Hanyang University announced on March 15 that a co-research team of Professor Kim Do-hwan at Hanyang University and Professor Ying Wu-bin at KAIST developed an electronic skin based on a naturally simulated piezoelectric ion elastomer that which damages and haptic sensors are restored by themselves in the atmosphere and 토토사이트 롤링.

To develop an electronic skin that can be applied to a marine expedition robot skin, wearable skincare, and 토토사이트 롤링 environment monitoring, developing a material that restores itself from external damages and can detect the surrounding environment of a user was necessary. However, even though many materials cure wounds in the atmosphere, there was a difficulty in creating a material that cures physical damage fast 토토사이트 롤링.

The 토토사이트 롤링 team got an idea from the detecting mechanism of self-healing and external stimuli in the aquatic environment of marine invertebrates, especially cephalopod skin. The team developed a fast self-healing piezoelectric elastomer with a dynamic hydrophobic-hydrolytic domain by introducing a carbon-fluorine group exhibiting abundant hydrophobicity in polyurethane and a boronate ster bond capable of hydrolysis and esterification.

Professor Kim Do-hwan of Hanyang University said, "From this research, the piezo-ionic elastomer we developed showed an outstanding self-healing capability under water by preventing complete hydrolysis of the boronate ester bond through the dynamic hydrophobic-hydrolysis domain and a technique for showing tactile function underwater through ion-dipole interactions between carbon-fluorine and ions and restoring itself after being damaged. This research result is expected to be used as a skin model applied to new haptic interfaces such as wearable healthcare devices and marine expedition robot skin.

The 토토사이트 롤링 result was conducted with the support of the Ministry of Science and ICT, the National 토토사이트 롤링 Foundation, the Nano and Materials Development Project, the High-End Convergence Technology Development Project, and the Korea-China Cooperative 토토사이트 롤링 Project.

The research (Title: Ultrafast 토토사이트 롤링 self-healing piezo-ionic elastomer via dynamic hydrophobic-hydrolytic domains) was published online in Nature Communications on March 8 and is applying for a patent with its relevant technology.
