Bioelectronics and Biosensors
Last Updated: 2026-02-05 15:48:31
Abstract
The course introduces bioelectricity and the sensing concepts that enable obtaining information about neurons and their networks. The sources of electrical fields and currents in the context of biological systems are discussed. The fundamental concepts and challenges of measuring bioelectronic signals and the basic concepts to record optogenetically modified organisms are introduced.
Objective
During this course the students will: - learn the basic concepts of bioelectronics - be able to solve typical problems in bioelectronics - learn about the remaining challenges in this field
