39475 - Eletronic Bioengineering Applied To Prosthesis

Learning outcomes

After completing this module the student will have basic knowledge of the physical principles and technologies used in sensors and in particular the sensors used in the prosthetic including processing and filtering of sensor data. The student will have knowledge of the actuators and transducers present in prosthetic systems and the basics of telecommunications in order to understand how to connect between PC and Prosthetics.
