Expansion of In-Ear EEG system

Task: Address the issues presented by introducing motion to Electroencephalography (EEG) acquisition.

EEG is used to record brain activity, which can then be used by medical professionals for different analyses and treatments. We aim to develop a functional in-ear EEG device to collect cognitive data in real time during physical rehabilitation exercises. Working with UC Berkeley EECS and Blue Goji, we are trying to develop a solution and prove feasibility for monitoring brain activity during the usage of Infinity Treadmill and stationary bikes.

My Role: Project Manager/Hardware Design Team Lead

• As project manager, I work with our team members as well as our project advisors to plan the course of the project, including scheduling meetings, setting deliverables, deadlines and managing communication.
• As the hardware design team lead, I am responsible for the development of a headband and in-ear electrode components that maintain impedance levels below 300kΩ, along with my team. 
• I am focused on developing a headband that limits movement of all sensor and electrode components relative to the head of the patient.
• I am focused on the design and development of earpieces that do not move inside the ear to prevent anomalies in the data collection.

Implementation:

• Designed the headbands using SolidWorks moving to 3D printing (FormLabs SLA) for initial prototyping.
• By utilizing Adobe Illustrator and Altium, we were able to develop PCBs for in-ear electrode arrays.
• Design adapter PCBs for the electrode arrays in Eagle.
