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.

Conformably Skin-adherent Piezoelectric Patch with Bioinspired Hierarchically-arrayed Microsuckers enables Physical Energy Amplification

Da Wan Kim, Hyunseung Kim, Geon-Tae Hwang, Sung Beom Cho, Seung Hwan Jeon, Hyeon Woo Kim, Chang Kyu Jeong*, Sungwoo Chun*, Changhyun Pang*

About the Cover:

A hierarchically arrayed octopus-inspired pattern (h-OP) formed on piezoelectric composite patch devices is developed. The h-OP enables robust wet adhesion to skin because its dome-like architecture achieves interfacial adhesion by generating capillarity-assisted suction stress. The h-OP devices demonstrated stable adhesion and high energy generation efficiency, even on the wet skin.

Tough Carbon Nanotube-Implanted Bioinspired Three-Dimensional Electrical Adhesive for Isotropically Stretchable Water-Repellent Bioelectronics

Hyeongho Min, Sangyul Baik, Jinhyung Kim, Jihyun Lee, Bo-Gyu Bok, Jin Ho Song, Min-Seok Kim*, Changhyun Pang*


About the Cover:

We report a highly skin-adaptive, sweat-drainable patch with an isotropically stretchable and durable nanotube-implanted electrode via a selective-transfer technique for multiplexed bioelectronics. Inspired by the wrinkled suction cups in the forelegs of diving beetles, the water-repellent adhesive patch can stably monitor multiple biosignals (electrocardiography and skin temperature) without delamination on skin in sweaty and even harsh dynamic conditions.

Electrostatic-Mechanical Synergistic In Situ Multiscale Tissue Adhesion for Sustainable Residue-Free Bioelectronics Interfaces

Da Wan Kim, Kang-Il Song, Duhwan Seong, Yeon Soo Lee, Sangyul Baik, Jin Ho Song, Heon Joon Lee, Donghee Son*, and Changhyun Pang*


About the Cover:

This patch successfully demonstrates reliable real-time measurements of electrophysiological signals generated by various tissues ranging from rodent sciatic nerve, muscle, brain, and human skin.
