Welcome to Neural interfaces NX-422!
Neural interfaces (NI) are bioelectronic systems that interface the nervous system to digital technologies. This course presents their main building blocks (transducers, instrumentation & communication), and it reviews current and upcoming materials and technological solutions for implantable & wearable NIs.
Teaching team
- Lecturers
- Teaching assistants
Course schedule
The course is articulated around in-class lectures, problem solving sessions and a team project.
In order to maximize learning outcomes and time for your team project, we will follow the attached schedule throughout the semester. Note that time slots for lectures, Problem solving sessions, and Team projects DO vary across the semester.
There will be 2 graded quizzes during the semester, indicated in yellow in the schedule. These will be in-class tests taken on November 1, 2024 and December 6, 2024 during regular lecture times..
Team projects will be shared with the entire class at the end of the semester in the form of a presentation.

Course evaluation
The course evaluation will take place during the semester. There is no written exam in the January 2025 session.
The course grade will come from in-class Quizzes during the semester and team project.
- Graded quizzes (40%)
- Group project (60%)
