Nowadays, health care at home becomes more and more important, there are also some product which can measure the ECG, EMG with wearable devices. However, these devices are not so accurate for diagnosis because of the low sample rate and less channel on body. In this project, we design a wearable system with 8-channels AFE and use Wi-Fi module to transfer the data to cloud so that we can measure the ECG or EMG more accurate at home, almost at the same sample rate and channels at the hospital. And then the cloud is built for received the data and a real-time display can help doctor monitor the patients’ condition remotely. template is essential with some standard steps.
