Implantable Devices for Bioelectronic Medicine: Designing Miniature Devices and Local Wireless Platforms for the Future of Therapeutics
Multimodal implantable medical devices (IMDs) can enable neuromodulation-based therapies for diseases and conditions that currently cannot be treated adequately with medication alone, thus potentially improve the quality of life for people worldwide. It is well understood that IMDs with minimum invasiveness are highly desired. This can be achieved by developing miniature, feature-rich IMDs with novel circuit topologies and system architectures. In this talk, I will present novel and complete biomedical systems I have designed for behavioral neuroscience studies on freely behaving rodents. Spanning from the development of different types of IMDs to wireless power transmission strategies and to wireless data acquisition interfaces, I will discuss the design of each fundamental component, and how these components come together to form the complete system. In particular, I will present analog front-end designs for sensing and stimulation, followed by inductive link designs for omnidirectional wireless power transmission, and a wireless data receiver design for enabling large wireless coverage and eliminating RF blind spots. Finally, I will conclude this talk with future research directions to address remaining challenges for translating the IMD technologies to clinical practice. I will focus on developing miniature implants with multiple functionalities and designing local wireless platforms for power transmission and networking of implants.
