothing

Embedding cellular ferroelectret film matrices inside the driver seat backrest to record subtle body vibrations generated by heart ventricular contraction.

Engine Vibration Blind Source Separation

Independent Component Analysis (ICA) separates low-frequency cardiac recoil pulses from road surface rumble and powertrain mechanical harmonics.

100% contactless operation requiring zero skin contact or driver effort.
Continuous heart rate and respiratory rate monitoring through thick winter coats.
Sub-millimeter displacement resolution capturing subtle J-wave amplitudes.
Resilient sensor arrays with zero mechanical degradation over 10-year vehicle lifespans.
