Abstract: A recyclable vitrimer polymer composition includes: a first monomer containing at least one amine group at the terminal thereof; and a second monomer containing at least one acrylate group at the terminal thereof. The N—H group of the first monomer and the acrylate group of the second monomer react with each other in a ratio of 1:0.5 to 1.5.

Abstract: A polymer having a UV-responsive self-healing function at room temperature and its manufacturing method are disclosed herein. More specifically, the solid dynamic crosslinked polymer with a UV-responsive self-healing function is capable of being repaired and reprocessed through a dynamic exchange reaction of disulfide induced under exposure to UV radiation at ambient temperature when damaged after curing. The novel polymer with a UV-responsive self-healing function is capable of self-healing simply through UV exposure at ambient temperature. Therefore, it can be utilized in the recycling of thermosetting resins that are environmentally challenging to recycle in the plastic industry, and furthermore, serve as an alternative to address various environmental issues.

Abstract: Provided is a cochlear implant device with a glasses shape. The disclosed cochlear implant device improves body wearability and aesthetic effects by designing the cochlear implant device to have a glasses shape, and achieves alignment of a receiver coil implanted into the body and a transmission coil outside the body without using a magnet because the transmission coil is integrally provided at an end of a glasses temple such that a region of a body with which the transmission coil comes into contact is changed according to a bending degree of the glasses temple.
