Stanford researchers have developed a smart skin that is sprayed on the user's arm allowing him to type using a virtual QWERTY or play video games without controllers.
), Stanford University researchers have been working on a smart skin that will use artificial intelligence to interpret a person's movements. This smart skin can be sprayed out of a can like shaving cream. The spray is called a"nanomesh," and it is a mesh-like stretchable material that can move and bend with your skin. It uses tiny electrical sensors that pick up on your movements and send them to a neuro processing unit for interpretation.
The sensitive mesh network is embedded in polyurethane and is made up of millions of nanowires coated in gold and silver. The mesh stays on the skin until it is rubbed with soap and water. It also conforms to the wrinkles and folds that every individual finger has. A lightweight Bluetooth transmitter is attached to the mesh allowing for the transmission of signal changes.
Zhenan Bao, a chemical engineering professor at Stanford and senior author of the study, said,"As the fingers bend and twist, the nanowires in the mesh get squeezed together and stretched apart, changing the electrical conductivity of the mesh. These changes can be measured and analyzed to tell us precisely how a hand or a finger or a joint is moving.
Let's look at how the virtual QWERTY would work. Using machine learning, an algorithm can learn the motion needed to type the letter"X" on a keyboard based on the patterns of electrical conductivity. Once the algorithm is"trained" to recognize the algorithm for all letters, numbers, punctuation, etc., the physical keyboard is no longer necessary.
