EEG for Human and Rat

=Problem Definition= The goal of the project is to create a low cost electroencephalogram device (EEG) that collects accurate data, and is easy for high school students to use and have access to. The secondary goal for this project is to create another EEG device for rats, that is to be used as a non-invasive testing method.

Background
The first part of this project stems from the need for more affordable resources for high school student. The average cost for an EEG is upwards of $800, which is much too expensive to be utilizes in most high schools. This is where we come in, we are trying to create an EEG device that can be made for under $100 that is able to collect accurate data, and aide the learning of students. The second part of this project comes from there not being a way to read a rat's brain waves without being incredibly invasive to the rat as well as endangering its life. We are out to create an EEG that is small enough and accurate enough to read a rat's brain waves without being overly invasive.

Deliverables
For this project, our final deliverables will be slightly different based on the species it is meant for. For the human edition of the EEG, we are hoping for a fully functional, reliable, brain wave measuring device that is under $100. For the rat edition of this project, we are expecting to finish with a fully functioning EEG device, that is non-invasive, and can be used to measure the brain waves of rats.

Specifications
Human Edition: This version of the EEG has a few requirements that need to be met. This will be a very lightweight device that is more portable than most. It will also be made from neoprene and be flexible enough to fit almost any head. This will be nice for high schoolers to use because it is very universal. It also needs to be under $100 to make in order for it to be affordable for high schools to have access to. Rat Edition: The rat version of this project has a few different requirements. The main one is for the device to be non-invasive. As of now, there really are not any EEG devices out there that work for a rat brain. Most procedures involve implanting the EEG itself into the rats brain, which requires surgery and is dangerous for the rat. For this device, we will be able to simply place it on top of the rats head, and it will read the waves.

=Design Considerations= For this EEG, we changed up the design from the previous years. They have all gone with a rigid 3D printed design, but we are trying to find something more flexible. For this we decided to use neoprene and make it more of a "wig-cap" design to ensure a stronger connection. The neoprene reduces the amount of noise to to lack of shifting around, and seems to be the best design. For the rat version of this, the device will be significantly smaller than the human one. We will instead use only four electrodes, and make the process as non-invasive as possible.

Prototypes
Throughout the process of trying to come up with a new design for this project, we had a few different prototypes.
