W6: Analog techniques for Neural Interfaces


14:00 - 17:30

room 6


Carolina Mora Lopez, Pieter Harpe


Implanted electronics performing neural recording or stimulation in the brain or other parts of the nervous system are becoming increasingly important. This workshop will give insight in the limitations stemming from the application and the major technical challenges to be solved. First, an overview is given of the key components and the overall system integration aspects, followed by a review of the main technical hurdles. Next, state-of-the-art solutions for wireless power transfer for implants are presented. After that, the workshop will look at circuits and systems for neural & biopotential recording, neurostimulation and neuromodulation.
