ABSORBENT AND FLEXIBLE CONDUCTIVE NANOCOMPOSITES FOR BIOELECTRONIC APPLICATIONS

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.
