MIT developed electronic skin that can sense signals, and researchers at Stanford University have now come up with innovative spray-on smart skin that uses AI to sense what you’ll type on a computer keyboard. Put simply, this biocompatible material can be sprayed on to the back of your hand like sunscreen and an electrical network then senses when the skin stretches to make these predictions.
Machine learning algorithms translates these movements made on a virtual keyboard into actual letters on screen. Is this spray-on smart skin safe? Well, it’s essentially a stretchable nanomesh that moves with your skin and can be easily removed. In the future, the researchers hope that this smart skin can be used for virtual reality applications and on smartphones.
With the help of machine learning, electronic devices—including electronic gloves and electronic skins—can track the movement of human hands and perform tasks such as object and gesture recognition. 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,” said Zhenan Bao, a K.K. Lee Professor of Chemical Engineering at Stanford University.
