About the Distinguished Lecturer
Dr. Hermano Igo Krebs has been a Principal Research Scientist at MIT’s Mechanical Engineering Department and the Director of The77Lab (http://the77lab.mit.edu/). He also holds an affiliate position as an Adjunct Professor at University of Maryland School of Medicine, Department of Neurology, and as a Visiting Professor at Fujita Health University, Department of Physical Medicine and Rehabilitation (Japan), at Osaka University, Mechanical Science and Bioengineering Department (Japan), and at Loughborough University, Rehabilitation Robotics of The Wolfson School of Mechanical, Electrical, and Manufacturing Engineering (UK).
He is a Fellow of the IEEE and was nominated by two of IEEE societies: IEEE-EMBS (Engineering in Medicine & Biology Society) and IEEE-RAS (Robotics and Automation Society) to this distinguished engineering status “for contributions to rehabilitation robotics and the understanding of neuro-rehabilitation.” He received “The 2009 Isabelle and Leonard H. Goldenson Technology and Rehabilitation Award,” from the Cerebral Palsy International Research Foundation (CPIRF) and the 2015 IEEE-RAS INABA Technical Award for Innovation leading to Production “for contributions to medical technology innovation and translation into commercial applications for Rehabilitation Robotics.” He was selected as a 2021 IEEE-EMBS Distinguished Lecture.
Entrepreneurial Experience
He was one of the founders, member of the Board of Directors, and the Chairman of the Board of Directors of Interactive Motion Technologies from 1998 to 2016. He successfully sold it to Bionik Laboratories, a publicly traded company, where he served as its Chief Science Officer and as a member of the Board of Directors until July 2017. He later founded 4Motion Robotics to revolutionize the way rehabilitation medicine is practiced today by applying robotics and information technology to assist, enhance, and quantify rehabilitation.

Lecture Topic: Starting a Venture Company
Abstract:
“Imagine being present at the birth of a new industry. . . trends are now starting to converge and I can envision a future in which robotics devices will become a nearly ubiquitous part of our day-to-day lives. Technologies such as distributed computing, voice and visual recognition, and wireless broadband connectively will open the door to a new generation of autonomous devices that enable computers to perform tasks in the physical world on our behalf. We may be on the verge of a new era, when the PC will get up off the desktop and allow us to see, hear, touch and manipulate objects in places where we are not
physically present.” – Bill GatesDisruptive technology is a term coined to characterize an innovation that disrupts an existing market or way of doing things and creates a new value network. The concept was first described at Harvard Business School by Clayton M. Christensen, who described the concept in 1996 as: “Generally, disruptive innovations were technologically straightforward, consisting of off-the-shelf components put together in a product architecture that was often simpler than prior approaches. They offered less of what customers in established markets wanted and so could rarely be initially employed there. They offered a different package of attributes valued only in emerging markets remote from, and unimportant to, the mainstream.”;
Eventually with improvement, borrowing from Malcolm Gladwell, the moment of critical mass, the threshold, the boiling point is reached and the old practices and existing value network is abandoned in favor of the new one.
Here I will discuss my experience as an entrepreneur and whether rehabilitation robotics has achieved its “tipping point”.

Spring 2021: Dr. Chestek of University of Michigan
About the Distinguished Lecturer
Dr. Cynthia A. Chestek, from the University of Michigan, Ann Arbor. Dr. Chestek received her B.S. and M.S. degrees in electrical engineering from Case Western Reserve University in 2005 and a Ph.D. degree in electrical engineering from Stanford University in 2010. She was a postdoctoral fellow at the Stanford Department of Neurosurgery with the Braingate 2 clinical trial. She is now an associate professor of Biomedical Engineering at the University of Michigan, Ann Arbor, MI, where she joined the faculty in 2012. She runs the Cortical Neural Prosthetics Lab, which focuses on brain and nerve control of finger movements as well as high-density carbon fiber electrode arrays. She is the author of 53 full-length scientific articles. Her research interests include high-density interfaces to the nervous system for the control of multiple degrees of freedom hand and finger movements.

Title: “Neural Interfaces for Controlling Finger Movements” View a recording here
Abstract
Brain machine interfaces or neural prosthetics have the potential to restore movement to people with paralysis or amputation, bridging gaps in the nervous system with an artificial device. Microelectrode arrays can record from hundreds of individual neurons in the motor cortex, and machine learning can be used to generate useful control signals from this neural activity.
Performance can already surpass the current state of the art in assistive technology in terms of controlling the endpoint of computer cursors or prosthetic hands. The natural next step in this progression is to control more complex movements at the level of individual fingers. Our lab has approached this problem in three different ways.
For people with upper limb amputation, we acquire signals from individual peripheral nerve branches using small muscle grafts to amplify the signal. After a successful study in animals, human study participants have recently been able to control individual fingers online using indwelling EMG electrodes within these grafts.
For spinal cord injury, where no peripheral signals are available, we implant Utah arrays into finger areas of the motor cortex, and have successfully decoded flexion and extension in multiple fingers. Decoding “spiking band” activity at much lower sampling rates, we recently showed that power consumption of an implantable device could be reduced by an order of magnitude compared to existing broadband approaches, and fit within the specification of existing systems for upper limb functional electrical stimulation.
Finally, finger control is ultimately limited by the number of independent electrodes that can be placed within the cortex or the nerves, and this is in turn limited by the extent of glial scarring surrounding an electrode. Therefore, we developed an electrode array based on 8 um carbon fibers, no bigger than the neurons themselves to enable chronic recording of single units with minimal scarring.
The long- term goal of this work is to make neural interfaces for the restoration of hand movement a clinical reality for everyone who has lost the use of their hands.

About the Distinguished Lecturer
Professor David B. Grayden is Clifford Chair of Neural Engineering in the Department of Biomedical Engineering, Melbourne School of Engineering and the Graeme Clark Institute for Biomedical Engineering.
Dr. Grayden’s main research interests are in understanding how the brain processes information, how best to present information to the brain using medical bionics, such as the bionic ear and bionic eye, and how to record information from the brain, such as for brain-machine interfaces.
He is also conducting research in epileptic seizure prediction and electrical stimulation to prevent or stop epileptic seizures, and electrical stimulation of the vagus nerve to control inflammatory bowel disease.
Together with the Melbourne Business School, he teaches BioDesign Innovation, an immersive course in how to innovate in Medical Technologies for Master of Engineering and Master of Business Administration students.

Title: “Brain Recording and Stimulation with the Stentrode”
Abstract
Neural interfaces have the potential to restore lost motor or sensory function and alleviate neurological symptoms for people with spinal cord injury, motor neuron disease, limb amputation, Parkinson’s disease, epilepsy and potentially other conditions. However, to provide the best level of performance, these systems have so far required direct implantation of electrodes into the brain via open craniotomy.
We have developed a stent-electrode array, called the “Stentrode”, that is placed within a blood vessel in the brain where they can chronically record and stimulate brain activity. This presentation will describe the development of the Stentrode from idea to first-in-human trials.

Title: “Non-Pharmaceutical Treatment of Dementia”
Abstract
Memory and cognitive declines are associated with normal brain aging but are also precursors to dementia, in particular Alzheimer’s disease. While currently there is no cure or “vaccine” against dementia, based on brain’s plasticity, there are hopes to delay the onset or to slow the progression of disease.
Alzheimer’s disease is multi-facet condition; thus, the key to its management is in multi-disciplinary approaches. The clinical treatment of Alzheimer’s is basically a family of cholinesterase inhibitors like Aricept that the majority have a very low response rate. In this talk, I will review and discuss non-pharmaceutical treatments such as repetitive transcranial magnetic stimulation (rTMS) and transcranial alternative current stimulation (tACS) with and without Cognitive Exercises. Some pilot results of our current clinical trials will be presented.
