着衣越しの大動脈血液駆出反跳力の非接触計測

心室収縮によって生じる微細な身体振動を捉えるため、ドライバーズシートのバックレスト内部に強誘電性エレクトレットフィルムマトリックスを配置。

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.
