Abstract: A self-healing conjugated polymer is disclosed. The self-healing conjugated polymer has hydrogen bonding functional groups introduced into its side chains. Due to this structure, the conjugated polymer is imparted with the ability to recover through self-healing while maintaining its inherent properties (for example, physical and electrical properties). Based on this effective self-healing ability, the conjugated polymer is expected to find application as a biomaterial, a pharmaceutical material, a nonlinear optical material or an organic electronic material.

Abstract: A bidirectional self-healing neural interface includes a first elastic substrate; a neural electrode disposed on the first elastic substrate and comprising a conductive polymer composite; and a second elastic substrate disposed on the neural electrode. The conductive polymer composite includes a matrix formed of a self-healing polymer material; and a plurality of electrical conductor clusters distributed in the matrix. Each of the electrical conductor clusters includes particles of a first electrical conductor; and a plurality of particles of a second electrical conductor formed of the same material as that of the first electrical conductor, distributed around each of the particles of the first electrical conductor, and having sizes that are smaller than those of the particles of the first electrical conductor. The first electrical conductor is a source for generating the second electrical conductor. The neural interface has excellent elasticity, electrical conductivity that is improved by deformation, and is self-healing.

Abstract: Disclosed are a method of transmitting image data having a hybrid resolution and a method of generating a hybrid-resolution image. A main region of an original image is transmitted as a high-resolution image and the remaining regions are transmitted as a low-resolution background image. Accordingly, an amount of data to be transmitted is able to be reduced.

Abstract: A user wears a virtual reality mask (VR mask) (100) and then watches a virtual reality image. The VR mask (100) blocks light incident from the outside. When the user wears the VR mask (100), the user cannot discover an obstacle (500) positioned outside the VR mask (100). The user may collide with the obstacle (500) and may be injured by the obstacle (500). Accordingly, in order to prevent injury to the user who uses the VR mask (100), it is necessary to make the user recognize the obstacle (500) positioned outside the VR mask (100). In order to recognize an obstacle, a virtual reality image and the obstacle may be displayed together, or the amount of light incident from the outside may be adjusted.
