This $200,000 federal Project Grant awarded by the National Science Foundation (NSF) under the STEM Education (CFDA 47.076) program supports research to advance the design and performance of concentric ring electrodes (CREs), which are noninvasive sensors used for electrophysiological measurements. Specifically, the project aims to 1) directly compare the performance of the optimal tripolar CRE configuration developed at Diné College to commercial CRE configurations using phantom data, and 2) evaluate the optimal versus currently used Laplacian estimation coefficients for CRE prototypes. The project is led by a Diné College STEM faculty member and provides research opportunities for Native American undergraduate and graduate students to enhance the college's STEM instructional and research capacity. The findings from this 2-year project have the potential to optimize the diagnostic value of CREs as medical tools.
