Electromagnetics for Biomedical Sciences

On Tuesday, 7th of May 2019, the IEEE NTUA EMB Society and the IEEE NTUA Student Branch in coordination with the Laboratory of Electronic Sensors of the School of Electrical and Computer Engineering, National Technical University of Athens, co-hosted the talk “Electromagnetics for Biomedical Sciences”.

The two-part event took place at the Amphitheater of the NTUA Computer Centre Building.

Main speaker of the event was Evangelos Christoforou, Professor, Director of the Laboratory of Electronic Sensors of the School of Electrical and Computer Engineering NTUA, who presented the applications of electromagnetic fields on medicine.

Electromagnetics find significant applications in engineering and particularly in biomedical engineering. A first example of modern applications of e/m fields is hyperthermia, by means of binging oligopeptide covered magnetic nanoparticles with anti-some over-expressed tumor cells. RF e/m waves heat magnetic particles resulting in hot spot tumor identification. Other examples are related to transcranial magnetic stimulation, trying to monitor and treat brain Diseases. Finally selective magnetic separation can be used for ultra pure polyphenol trapping, as well to heavy ion trapping, indirectly leading to health advances by means of natural pharmaceutical development and water treatment respectively.

The second part of the technical speech was delivered by Spyridon Angelopoulos, PhD candidate in the Division of Communication, Electronic and Information Engineering of ECE-NTUA and included a description of the sensors that can be used for biomedical applications.

Two magnetic sensors were described, regarding their characteristics, their design and construction, as well as the required calibration procedure. Furthermore, an introduction to the use of microcontrollers was presented, which will be followed by a relevant workshop.
