Researchers at King Abdullah University of Science and Technology have recently developed a flexible and imperceptible magnetic skin that adds permanent magnetic properties to all surfaces to which it is applied. This artificial skin could have numerous interesting applications. For instance, it could enable the development of more effective tools to aid people with disabilities, help biomedical professionals to monitor their patients' vital signs, and pave the way for new consumer tech.
The artificial skin is magnetic, thin and highly flexible. When it is worn by a human user, it can be easily tracked by a nearby magnetic sensor (i.e. if a user wears it on his eyelid, it allows for his eye movements to be tracked or if worn on fingers, it can help to monitor a person's physiological responses or even to control switches without touching them). The magnetic skin is easy to assemble, as it is made by mixing an elastomer matrix with magnetic powder and then drying this mixture at room temperature.
