Keywords:
Graphene, Hydrogel, Bioelectronics, Biosensors, Composites, Neural Interfaces, Wearable DevicesAbstract
Graphene-enhanced hydrogel composites are attracting significant attention as multifunctional materials for bioelectronic interfaces. By combining the superior electrical conductivity, mechanical strength, and large surface area of graphene with the hydrated, soft, and biocompatible properties of hydrogels, these composites enable seamless integration between biological tissues and electronic devices. Such materials have shown promise in neural recording, wearable biosensors, and implantable therapeutic devices.
The synergistic characteristics of graphene-hydrogel systems address critical challenges in conventional sensor interfaces, such as poor signal fidelity, mechanical mismatch, and limited long-term stability. Their tunable properties allow for high sensitivity, flexibility, and adaptability across medical diagnostics, environmental monitoring, and regenerative engineering. This article reviews fundamental properties, fabrication techniques, applications, and future perspectives of these composites.
