A remarkable development in electronic skin(e-skin)technology may change how humans interact with digital devices. Researchers at Helmholtz-Zentrum Dresden-Rossendorf have created a super thin, transparent e-skin which can precisely detect and track magnetic fields, opening possibilities ranging from underwater smartphone operation to enhanced virtual reality experiences.Traditional e-skins, while innovative, have been limited by their dependence on multiple sensors and large power sources. "Previous designs were like smartphone touchscreens with countless individual sensors," explained Dr. Denys Makarov, lead researcher at the Institute of Ion Beam Physics. "Our major breakthrough was developing a whole system that imitates how human skin actually works. This is mainly what sets it apart from previous e-skins."The new e-skin consists of a remarkably thin membrane (膜), which is both flexible and breathable. Unlike earlier versions that could cause discomfort to real skin, this design allows air and moisture to pass through, making it comfortable to wear. The key innovation is a magnetosensitive functional layer that serves as a single, continuous sensor surface.Pavlo Makushko, the study's first author, compares the technology to human biology, "Just as our skin sends all touch signals through nerves to the brain, our e-skin uses one central processor to interpret magnetic signals across its entire surface." This efficient design significantly reduces energy consumption compared to conventional e-skins.The research team adapted principles from medical tomography (影像) to achieve unheard-of precision in locating magnetic signals. This approach overcame previous limitations in sensitivity that had prevented similar developments.Looking ahead, the researchers imagine this technology bridging the gap between human and machine interaction. "It creates a completely new communication channel," Makarov noted, emphasizing how the e-skin's magnetic sensing avoids disturbance from other electronics. As development continues, we may soon see this innovative e-skin integrated into everything from wearable tech to advanced robotics. （1） What can be inferred about the new e-skin in paragraph 1? A .
