Designing wearable hardware for breakthrough gamma‑wave neuromodulation therapy
About the Client
Cognito Therapeutics is pioneering a non‑invasive sensory stimulation therapy for Alzheimer’s, using a custom headset (Spectris AD) that delivers 40 Hz light and sound to stimulate gamma wave activity—aiming to preserve cognition, daily function, and brain volume in diagnosed patients
Project Brief
Design a user-centered wearable headset that combines visual and auditory stimulation into a comfortable home-use product. My role encompassed sketching, low-fidelity prototypes, 3D modeling, 3D printing, user testing, design for manufacturing, and an appearance model to align engineering and brand expectations.
Key Challenges
Aligning functional science and wearability The headset needed to house precisely synchronized light emitters and headphones for brain stimulation, and sit comfortably for daily use at home—without feeling medical or industrial in appearance.
Iterative ergonomics with limited tolerance Users needed to wear the device one hour daily. We explored fit, weight distribution, and pressure points using rapid prototypes to refine ergonomics through user testing.
Translating constraints into thoughtful design directions Working from engineering input and known spatial requirements, I designed around internal components like optics, speakers, and thermal elements—ensuring the external form accommodated those needs while maintaining comfort and visual clarity.
Process
Sketching and low‑fi exploration Started with sketches and foam-fit models to test how the headset sat on diverse facial geometries. Rapid iterations helped settle fit and form early.
3D modeling and physical prototyping Built digital models of preliminary design directions. 3D printed prototypes for hands-on testing of fit, comfort, and interface geometry.
Collaborative testing and refinement Conducted user testing sessions to assess comfort and adjust dimensions. Incorporated feedback into next-gen prototypes and CAD iterations.
DFM and appearance modeling Transitioned the validated design into manufacturable form. Developed an appearance model to communicate finishes, textures, and material intent for stakeholders and engineering teams.
Solution
A balanced wearable for therapeutic use at home The resulting headset design compliments the neuroscience inside: delivering synchronized sensory stimulation with a user-centric fit and approachable aesthetic.
A form that supports function and familiarity Despite the technical complexity, the design avoids medical clichés, opting for familiar headset cues instead of clinical associations.
A user‑focused interface that invites compliance Ergonomic refinements encourage consistent wear, while materials and form support ease of use—critical for daily therapeutic adoption.
