OVERVIEW

  • Our vision revolves around several platforms for highly  effective systems  with a nature inspired approach, an interfacial assembly and combination for multi-functional systems and, large-area processing. 

  •  Structured stimuli responsive nano architectures include particular nano/micro patterns, structural interlocking, and molecular level assembly.   

  • The programmable nano-architectures are investigated with understanding of detail physics and interactions in nature for bio-integrative, and energy, environmental applications.

  • We intend to focus on multiplex and flexible devices for tools  of intelligent bioelectronics and medical devices interfaced with artificial intelligence.

Triboelectric Energy: A Micropillar‐Assisted Versatile Strategy for Highly Sensitive and Efficient Triboelectric Energy Generation under In‐Plane Stimuli (Adv. Mater. 2/2020)

Changhyun Pang, Sung Beom Cho, and Sungwoo Chun report a novel and general method for efficient triboelectric energy generation, by assembling artificial micropillars on typical triboelectric nanogenerator devices. The hairy‐structured devices can efficiently harvest electrical energy from in‐plane stimuli such as contact rubbing pressure or noncontact airflow, which works even for extremely small mechanical variations (<0.2 Pa) efficiently.

Spray Coating Technologies: Conductive Hierarchical Hairy Fibers for Highly Sensitive, Stretchable, and Water‐Resistant Multimodal Gesture‐Distinguishable Sensor, VR Applications (Adv. Funct. Mater. 50/2019)

Changhyun Pang, and co‐workers develop conductive hierarchical hairy fibers for a highly sensitive, stretchable, and water‐resistant multimodal gesture‐distinguishable sensor. With multimodal resistance and three‐dimensional microhairy structures on the conductive fiber, the sensor detects three distinct stimuli from the human body. Due to high sensitivity and distinguishability, the presented device is anticipated to be useful for virtual reality applications.
