Electroencephalograms or EEGs are useful tools for monitoring brain activity, but they can also be expensive. The goal of this project is to create a wireless, EEG sensor at a lower than typical cost. By using a Teraohm-Input-Impedance FET Buffer, the cost and quality of the electrodes used can be decreased while still achieving sufficient accuracy due to a superior signal to noise ratio. Our system accurately amplifies and displays brain waves with a bandwidth of .5 to 40 Hz while retaining signal quality and minimizing noise within the system. Benefits of this system include a high level of portability, low cost, and simplicity of use.
