[Topic 1] Our laboratory operates at the intersection of precision nanoarchitectonics and intelligent sensor systems to pioneer advanced, real-world sensing technologies. We engineer high-performance platforms by designing nanoscale architectures—specifically utilizing metal oxides and sulfides—through atomic-level hybridization. These materials are seamlessly integrated into scalable MEMS/NEMS and skin-interfaced electronics, including wearable patches, smart gloves, and watch-type sensors for continuous physiological monitoring. To transform raw data into actionable insights, we employ machine learning (ML), artificial intelligence (AI), and advanced signal processing (e.g., PCA), enabling autonomous and adaptive sensing ecosystems. Our mission is to bridge fundamental materials science with intelligent system design, shaping the future of smart healthcare, environmental monitoring, and human-centered IoT platforms.

[Topic 2] Our laboratory also explores a specialized branch of solution-based nanoarchitectonics, engineering hybrid materials with tailored properties through the use of pre-defined nanostructured templates. This approach enables the controlled synthesis of materials with precisely tuned physicochemical characteristics by integrating bottom-up solution processes with top-down fabrication techniques. By utilizing patterned substrates (e.g., ZnO, TiN, Au, and Cu films), we employ scalable techniques such as chemical doping and hierarchical layer-by-layer deposition to create complex architectures, including artificially controlled structures and porous metal frameworks. These platforms serve as a robust foundation for integrating transition metal chalcogenides (e.g., CuS, ZnS, NiS) with high surface area and exceptional crystallographic control. Such optimized systems offer a versatile route to next-generation multifunctional devices, bridging the gap between high-throughput production and fundamental nanoscale design.
