Evaluation of CNT/MOSFET Based Active Electrode with ECG, EMG, and EEG Signals

Öz

In this study, the electrical circuit equivalents of the previously designed novel CNT/MOSFET based active electrode and commonly used wet electrode are simulated by applying different biopotentials. Responses of the electrode models are compared within the certain skin surface circumstances. Fourier transforms and total harmonic distortion calculations of obtained biopotentials are examined to assess the electrodes. The simulation results demonstrate that the CNT / MOSFET based electrode predominates the wet electrode and can measure biopotentials with high quality.

KNT/MOSFET Tabanlı Aktif Elektrotun EKG, EMG, EEG İşaretleri ile Değerlendirilmesi

Öz

Bu çalışmada, önceden tasarlanmış olan özgün KNT/MOSFET tabanlı aktif elektrotun ve yaygın olarak kullanılan ıslak elektrotun elektrik devresi eşdeğerlerine, farklı biyopotansiyeller uygulanarak benzetimleri gerçekleştirilmiştir. Elektrotların giriş sinyallerine verdiği yanıtlar, belirli cilt yüzeyi koşullarında karşılaştırılmıştır. Elektrotları değerlendirmek için elde edilen biyopotansiyellerin Fourier dönüşümleri ve toplam harmonik bozulmaları incelenmiştir. Simülasyon sonuçları, KNT/MOSFET tabanlı elektrotun ıslak elektrottan daha iyi sonuçlar verdiğini ve biyopotansiyelleri yüksek kalitede ölçebileceğini göstermektedir.
