The New 'ionic skins' are designed to intelligently mimic the sensing characteristics of human skin, and a number of ionic conductors (such as ionic liquids, metal salt ions and conducting polymers) have been used to realize bionic skins with the sensory characteristics of human skin.

Recently, based on the previous research on ultra-long hydroxyapatite nanowires,the team of professor Hu Ning of our university and associate professor Ning Huiming of Chongqing University has developed a transparent and highly ion-conducting hydrogel combined with the original method of oxidizing and depositing tannic acid on site, which integrates multi-purpose sensing performance, ultraviolet filtering function, high temperature water retention, low temperature antifreeze and biocompatibility sex in one. It can be used in the field of ion skin.
