本論文開發了一套使用可移動式電極之非直接接觸式心電量測(Indirect-Contact Electrocardiography, IDC-ECG)系統，可以降低移動雜訊與提高訊號品質。此外，我們加入分類標籤(Quality Label, QL)之方法計算訊號品質，並設計實驗針對靜止不動、深呼吸、身體前後傾仰與身體左右轉等4種動作評估其訊號品質。
在靜止不動與深呼吸的實驗中，可移動式電極和固定式電極方式的訊號品質都接近100%，並沒有顯著差異。而身體前後傾仰和身體左右轉的實驗中，可移動式電極相較於固定式電極方式有較高的訊號品質，說明了使用具可移動式電極之非直接接觸式ECG量測系統可使訊號品質顯著提升。

In order to reduce motion artifact and increase signal quality, we used the movable electrode to develop an indirect-contact ECG measurement system in this thesis. Besides, we also created a Quality Label to evaluate the signal quality for four movement situations include sitting, deep breathing, moving forward and backward, and turning left and right.
In sitting and deep breathing experiments, both of the signal qualities for using movable electrode and fixed electrode are closing to 100 percent and have no significant difference. However, the experiments for moving forward and backward as well as the turning left and right show the signal quality of movable electrode is higher than the one of fixed electrode. Therefore, it verifies our system can improve the signal quality significantly when body movement.
