Scientists in China and South Korea developed a new kind of "iontronic skin" that can repair itself at what they call an "ultrafast" speed.
According to a research paper published on Nature Communications, the skin can automatically self-heal as fast as 4.3 micrometers per minute and as effective as 91 percent in an hour.
The iontronic skin can respond to pressure changes like real human skin. The paper described its sensitivity as "excellent."
The scientists, who work at Ningbo Institute of Materials Technology and Engineering, Hanyang University and Chungnam National University, made this new skin possible by introducing Cl-functionalized groups into a polyurethane matrix during the design process.
They said in the paper that the skin has potential to be used in the touchscreen of wearable electronic gadgets. It may also be applied on other human–machine interfaces. (CGTN)
To understand the defect-GB interaction processes and reveal the across-scale self-healing mechanism in NCs, collaborating with researchers from Institute of Plasma Physics, Hefei Institutes of Physical Science, a nuclear material study team led by LIU Changsong and FANG Qianfeng from Institute of Solid State Physics, Hefei Institutes of Physical Science of the Chinese Academy of Sciences, developed a set of software to investigate radiation effects in NCs.
A researcher group led by Prof. ZHU Jin at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), synthesized a novel self-healing ionic polyurethane (i-PU), thus achieving an ionic skin (I-Skin) with excellent sensing performance.
