近年有許多生理信號穿戴式裝置，但因價錢在市場上偏高，所以本論文打造低成本且縮小化的生理信號擷取整合系統電路，本系統包含：數位式低壓差穩壓器(Digital Low-dropout regulator, D-LDO)、肌電(Electromyography, EMG)、心電(Electrocardiography, ECG)、腦電(Electroencephalography, EEG)讀取電路、類比濾波器、核心控制與擷取顯示，由D-LDO負責提供生理訊號擷取電路穩定的電壓，再將擷取到的訊號經透過Micro Control Unit (MCU)內的數位濾波器演算法處理出更清晰的訊號，最後由連接的藍牙4.0傳輸即時的生理資料於手機App上。 In recent years, there are many body signal wearable devices, but the price is high in the market. This paper proposed a low-cost and minify Biomedical Sensing Device (BSD). The system includes: Digital Low-Dropout Regulator (D-LDO), electromyography (EMG), electrocardiography (ECG), electroencephalography (EGG) circuit, digital filtering , MCU control and display. The D-LDO is responsible for providing the BSD of the stable voltage, and then the captured signal is processed through the digital filter algorithm to processed a clearer signal in the Micro Control Unit (MCU). Finally the connected Bluetooth 4.0 Transfer instant physiological data to the Android App.
