OVERVIEW

"Bioelectronics" is a basic course to electronic devices and biophysical systems. Bioelectronics is a theoretical course and aims to provide the student knowledge and operational skills related to solid state physics and biophysics, with particular insights into the theoretical-modeling aspects of electronic devices and biological membranes. From a methodological point of view, the course seeks to highlight the common language between the study of natural and artificial systems through the unifying language of mathematics.
