Interest in Cyton pre-amplification

We are a team of electrical engineering students
working on a way to amplify EEG electrode signals coming into the Cyton board.
We are using an amplification circuit that would be connected in between the
electrodes and the input pins of the Cyton board. The circuit is designed for
up to 8 inputs using an SRB pin as reference. The PCB will plug directly into
the Cyton board and use the existing ±2.5V pins for power.

Here is a schematic of the PCB layout and one of the
channel amplifiers:

These pictures show a comparison of some preliminary
results using function generators to simulate a two sinusoidal EEG signal
buried in white noise. The first does not use our pre-amplifier and the second
one does.

We are looking to gauge interest in this kind of
setup.
