I am back with another update on my "Wearable Sudden Impact and Health Monitor" project.
In my previous update I showed how I improved my Android app by adding a graph that will display the real time ECG measurement. That time the graph was functional but the hardware and firmware for capturing the ECG was not done yet.
So I started to experiment with the Analog Devices AD8232 evaluation board, which I found extremely easy to setup and use. In only a few minutes I had a ECG signal displayed on the Tektronix TBS 1202B-EDU oscilloscope. Here is a picture of this experiment.
The blue wires connect to the electrodes placed on my chest. Based on this experiment I selected the location of the electrodes. My next step was to capture the ECG and send it to the Android app running on my cell phone. I spent some time getting this to work, but I am happy to see it functional now. Here is a picture of the ECG displayed on my cell phone.
My next step will be to write a function that measures the heart rate from the ECG signal.
This is where I got so far with my wearable impact and health monitor system. I will come back with other updates as I get more work done.
Best Wishes,
Cosmin
