When it comes to taking up room without adding too much weight, the bubble can’t be beat. Because they are mostly air, they’re ultra-lightweight and can expand to fill any given space. Researchers at the University of Pennsylvania and the Korea Institute of Science and Technology (KIST) found a way to exploit these properties of … Read more
A collaboration between biologists and materials scientists at the University of Pennsylvania is yielding new insights into the wings of the “skipper butterfly” in the Costa Rican rainforest. What they learn could lead to technological advancements in systems ranging from power-efficient computer displays to sensors to energy efficient buildings, windows and vehicles. Read more
Wearable technology requires materials that are both flexible and functional, so developers often look to polymers or to make harder materials as thin as possible. “So we’re taking inspiration from clothing” to make a new kind of wearable health tracking device that gathers information from its wearer through his or her sweat. Instead of just wicking … Read more
The precise link between concussions in sports, especially at the youth level, and traumatic brain injurie by soldiers is still being explored. Unfortunately, unlike a broken bone or a torn ligament, concussions are invisible and tricky to diagnose. Tthe Penn team in collaboration with Gang Feng’s group at Villanova University and Jie Yin’s group at … Read more
Commonplace as they are, windows are an important piece of technology. Beyond architectural aesthetics, a building’s ecological footprint depends heavily on how its internal light and heat are managed. With this in mind, researchers from around the world are trying to make windows “smarter” by tailoring their properties to be more responsive and finely tuned … Read more
