Integrated Systems Neuroegineering Lab @ UCSD - Gert Cauwenberghs
As a Ph.D. student at UCSD, my research centers on developing innovative in-ear EEG systems and exploring the integration of Ag/AgCl electrodes for electrophysiological sensing. I have led extensive investigations into the fabrication methods of dry electrodes, characterizing their performance to optimize bio-signal acquisition. This work, which has been published in Frontiers in Electronics and presented at several IEEE conferences, highlights my commitment to advancing wearable health monitoring systems.

At Nextsense, I contributed to two major in-ear EEG projects. For one clinical product, I designed a test fixture capable of programming the initial shipment of 50 units. I also assisted with 3D printing critical parts and assembling units to meet a tight shipping deadline. The test fixture was instrumental in reducing assembly time and ensuring the timely delivery of the devices.
For the second project, still in its beta phase, I spearheaded the development of several innovative test fixtures designed to assess electrode performance and diagnose device issues. One of the key fixtures, which I designed under a tight deadline, was deployed internationally to support testing and troubleshooting of the analog front end of the prototypes during assembly. Additionally, I engineered an intuitive impedance testing device that greatly enhanced the speed and reliability of electrode quality assessments. To further elevate the testing process, I introduced a PBS-based EIS electrode testing bath, providing a standardized, skin-independent method for evaluating electrode characteristics. These solutions, paired with clear SOPs and technician training, streamlined operations and significantly accelerated the testing and fabrication workflows.

During my time at the Army Research Laboratory, I focused on advancing the performance and fabrication techniques of Ag/AgCl electrodes for in-ear EEG applications. Working both on-site and remotely during the COVID-19 pandemic, I explored various methods to optimize electrode performance, ensuring the electrodes provided reliable, high-quality bio-signal acquisition.
A crucial aspect of my research was the development of custom-fitted earpieces, uniquely tailored to each individual’s ear. The combination of well-designed, custom earpieces and high-quality electrode fabrication significantly improved signal quality, electrode contact, and spatial resolution of the limit area of the ear. This synergy is essential for overcoming the challenges posed by the complex and unique geometry of the ear.
