| dc.description.abstract | 本文設計一新式的非接觸生醫感測器，在使用時可以提高量測時的方便性、安全性，不需與皮膚直接接觸，並且能做長時間量測生理訊號。設計依據是依電容性耦合訊號的原理來製作一個非接觸生醫感測器；但生理訊號通常都相當微弱，為了使訊號不受到衰減且能清楚的辨識，而此感測器具有下列優點：
(1) 能濾除直流偏壓且不影響輸入端的阻抗。
(2) 感測器具有高敏感度。
(3) 感測器具有高訊雜比。
(4) 外部屏蔽層，增加抗雜訊的強度。
最後本文將實現所提出之非接觸生理訊號量測系統，並利用本文所設計的新式生理訊號感測器進行實際心電訊號量測，來驗證其正確性，實驗結果證實本論文提出之方法與可行性。

| dc.description.abstract | The purpose of this paper is to design a novel capacitive coupling sensor which provides a convenient, secure, and noncontact measurement for human bio-signal. It is useful for the long-term bio-signal measurement. The method is based on the principle of capacitive coupling to sense bio-signals. However, bio-signals are usually extremely weak. It becomes more difficult to measure bio-signals when using noncontact method. Therefore, this research addresses a new noncontact biomedical sensor having the following four advantages:
(1) Eliminating DC-bias without affecting the input impedance
(2) High sensitivity
(3) High signal-to-noise ratio (SNR)
(4) Reducing interference by making an external shielding
Finally, a non-contact electrocardiogram (ECG) measurement system is designed to verify the feasibility of the proposed capacitive coupling sensor. The presented sensor can be extended to other physiological signal measurement systems.
