EEG DATA COLLECTION HEADSET

Description

For my capstone mechanical engineering project, a team of 2 other mechanical engineers and I created a headset to collect EEG data in unison with VR/AR goggles.

My Role

  • Owned the mechanical design of the electrode straps

  • Managed the project timeline via Gantt Chart

  • Determined the engineering specifications for the product

  • Created open source instructions for replicating the product

The Problem

The Mitsubishi Electric Research Laboratories (MERL) are interested in using an EEG headset device in unison with VR goggles, but the existing electrode cap is rigid, clunky, not adjustable, and potentially damaging to the VR goggles. Thus, the research team needs better mechanical hardware for sensing and collecting biosignals that can be flexibly integrated alongside VR headsets.

Over the course of the semester, my partners and I designed and fabricated a physical headset for OpenBCI comb EEG sensors that can collect data for a range of head sizes. The headset fits with any type of AR/VR goggles and allows users to wear both the goggles and headset at once during data collection. After we completed our design, we published our CAD files, step-by-step instructions for assembly, and other materials needed to recreate the headset on the OpenBCI community forum so that other users of OpenBCI technology can recreate it for their own data collection.
