隨著穿戴式裝置的發展,個人化的生理訊號量測裝置的需求越來越多,希望提供使用者長時間的量測裝置,本研究是針對量測各種生醫訊號的前端電路為探討,量測時會因外在所形成的雜散電容,共模雜訊與電路上的直流偏壓,這些問題都是會影響擷取訊號的品質好壞,透過補償電容迴路來抵消雜散電容的影響,濾除低頻的直流偏壓,來避免訊號飽和,消除大振幅的共模雜訊,量測脈搏是以壓阻式感測器,擷取手腕動脈上之微小跳動,另外量測心電訊號採用第一導程的黏貼方式,黏貼在左右胸腔上來擷取訊號,最後將電路輸出端,送到嵌入式平台的A/D介面 (Analog-to-digital converter,A/D),經由訊號上的參數計算,以I/O (Input/Output Port)控制類比開關來調整電路參數,獲得脈搏與心電訊號
,並提供給後端系統來分析。


With the development of the wearable devices, the demand for personal physiological signal measurement devices will become more and more popular. We hope to provide users a wearable device with long time measurement capability. In this thesis, a front-end circuit of measurement for various biomedical signal is discussed to cope with the issues of external stray capacitance, common mode noise from environment, and DC offset existing in the circuit. We propose the compensation capacitance mechanism to neutralize the effect of stray capacitance, remove DC offset in low frequency component to avoid the signal saturation, and eliminate common mode noise with feedback approach. Our measurement uses piezo resistive sensor to capture vibration movement of radial artery on the wrist. In addition, we use wet electrode adhesive on the chest in Lead I to get the measurement of ECG signal. Finally, the output signal of the circuit is obtained as an input signal to the A/D interface of embedded platform. The wrist pulse and ECG signals can be obtained with qualified quality for back-end analysis by using an adjustable feedback mechanism.
