Through the convergence research between JNU Basic Science Research Center and Jeju Seagrent Center, a research team led by JNU Prof. Bae Jin-ho, (Department of Ocean System Engineering), Director of BK+ Big Data-Based Marine Convergence Professional Human Resources Project Group, has developed an electronic material by using sargassum horneri, that can be easily obtained in the sea of Jeju, as an electronic device.

The research paper (Corresponding author, Prof. Bae Jin-ho, First author Patil Swaffnil, Ph.D. graduate student and co-first author Norman Muhammad Ph.D. graduate student at JNU) has appeared in "Nano Today (57 volumes), one of the world's best journals.

Considered a headache for the Jeju sea in winter, Sargassum horneri is expensive to collect and dispose of. The research team used Sargassum horneri to extract electronic materials and identify various electrical properties for the first time. Using these characteristics, the team applied them for the first time to various electronic devices such as triboelectric nanogenerators, temperature and humidity sensors, supercapacitors, and electrodes for hydrogen production, and published the results in Nano Today.

The title of the paper is "Unveiling the Marine Sargassum Horneri Material for Energy & Active Sensor Devices: Towards Multitasking Approaches." This research was conducted with the support of the Mid-career Researcher Program of the Ministry of Science and ICT, the Jeju Sea Grant Center of the Ministry of Oceans and Fisheries, and the Jeju National University Basic Science Research Institute Autonomous Key Research Support Group of the Ministry of Education.

This study showed excellent characteristics by applying electronic materials extracted from Sargassum horneri to the electrodes of triboelectric nanogenerators, temperature and humidity sensors, supercapacitors, and electrolytic cells for hydrogen production. These research results demonstrate the industrialization potential of Sargassum horneri as an electronic component. Therefore, it is expected that this brown seaweed, a waste product from the Jeju sea, will play an important role as an electronic material.
