Setaria Viridis-like ZnO Nanorod and Its Filament Sensor's Preparation,Properties and Applications
摘要
Abstract
To address the common issues of insufficient mechanical properties and limited accuracy in moni-toring minor deformations in hydrogel-based strain sensors,nano zinc oxide with a structure mimicking"setaria viridis"was synthesized via a hydrothermal method and composited with polyvinyl alcohol(PVA)to obtain PVA/ZnO hydrogel.Subsequently,by using a dip-coating technique,a high-performance filament sensor was constructed by coating the hydrogel onto PET filaments.The results indicated that when the mass fraction of ZnO was 1 wt.%,the PVA/ZnO hydrogel achieved an electrical conductivity of 0.21 S/m and exhibited favorable sensing performance.At a ZnO mass fraction of 8 wt.%,the PVA/ZnO/PET filament sensor demonstrated a frac-ture strength of 169 MPa,along with an electrical conductivity of 3.18 S/m.Under minor deformation conditions,the sensor showed a sensitivity of up to 2.49 with excellent linearity and rapid response capability(<75 ms).Moreover,it effectively monitored motion signals from different parts of the human body and enabled spatial distri-bution recognition of pressure through array integration,demonstrating broad application prospects in the field of wearable health monitoring.关键词
