<p>➀ A research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has developed an electronic skin capable of sensing and tracking magnetic fields with a single global sensor. This technology could enable new applications in virtual reality and underwater smartphone interaction.</p><p>➁ The e-skin is lightweight, transparent, and breathable, imitating the interaction between real skin and the brain. It uses a magnetosensitive functional layer as a global sensor surface, improving energy efficiency and mimicking real skin's functionality.</p><p>➂ The technology uses tomography, a method also used in medical MRI or CT scans, to reconstruct the position of signals, making it suitable for applications in robotics and human-machine interaction.</p>
