Replacement S-Pens: http://amzn.to/2bXeO1g
This video shows whats inside the Galaxy Note 7 S pen. Obviously Samsung isnt going to tell us exactly how the pen functions, but when we open it up and take a look at each of the components, we get a general idea of what the S-pen is capable of.
This video also shows how to replace the little stylus tips that come with the S-Pen. If they wear down, or get lost somehow, it is a very easy replacement.
