This past week, I got the preliminary hardware up and running, including the MyoWare Muscle Sensor System and the sandbox code for it. I tested a single electrode to verify that our chosen hardware would work before we moved forward with it. With this, we now know that our approach is valid. 

Here’s some pictures of the process. This was tested on the right brachioradialis muscle, with the reference electrode put on the humeral medial epicondyle. 

  

I also put together the Bill of Materials and filled out the form to get our parts ordered. At the end of the week the parts arrived, and I have been working on a hierarchical referencing scheme to conserve power among the electrodes so they can share a common ground. I have also been soldering together the wires to the electrodes to make our system more robust and portable. 

Next week, I’ll start the data collection experiment along with Kayla, so we can have preliminary data to play with and develop our classifiers on the signal processing side.
