Bionic Prostheses: Sensory Feedback and Control

This lecture discusses advancements in bionic prostheses, focusing on the integration of sensory feedback through peripheral implantable electrodes. The instructor presents various electrode types, including intraneural and epineural electrodes, and their effectiveness in providing sensory feedback. Key studies are highlighted, showcasing the long-term functionality of these implants and their ability to restore sensation. The lecture emphasizes the importance of modulation in sensory feedback, demonstrating how different stimulation parameters can enhance the user experience. The instructor also explores the challenges of assessing sensory feedback through innovative testing methods, such as the cherry-picking task, which illustrates the practical benefits of sensory feedback in prosthetic use. Additionally, the lecture covers the concept of closed-loop control systems, where sensory information is used to adjust the force applied by the prosthesis in real-time. The potential for improving cognitive perception and embodiment in users through advanced neurotechnology is also discussed, highlighting the future of bionic limb integration and rehabilitation.
