Title: Silicon technologies and ASICs for high-density neural interfaces and organ-on-chip
Abstract: The human central and peripheral nervous systems are very intricate and intriguing systems. Cell and brain interfacing has gained a lot of interest in recent years. Thanks to advancements in technology scaling, current state-of-the-art systems are able to record the electrical activity down to single neuron resolution from several hundreds of recording sites at the same time.
This is a critical tool for neuroscientists to help understand how our brain operates and stands to revolutionize treatment of neurological disorders. Imec has been developing high-density neural silicon probes for a few years now. This talk will discuss the basic background of this field and then dive deeper into high-density neural recording probes as well as silicon platforms for interfacing with in-vitro cell cultures which is relevant for organ-on-chip applications.
Bio: Nick Van Helleputte received the MS degree in electrical engineering in 2004 from the Katholieke Universiteit Leuven, Belgium. He received his Ph.D. degree from the same institute in 2009 (MICAS research group). His PhD research focused on low-power ultra-wide-band analog front-end receivers for ranging applications. He joined imec in 2009
as an Analog R&D Design Engineer. He is currently R&D manager of the Connected Health Solutions group. His research focus is on ultra-low-power circuits for biomedical applications. He has been involved in analog and mixed-signal ASIC design for wearable and implantable healthcare applications. Dr. Van Helleputte has developed ultra-low-power custom ICs for multi-modal vital signs sensing. His research focused on complete system-on-chip solutions covering all aspects including analog amplification and filtering, analog-to-digital conversion, digital signal and processing power management. He also worked on neural interfaces in the form of active high-density neural probes for the central and peripheral nervous system. In addition to IC design, his research group has a strong focus on highly miniaturized and ultra-low-power systems based on both COTS as well as their custom ASICs. His research collaborations included early pathway research (TRL 1-5) as well as bilateral collaborations with industrial partners towards novel product developments (TRL 5-8). Nick is an IEEE and SSCS member (SSCS Distinguished Lecturer ’17-‘18) and served on the technical program committee of VLSI circuits symposium and ISSCC.
