Inspired by jellyfish, the research team of the National University of Singapore (NUS) has developed a self-healing transparent electronic skin, which is expected to be applied to waterproof touch screens and underwater flexible robots in the future. The electronic skin, jointly developed by the NUS material science and engineering research team, Tsinghua University in Beijing and the University of California Riverside, is as transparent, waterproof, malleable, touch sensitive and self-healing in the water environment as jellyfish.

The team explained that this is a gel containing fluorocarbon (Fluorocarbon) polymer, containing high fluorine content ionic liquids. When the above polymer and ionic liquid touch together, they have self-healing ability through reversible ion dipole interaction. Assistant Professor Benjamin Tee pointed out that the biggest advantage of their electronic skin is that they can maintain their original shape both in the dry and wet environment and operate in seawater or acid and alkali environment. Unlike general conductive polymer gel, they will expand when they enter the water.

Tee also pointed out that the materials they developed can produce transparent circuit boards through 3D printing, which has the potential to be applied to flexible robots, amphibious robots and waterproof electronic products. In addition, the self-healing ability of this new material also helps to reduce electronic waste. The research team is currently studying the use of this new material to create innovative optoelectronic devices, which are expected to be applied to new man-machine communication interfaces in the future.
