Living Soft Robots

Overview

Light-guided Biohybrid Robotic Ray

Primary Investigator: Sung-Jin Park, Ph.D

The Disease Biophysics Group at Harvard, led by Kevin Kit Parker, created a tissue-engineered soft-robotic ray that swims using wave-like fin motions, and turns according to externally applied light cues.

Caltech and Harvard Synthetic Jelly Fish Explained

Primary Investigator: Janna Nawroth, Ph.D

Learning from the Jellyfish: Squishy pumps for biomedical and engineering applications
Most people know jellyfish as a painful nuisance, a beautiful aquarium exhibit or–less commonly–in the form of a marinated snack. Now a team of researchers at Caltech and Harvard University have taken yet another perspective on this simple invertebrate; for them, it constitutes nature’s prototype of a flexible, muscle-powered pump that could be used for medicalapplications and soft robotics. Graduate student Janna Nawroth worked with John Dabiri, professor of aeronautics and bioengineering at Caltech, and Kit Parker, Tarr Family Professor of Bioengineering and Applied Physics at Harvard, to elucidate how the jellyfish body creates flows and eddies useful for pumping, propulsion, and feeding. In this video, the teamexplains how and why they developed a technology that turns silicone rubber and lab-grown muscle tissue into jellyfish-like fluid pumps and swimmers–advancing the design of muscular pumps for biomedical applications.

What's New

Welcome, Dr. Suji Choi and Dr. Sarah Motta! October 5th, 2018

The DBG would like to extend a warm welcome to our new postdoctoral fellows, Suji Choi and Sarah Motta. Suji joins us from Seoul National University, where she completed her Ph.D. in Chemical and Biological Engineering in Prof. Dae-hyeong Kim’s Flextronics group. Sarah recently completed her Ph.D. at the Institute for Regenerative Medicine in Zurich in Tissue Engineering and Regenerative Medicine. We are excited for both of them to join us!

Welcome, Huibin! September 5th, 2018

The DBG welcomes Post-Doctoral Fellow Huibin Chang, who joined the group September 1. Huibin joins us from Georgia Tech, where he recently completed his Ph.D. in Materials Science and Engineering. Welcome, Huibin!

Congressional Staffers Visit the DBG August 31st, 2018

The DBG welcomed several opportunities so far in 2018 to discuss Federal budget appropriations to the National Institutes of Health and the Department of Defense. After discussions with staffers from Senator Elizabeth Warren (D-MA), Congresswoman Katherine Clark (D-MA), and the Senate Armed Services Committee regarding our experiences with the various offices of the DoD and NIH, we showed our work and introduced the professional staff and trainees within the laboratory. Over the years we have enjoyed interactions with a variety of elected officials and Congressional staffers who have requested to hear about our work and the challenges with funding research at the cutting edge.
