近年來生理訊號量測成為了熱門的議題,生理訊號在醫療方面的應用非常廣泛,也成為現在許多大專院校重點開課的項目。其中肌電訊號(EMG)的應用也非常廣泛,但想要觀看肌電訊號時都必須接上示波器才能觀看即時的波形變化,十分不便。本論文主要建構了一套生理訊號無線監控的系統,以肌電訊號為例,創建一個能直接透過手機APP觀看的自己肌肉活動時的波形變化。整體系統架構包括:EMG放大器電路、Arduino與wifi模組以及手機APP所組成。將EMG放大器電路所獲得的肌電類比訊號透過Arduino類比腳位將訊號讀入,再透過wifi模組將訊號傳至雲端資料庫,wifi與手機APP做連結,就可直接透過手機APP無線觀看肌肉活動時,肌電訊號的波形變化,讓學習更方便,更容易推廣。
In recent years, physiological signal measurements has become a hot topic. Biomedical Signal Measurement is very popular in university. However, biomedical signal Measurement requires oscilloscope and power supply. It's very inconvenient. This paper propose a set A Wireless Physiological Signal Monitor System. For Electromyography (EMG) Case. The system includes: EMG signal acquisition、Arduino UNO、Arduino wifi shield and a database in the cloud. We use Arduino to read signal from EMG signal acquisition board. Then the signal data id transmitted to the database in the cloud. The user can use APP through 3G or wifi to connect cloudant database. The APP can get the signals in the cloudant database and draw the waveforms.
