AI Technical Summary
Existing sweat monitoring biosensors suffer functional impairments due to external environmental factors, resulting in insufficient sensitivity and stability. Furthermore, their performance fluctuates significantly in variable environments, making them difficult to integrate with flexible textiles and causing discomfort when worn.
A modified ion-selective film was prepared using a flexible substrate and a modified solution containing hydrophobic substances and fast ion diffusion nanomaterials to enhance the adhesion between the PEDOT:PSS polymer layer and the modified ion-selective film, thereby improving the sensitivity and stability of the biosensor.
The sensitivity and stability of the biosensor have been enhanced, its resistance to washing and mechanical damage has been improved, and its wearing comfort has been increased, making it suitable for monitoring needs under varying environmental conditions.
