Bioelectricity

Bioelectricity. Instructor: Prof. Mainak Das, Department of Biological Sciences and Bioengineering, IIT Kanpur. The course aims at helping the students to think and appreciate the myriad of bioelectrical phenomenon in the nature. This includes the bioelectrical signals in animal, plants and in several bio-materials. These are not only important in physiological functioning of the system but offers enormous inspiration to develop novel sensors, actuators, energy-harvesting platforms for sustainable developments. The thrust of the course will be to highlight "how we can record the electrical signals from wide range of specimens, analyze them and thinking in an innovative manner to use them for energy harvesting and other bioengineering applications. The final goal of the course is to empower students to use their conceptual understanding to develop sustainable technologies. (from nptel.ac.in)
