A significant MIT investment in advanced manufacturing innovation

These are not your grandmother’s fibers and textiles. These are tomorrow’s functional fabrics — designed and prototyped in Cambridge, Massachusetts, and manufactured across a network of U.S. partners. This is the vision of the new headquarters for the Manufacturing USA institute called Advanced Functional Fabrics of America (AFFOA) that opened Monday at 12 Emily Street, steps away from the MIT campus.
AFFOA headquarters represents a significant MIT investment in advanced manufacturing innovation. This facility includes a Fabric Discovery Center that provides end-to-end prototyping from fiber design to system integration of new textile-based products, and will be used for education and workforce development in the Cambridge and greater Boston community. AFFOA headquarters also includes startup incubation space for companies spun out from MIT and other partners who are innovating advanced fabrics and fibers for applications ranging from apparel and consumer electronics to automotive and medical devices.
MIT was a founding member of the AFFOA team that partnered with the Department of Defense in April 2016 to launch this new institute as a public-private partnership through an independent nonprofit also founded by MIT. AFFOA’s chief executive officer is Yoel Fink. Prior to his current role, Fink led the AFFOA proposal last year as professor of materials science and engineering and director of the Research Laboratory for Electronics at MIT, with his vision to create a “fabric revolution.” That revolution under Fink’s leadership was grounded in new fiber materials and textile manufacturing processes for fabrics that see, hear, sense, communicate, store and convert energy, and monitor health.
From the perspectives of research, education, and entrepreneurship, MIT engagement in AFFOA draws from many strengths. These include the multifunctional drawn fibers developed by Fink and others to include electronic capabilities within fibers that include multiple materials and function as devices. That fiber concept developed at MIT has been applied to key challenges in the defense sector through MIT’s Institute for Soldier Nanotechnology, commercialization through a startup called OmniGuide that is now OmniGuide Surgical for laser surgery devices, and extensions to several new areas including neural probes by Polina Anikeeva, MIT associate professor of materials science and engineering. Beyond these diverse uses of fiber devices, MIT faculty including Greg Rutledge, the Lammot du Pont Professor of Chemical Engineering, have also led innovation in predictive modeling and design of polymer nanofibers, fiber processing and characterization, and self-assembly of woven and nonwoven filters and textiles for diverse applications and industries.

Initial size enables speedy analysis of laparoscopic procedures

Laparoscopy is a surgical technique in which a fiber-optic camera is inserted into a patient’s abdominal cavity to provide a video feed that guides the surgeon through a minimally invasive procedure.
Laparoscopic surgeries can take hours, and the video generated by the camera — the laparoscope — is often recorded. Those recordings contain a wealth of information that could be useful for training both medical providers and computer systems that would aid with surgery, but because reviewing them is so time consuming, they mostly sit idle.
Researchers at MIT and Massachusetts General Hospital hope to change that, with a new system that can efficiently search through hundreds of hours of video for events and visual features that correspond to a few training examples.
In work they presented at the International Conference on Robotics and Automation this month, the researchers trained their system to recognize different stages of an operation, such as biopsy, tissue removal, stapling, and wound cleansing.
But the system could be applied to any analytical question that doctors deem worthwhile. It could, for instance, be trained to predict when particular medical instruments — such as additional staple cartridges — should be prepared for the surgeon’s use, or it could sound an alert if a surgeon encounters rare, aberrant anatomy.
“Surgeons are thrilled by all the features that our work enables,” says Daniela Rus, an Andrew and Erna Viterbi Professor of Electrical Engineering and Computer Science and senior author on the paper. “They are thrilled to have the surgical tapes automatically segmented and indexed, because now those tapes can be used for training. If we want to learn about phase two of a surgery, we know exactly where to go to look for that segment. We don’t have to watch every minute before that. The other thing that is extraordinarily exciting to the surgeons is that in the future, we should be able to monitor the progression of the operation in real-time.”
Joining Rus on the paper are first author Mikhail Volkov, who was a postdoc in Rus’ group when the work was done and is now a quantitative analyst at SMBC Nikko Securities in Tokyo; Guy Rosman, another postdoc in Rus’ group; and Daniel Hashimoto and Ozanan Meireles of Massachusetts General Hospital (MGH).
