A new paper has been published recently in the peer-reviewed journal Sensors (impact factor 3.576; JCR Q1 rank in Instruments & Instrumentation) by the head of the Mathematics for Engineering Applications laboratory (MEA lab) Dr. Oleksandr Makeyev and his collaborators from the Universitat Politècnica de València in Spain. In this paper they used computer simulations to test the optimal design of the concentric ring electrode, which was recently patented (patent number 11,045,132) by the College. Not only did the obtained results suggest that this optimal electrode design indeed maximizes the accuracy of the signal recorded via the electrode, but it also may offer improved sensitivity and spatial resolution which basically means that out of numerous electric sources in the human body, the signal recorded via the electrode will mostly correspond to sources that are the closest to it. These results confirm the potential of the electrode design for noninvasive electrophysiological measurement applications where signals from brain, heart, muscles, etc are recorded by clinicians to diagnose disorders and is likely to increase the value of the College’s patent. Title of the paper is “Comprehensive Optimization of the Tripolar Concentric Ring Electrode Based on Its Finite Dimensions Model and Confirmed by Finite Element Method Modeling”
The MEA lab is located on the second floor of the Kinyaa'áanii Charlie Benally Library (LIB-207) at Tsaile Campus and will participate along Diné College Libraries in the upcoming Trunk or Treat event later this week. MEA lab is externally funded by the National Science Foundation and provides undergraduate students with the cutting edge research experience via paid research assistantships.
