Ultrahard, Yet Flexible Hybrid Nanocomposite Reinforced by 3D Inorganic Nanoshell Structures for Flexible Protective Film
Prof. S. Jeon, B.-S. Bae, S.M. Han, and J.-W. Hong’s groups have developed a nontrivial type of nanocomposite combining organic-inorganic (O-I) hybrid materials with 3D oxide nanostructure. The 3D hybrid nanocomposite film simultaneously achieves superior hardness, optical transparency, and flexibility....read more

Highly Stretchable Strain Sensor based on 3D Nanostructure for Human Motion Detection System
The demand for wearable strain gauges that can detect dynamic human motions is growing in the area of healthcare technology. However, the realization of efficient sensing materials for the effective detection of human motions in daily life is technically challenging due to the absence of optimally designed electrodes. Here, we propose a novel concept to overcome the intrinsic limits of conventional strain sensors based on planar electrodes by developing highly periodic and three-dimensional (3D) bicontinuous nanoporous electrodes. The 3D structural platform allows the fabrication of a strain sensor with robust properties, such as a gauge factor of up to 134 at a tensile strain of 40%, a widened detection range of up to 160%, and a cyclic property of over 1000 cycles. Collectively, this study provides new design opportunities for a highly efficient sensing system that finely captures human motions, including phonations and joint movements....read more
