IMID is a specialized academic event related to information display, organized by the Korean Information Display Society (KIDS) and the Society for Information Display (SID) in the United States. This year, the event attracted 2,700 participants.

Seong Baeksang received the KIDS Awards for presenting a research paper titled "Durable and Stretchable Skin-Like Strain Sensor with UV Protection and Antibacterial Functionality."

Through his research, Seong Baeksang overcame issues that can arise when attaching conventional stretchable strain sensors to the skin by optimizing the composition of the eco-friendly materials tannic acid and cellulose.

Tannic acid, used as an additive, increases resistance to moisture such as sweat and enhances antibacterial properties when attached to the skin, while also improving resistance to external ultraviolet rays.

Based on this, Seong Baeksang increased the stability of repeated operations, a mechanical characteristic of stretchable strain sensors, by enhancing hydrogen bonding between tannic acid and cellulose.

This research was supported by the National Research Foundation of Korea (NRF).
