Hello,

I want to take your opinion about a serious problem I am facing through using the EMOTIV EPOC+ machine. 

The quality of the signals is becoming poor (0 to 25%) when I am trying to apply more than one experiment (experiment time : 25min) related to my thesis project, I tried many ways to maintain the quality of signals from one experiment to another but all failed.

I tried :

1-) Using saline solution in the same way as mentioned in the EMOTIV website.
2-) Removing all electrical wires and electrical devices away from the dongle.
3-) Asking the participants to sit down on a comfortable chair and place their legs on a chair facing them in order to ensure their fixed position.
4-) Achieving the perfect contact quality between electrodes and the student's sculp (100%) 
5-) There were no hair below the frontal electrodes.

Any suggestions could help us continue the experimental part of our thesis project successfully.

I look forward to hearing from you soon,

Best regards,
Hadi Ammar
