A nature-inspired leap in water harvesting technology

A nature-inspired leap in water harvesting technology

Penn Engineering’s Shu Yang and postdoctoral fellow Yunchan Lee are working to develop a new material and device that imitate raspberries and sunflowers. Together, these bio-inspired forms make clean, sustainable water harvesting possible by using just the moisture in the air and the heat of the sun.
