Material scientists have recently developed novel materials with a variety of advantageous properties that have the potential to improve the performance of various devices and technologies. Hydrogel-based fibers and synthetic skins, which could be used to make soft humanoid robots, prosthetics, and even comfortable smart clothes or wearable devices, are included in this category. New robust, self-healing, and crack-resistant hydrogel-based microfibers were recently developed by researchers at Donghua University in China. A method that was influenced by the way spiders spin their webs was used to create these microfibers, which were first published in Nature Communications. Shengtong Sun, one of
