Research Interests

INTELLIGENT MULTISCALE STRUCTURING & PROGRAMMABLE NANO/MICRO-ARCHITECTURES
Our vision revolves around several platforms for highly effective systems with a intelligent nature-inspired approach, an interfacial assembly and combination for multi-functional systems and, large-area processing with smart materials. Structured stimuli responsive nano architecture will contain nano /micro patterns, structural interlocking, and molecular level assembly with various fictionalized materials. The programmable nano-architectures of soft materials are investigated with understanding of detail physics and interactions, including reversible intermolecular forces with 3D nano/micro-architectures for bio-inspired reversible wet/dry bio-adhesive, super-wettability, bioelectronics, and soft robotics

INTELLIGENT MULTIPLEX SOFT ELECTRONICS
Recently, intelligent stretchable electronics and systems are essential components in the development of artificial systems that can mimic the complex characteristics of the human organs. We intended to focus on multiplex and stretchable devices for tools of E-skins, wearable device, bio-integrative applications and healthcare systems. For diagnosis and therapy, intelligent stretchable bioelectronics and systems with bioinspired multiscale hierarchical architectures are developed through novel top-down, bottom-up, and combined approaches.
