About this video

A ship in a storm is a lot like a paperclip that you’ve bent back and forth too many times: repeated strain can cause catastrophic failure, So U-M researchers have designed a simple mechanical sensor that can precisely measure that strain, predicting structural failures before they occur and helping to keep military and commercial sailors safe.

Made of 3D printed plastic, the sensors cost a few dollars apiece and can be quickly attached with magnets. Unlike current sensors, they don’t require electrical or data connections, and they’re easy to customize for specific applications, including monitoring damage after an accident, measuring routine wear and tear and making the shipbuilding process more precise. Mark Groden, the sensor’s inventor and a graduate researcher at the U-M college of Naval Architecture & Marine Engineering, predicts they’ll be in use within the next year.

About the Professor

Mark Groden is a Graduate Student Research Assistant at the University of Michigan’s Naval Architecture and Marine Engineering department under the guidance of Dr. Matthew Collette. He graduated in 2012 magna cum laude with a BS in Naval Architecture and Marine Engineering and the College of Engineering’s Distinguished Undergraduate Academic Achievement Award. During his undergraduate career Mark served various roles within the Society of Naval Architects and Marine Engineers, most recently as the Chairman of the Student Steering Committee and currently serves on the SNAME Nominating Committee. His PhD is focused on structural reliability and application of Bayesian Networks.
