New foam technology to lead advances in medical devices and protective equipment [news release]
From the 26 May 2015 Florida State University news release
Foam. We wear it. We sit on it. We sleep on it. We even use it to protect ourselves.
Whether it’s a football helmet, hospital bed, knee pad or body armor, the foam it contains plays a critical role in making that product both comfortable and safe. But can that foam be transformed into something significantly better, safer and more comfortable?
Changchun “Chad” Zeng with Florida State University’s High Performance Materials Institute (HPMI) says yes, and his brand new, high-performing auxetic foam is proving the point as it heads to the marketplace through a license agreement with Auxadyne LLC.
“We know what is not working with current products and technology, and what it is going to take to make it better,” said Zeng. “For example, the socks that amputees currently use to attach prosthetic devices do not adjust to limb shape and volume, creating lots of problems. My invention solves those issues.”
Part of what makes Zeng’s auxetic foam truly unique is its ability to get thicker, rather than thinner, when stretched. In practical terms, this counter-intuitive behavior, totally opposite to that of conventional foam, leads to many enhanced materials properties including a better and more comfortable fit that adjusts on the fly.
