Ideally, I wouldn't use only two but many more, that was a suggested approach in order to make signals distinguishable due to the numerous muscle groups in the forearm as well as the fact that they are closely grouped. Also, the sensors are rather pricey in my country thus I am trying to gain individual finger control while minimizing cost.
Putting further thought into this, it may be a better option to have a common ground electrode and then have multiple electrode channels for the different muscle groups in the arm - which avoids using the myoware sensors and then requires the development of boards to process signals and so on.
Thanks for the replies! Really appreciate the input.
