Development of Flexible, Conductive and Biocompatible Chitosan-Based Miniaturized Bioelectrodes for Enzymatic Glucose Biofuel Cells

The need for new clean energy sources portable devices in biomedical, agro-food industry and environmental related sectors boosts scientists towards the development of strategies harvesting their application biodevices development. In this sense, enzymatic biofuel cells (BFCs) have gained much attention last years. This work faces challenge develop generation BFCs able to be adapted remote personal monitoring within framework wearable technologies. To aim, one main challenges consists conductive biocompatible electrodes, which constitute a itself due non-conductive capabilities most supports. Additionally, bioelectrodes may achieve good mechanical properties resilience order suitable envisioned application, involves exposure deformation during long-term use. Furthermore, it is desirable that systems developed are versatile enough miniaturized supports present work, self-standing chitosan-carbon black membranes been synthesized modified with enzymes assembly an glucose BFC. integrated interdigitated gold electrodes as step forward systems, metallic particles clusters tested from solutions. system produces power density 0.64 µW/cm2 enhanced 2.75 presence clusters, 76% incensement. Such preliminary demonstrations highlight response metals bioelectrode configuration. However, real still improvements but pave way use BFC source technologies mechanical, electrical properties.
