Performance evaluation of E-Skin for structural deformation detection

Abstract

Damage detection systems of structures are considered one of the most important technologies for ensuring the safety of structures in various types of research. Among them, carbon nanotube polymer composite, which is easy to apply to structures and has no size limitations, has been reported as one of the most suitable methods for SHM systems. We developed E-Skin (Electronic Skin), a carbon nanotube polymer composite. Then, we confirmed the electrical change of E-Skin due to mechanical deformation. Mechanical deformation led to electrical changes in the E-Skin. Based on this phenomenon, we applied E-skin to the structure and checked the electrical changes of E-skin due to cracks and loads. We aim to develop a system that can monitor cracks and various loads of structures in real-time using E-Skin. © 2022 Jung et al.
