Paper Skin Mimics the Real Thing

Human skin's natural ability to feel sensations such as touch and temperature difference is not easily replicated with artificial materials in the research lab. That challenge did not stop a Saudi Arabian research team from using cheap household items to make a "paper skin" that mimics many sensory functions of human skin. The artificial skin may represent the first single sensing platform capable of simultaneously measuring pressure, touch, proximity, temperature, humidity, flow, and pH levels. Previously, researchers have tried using exotic materials such as carbon nanotubes or silver nanoparticles to create sensors capable of measuring just a few of those things. By comparison, the team at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia used common off-the-shelf materials such as paper sticky notes, sponges, napkins and aluminum foil.
