Tool/software:
Hi,
We are applying DC BIAS voltage to the human body via a dry electrode.
Due to the unstable nature of the connection it is very sensitive to movement and partial adhesion (such as hair)
The result is a variable DC offset shown in the picked-up signals.
My question is: What methods can be apply to reduce this sensitivity. is there a point in adding another buffer to output the BIAS (maybe higher gain?)?
