Neural interface technologies stand to revolutionize disease care for patients with intractable neurological conditions and in the future, the human experience. Today, implantable neurostimulation devices have seen widespread adoption in the treatment of motor disorders, OCD, epilepsy, and more. Clinical neurostimulators have few channels and provide simple electrical pulses that are programmed by a doctor in a process that can take months or even years. In this talk I will present custom integrated circuit and microsystems-based advances in neuromodulation technology that combine high channel count neural recording with stimulation in a device that aims to treat a variety of neurological conditions by dynamically delivering and adjusting therapeutic electrical stimulation in response to a patient’s real-time neural state. I will also describe our recent work in shrinking this technology to sub-mm scales using ultrasound for power and communication, enabling safe, sustained use with minimally invasive implantation.
Rikky Muller, PhD is an Assistant Professor of Electrical Engineering and Computer Sciences (EECS) at the University of California, Berkeley where she holds the S.Shankar Sastry Professorship in Emerging Technologies. She is Co-director of the Berkeley Wireless Research Center, a Core Member of the Center for Neural Engineering and Prostheses and an Investigator at the Chan-Zuckerberg Biohub. Dr. Muller received her BS and MS degrees from MIT and her Ph.D. from UC Berkeley all in EECS, and was a McKenzie Fellow and Lecturer of EE at the University of Melbourne in Australia. She was the Co-founder of Cortera Neurotechnologies, Inc. a medical device company founded in 2013 and acquired in 2019. Prior to her PhD she was an IC designer at Analog Devices. Dr. Muller was named one of MIT Technology Review's top 35 global innovators under the age of 35 (TR35), and one of MedTech Boston's top 40 healthcare innovators Under 40. She is the recipient of numerous fellowships and awards, including the National Academy of Engineering Gilbreth Lectureship, the Chan-Zuckerberg Biohub Investigatorship, the Hellman Fellowship, the Keysight Early Career Professorship, the NSF CAREER Award, and is a Distinguished Lecturer of the Solid-State Circuits Society.
