Hi,

I have been studying the development of a 3D printed myo-electric prosthesis.
These EEG sensors are EMG capting the forehead muscle.
A good EMG sensor cost 350€, a low cost one 50€ but there is no potentiometer to adjust the sensibility, and it suffers much because of elecrostatic interferences.
If you have more accurate information about these sensors, please let me know.

Best regards,

g.
