Lecture
This lecture covers the challenges of data transmission in implantable devices, focusing on cochlear and retinal implants, and the complexities of sensory substitution. The instructor explains the need for efficient wireless data transfer links and the asymmetrical requirements for sensory substitution and brain-computer interfaces. Various techniques such as impulse radio and pulse harmonic modulation are discussed for achieving high data rates without carrier signals. The lecture also delves into the design considerations for inductive links, emphasizing the importance of measuring bit error rates for robust data transfer. Finally, the applications of wireless power and data transfer in medical devices, particularly for spinal cord injuries, are explored.
