전도성 가죽 표면을 통한 마이크로볼트 단위 심장 전위의 정밀 획득
스티어링 가죽 아래에 초고입력 임피던스(>100 GΩ) 계측 증폭기를 갖춘 전도성 폴리머 전극을 내장하여 건식 접촉 저항 극복.
Motion Artifact and Baseline Wander Cancellation
Wavelet transform filtering strips mechanical hand-rubbing noise and in-vehicle 50/60 Hz electromagnetic interference in real time, delivering a pristine P-Q-R-S-T wave.
- Lead-I clinical ECG acquisition directly through driver palm contact.
- Input impedance exceeding 100 Gigaohms with active guarding.
- Real-time baseline wander cancellation using stationary wavelet transforms.
- Full compliance with IEC 60601-2-47 ambulatory ECG diagnostic standards.
