Composite Hydrogel for Pressure-Vibration Sensor Based on Inner Structure Hydrophobicity |
| 초록 |
A reversible shift of pressure sensor using a controllable hydrophilic-hydrophobic of a hydrogel has been extensively studied due to hydrogel features that could acquire electronic signal during mechanical deformation. In this study, we invent a carbon dots nanoparticle with high hydrophobicity (CD) that would be loaded into polyvinyl alcohol (PVA) and catechol-conjugated chitosan hydrogel matrix for pressure sensing application. The hydrophobicity of the incorporated CD becomes an important factor that affects the mechanical performance and electronic signal. The volume transition happens during signal acquisition owing to the effect of the nanoparticle to the hydrogel density and structure. Additionally, various approaches could be implemented to the hydrogel, which opens the enormous opportunity for multiple purposes such as wearable electronic skin and real-time clinical health-care monitoring. This work was supported by Korea National University of Transportation in 2021. |
