DESAIN TUTUP KEPALA DENGAN PEMANFAATAN LOGAM Cu SEBAGAI APLIKASI UNTUK MENENTUKAN LOKASI SINYAL OTAK SAAT BERAKTIFITAS

Electroencephalography (EEG) is the recording of electrical activity along the scalp produced by the firing of neurons within the brain. Signals were taken by attaching electrodes on the surface of the head. But the installation of electrodes sometime will cause inconvenience to the subject and takes a long time. To solve that problem, will be made easy to operate EEG module, and head cap with Cu or AgCl electrode holder which positioned according to the 10 or 20 electrode placement system. It aims to make the recording process easier and minimize the electrode placement errors. Based on the result of twenty electrode placement test, obtained the recorded signals which approached the expected form for alpha is 50%, for beta is 60% and teta is 10%.
