Meet Dart, BU's "Stranger Things"-Inspired Soft Robot
From the slithering of snakes to the crawling of octopuses, the field of soft robotics has often taken cues from the natural world. But what about the supernatural? Boston University’s Morphable Biorobotics Lab is doing just that with [...]“Dart,†a new soft robot whose nickname was inspired by its resemblance to creatures from the popular Netflix series “Stranger Things.â€

Intelligent Metamaterials for Enhanced MRI
Boston University researchers have developed a new, “intelligent†metamaterial that costs less than ten bucks to build could revolutionize magnetic resonance imaging (MRI), making the entire MRI process faster, safer, and more accessible [...]to patients around the world. The technology, which builds on previous metamaterial work by the team, was described in a new paper in "Advanced Materials."

How Magnetic Metamaterial Improves MRI
BU researchers Xin Zhang, Stephan Anderson, and their team at the Boston University Photonics Center, Guangwu Duan and Xiaoguang Zhao, designed a new magnetic metamaterial that can create clearer images at more than double the speed of a standard MRI [...]scanner. In this video, learn how their magnetic metamaterial works.

Schon Horology: The Art of Watchmaking
Like most engineers, Boston University alumni Ian Schon (ENG'12) has always loved tinkering. He began tinkering with watches in 2013, after purchasing a watch online that was not as advertised. He took it apart and decided to use the metalworking and [...]machining skills he had developed as a mechanical engineering student at BU to build a new case for it. He opened Schon Horology earlier this year to sell wristwatches he designs and makes himself.
In this video, follow Ian Schon's deeply personal journey into the world of horology as he designs and machines his own watches in his Allston, MA studio.

MORPH: A new soft material microfabrication process
Researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering, Harvard John A. Paulson School of Engineering and Applied Sciences, and Boston University have used a new integrated fabrication process to create robotic soft [...]spiders—inspired by the millimeter-sized colorful Australian peacock spider—from a single elastic material with body-shaping, motion, and color features. Sheila Russo and Tommaso Ranzani, now assistant professors at Boston University, are coauthors of the study -- https://wyss.harvard.edu/soft-multi-functional-robots-get-really-small/

Battling Drug Subs with Boogie Boards
Since the early 1990s, at least 60 “drug subs†have been captured. They’re sophisticated contraptions, with multiple crew members and GPS navigation—and their sole purpose is to sneak massive amounts of cocaine, heroin, and [...]other illegal drugs into the country. They’re exceptionally good at their job. To combat this menace, Boston University engineering professor Greg McDaniel is building a swarm of autonomous microboats. These machines would travel around an area of open ocean independently, listening for suspicious sounds. If an individual drone hears a noise, it can alert its robotic colleagues and invite them to collectively hone in on a target. This could help detect narco-subs and other small underwater threats more reliably—making the concept particularly attractive to the US Navy.
