Absorbent and Flexible Conductive Nanocomposites for Bioelectronic Applications

摘要

The development of flexible electrodes has garnered heightened interest by the wearables community for monitoring and treating human health and performance in a non-invasive and unobtrusive manner. There remains a gap in developing absorbent, biocompatible, flexible, and scalable electrodes for wearable applications. To address this shortcoming, we developed a carbon black-polyvinyl alcohol (CB-PVA) nanocomposite electrode. Glycerol was used to facilitate hydrogen bonding and crosslink the nanocomposite. The material provides high flexibility, electrical conductivity, and demonstrates electrical stability over a long-term duration (5 hours). This simple and cost-effective fabrication method for CB-PVA nanocomposites provides an opportune pathway for various applications in the bioelectronics field.
