The EZG [portable EEG]

Date created
Two main forms of EEGs exist today: a complicated setup of wires in a gel cap that covers the user's entire head, and dry EEGs which sit on the surface of the skin without any gel but that provide a lower signal to noise ratio.  Our EZG provides the practical middle ground between these two existing options. Consisting of two electrodes and an ear clip for ground, the EZG is applied with adhesive to the user's forehead. This versatile and portable setup allows for a wider range of studies than a gel cap, with potential applications for sports and sleep studies. However, the use of adhesive and wet electrodes provides a better and more stable contact than the dry EEGs and is more securely and comfortably attached to the user's head.  The competition on the market is primarily from the full gel cap and dry EEG devices, but the EZG is a cheaper, portable, and more versatile EEG with a better signal to noise ratio than dry EEG devices. This would open up a market with academics wanting ease of use and the ability to perform the wide range of studies that the EZG allows. It would also open up a commercial market for people curious about how their brain acts, with further potential applications for brain computer interfaces.
Undergraduate Engineering students are required to complete a group-based, two-course capstone sequence: ENSC 405W and ENSC 440.  Groups form company structures and create an innovative product that potentially acts as a solution to a real-life problem.  This collection archives the following assignments: proposal, design specifications, requirements specifications, and proof of concept.
