WEEK EIGHT (2)

Bismillahirrahmanirrahim. 

This week I do research about electrodes also. There are two types of electrodes which are active and passive electrode. Active electrode is an electrode with amplifier designed with the electrode attached to it while passive electrode needs amplifier circuit to amplify the signals that the electrode detects. 

For this project, I chose passive electrode which does not have amplifier attached to the electrode. The picture is the passive electrode that I will order with ebay with the help of my friend, Nur Hafiz. I also doing circuit construction for the EOG amplifier. 

Barakallah.
