18-819E: Special Topics in Applies Physics: Neural Technology, Sensing, and Stimulation

Units: 12

Neural Technology, Sensing, and Stimulation

This course gives engineering insight into the operation of excitable cells, as well as circuitry for sensing and stimulation nerves. Initial background topics include diffusion, osmosis, drift, and mediated transport, culminating in the Nernst equation of cell potential. We will then explore models of the nerve, including electrical circuit models and the Hodgkin-Huxley mathematical model. Finally, we will explore aspects of inducing a nerve to fire artificially, and cover circuit topologies for sensing action potentials and for stimulating nerves. If time allows, we will discuss other aspects of medical device design. Students will complete a neural stimulator or sensor design project.

Prerequisites: 18-220 or equivalent, or an understanding of basic circuits, differential equations, and electricity and magnetism. Some review of circuit theory will be provided for those who need it.
