Low Cost Electroencephalogram (EEG)

=Problem Definition= In order to better educate high school students about brain function, we are developing an educational, low cost EEG that can be made in classrooms by students. During this year, we are going to determine the least expensive and most easily reproducible way to create and EEG for under $100.

Background
The biggest barrier to introducing high school students to basic neuroscience is the staggering cost of an EEG and the corresponding software. Instead of spending $800 on an EEG device like Emotive, and hundreds of dollars per month on the related software, this new EEG design will deliver open source software and instructions for an easily reproducible hardware design to open neuroscience and basic engineering to all high school students.

Specifications
=Design Considerations= =Project Learning= We have tested several different types of electrodes to use for the EEG. We bought a sample pack of medical grade gold cup electrodes in order to get a base line signal to compare our electrodes to. The main candidates that we have tested are disposable silver cup electrodes, 3D printed electrodes, and DIY electrodes using metal plates. Several of these candidates will have a good chance of being in the final design. Here is an example of the unfiltered signal that we measured from our disposable electrode:
