Pukyong National University Professor Kim Jong-Hyeong ‘Draws Attention’ for Research on Eco-Friendly Semiconductors and Ultra-Sensitive Sensors

- Consecutive publications in SCIE journals; global research achievements expanded with support from the RISE program

Professor Kim Jong-Hyeong (Major in Materials Engineering) at Pukyong National University has recently gained international attention by presenting a series of notable research achievements in the fields of eco-friendly semiconductor materials and next-generation sensor technologies.

Professor Kim recently published a paper titled “Dissolution study of biodegradable Magnesium Silicide thin films for transient electronic applications” in the renowned SCIE-indexed international journal <Advanced Science>, demonstrating that magnesium silicide (Mg₂Si)―an eco-friendly semiconductor material that operates stably for a certain period and then dissolves without a trace when exposed to specific environmental conditions―can function as a practically applicable semiconductor. The study has been recognized for its academic and industrial significance, as it experimentally verified the feasibility of biodegradable electronic devices (Transient Electronics).

In addition, another paper titled “Synergistic Meta-Perforated Substrates for Hypersensitive Crack-Based Strain Sensors,” which maximizes ultra-fine strain detection performance through a specialized geometric design applied to the substrate, is also scheduled to be published in the same journal. The study presents the potential of ultra-sensitive sensor technology applicable to a wide range of fields, including wearable devices, precision healthcare monitoring, and next-generation robotic sensors.

Professor Kim Jong-Hyeong has continued to achieve internationally recognized research outcomes in next-generation electronics and sensor technologies, following the publication of his study on solar-powered levitating ultralight nanolattice structures in the globally renowned journal <Nature> in August last year.

These research achievements were supported by the “Global Collaborative Research Expansion Program in Specialized Fields” operated by the RISE Program Office of Pukyong National University. The program has been strengthening global research networks by providing funding for international joint research with leading overseas universities and global companies, as well as for the generation of collaborative research outcomes. Through this initiative, the university actively supports the global expansion of its research achievements and their connection to technology commercialization.

As a research-oriented university, Pukyong National University continues to promote various initiatives aimed at nurturing research talent and strengthening research and development capabilities to lead the future industries of the region. <Pukyong Today>
