How seeds implant themselves in soil can seem magical. During rain or high humidity, the corkscrew-like stalk of Erodium unwinds and twists the seed into the soil, where it can take root and is safe from hungry birds and harsh environmental conditions. Inspired by Erodium’s magic, researchers at Carnegie Mellon University collaborated with Syracuse University, … Read more
Climate change is forcing us to reshape our relationship with water. Collecting atmospheric water could help us adapt to both severe dry spells and inundating amounts of precipitation by providing a source of freshwater or dehumidifying humid places. The Yang lab and collaborators have created a kirigami device utilizing the geometry of simple materials to … Read more
For many breast cancer patients, the road to recovery may present hidden complications related to breast reconstruction following a mastectomy. The insertion of implants can lead to implant malposition, a condition that affects a significant number of patients even years after surgery. Now, the Yang lab and collaborators have used the principles of a papercutting … Read more
When a metacap “snaps”, it pops open and closed, pushing air back and forth. This snapping allows a soft robot to propel and grip without any electronics. The new ribbed metacaps permit unprecedented levels of control and speed, enabling robots delicate enough to gently grasp a ripe strawberry and powerful enough to swim through choppy, … Read more
The team’s work takes inspiration from kirigami, an East Asian papercutting art, to create a mathematically sound method of cutting and stacking flat materials into durable curved objects. The advance addresses a longstanding blind spot at the intersection of mechanical engineering and materials science: Hardwearing materials with high mechanical integrity lose strength when manipulated into … Read more
Most adhesives for wound dressings have either been too weak to keep wounds sealed, or too strong to be painlessly peeled off. An innovative adhesive for closing wounds is twice as strong as a commonly used commercial product — even to hairy skin —but lifts off when submerged in water. More
