The adoption of stretchable rectenna in RF energy harvesting systems emerges as a promising/sustainable solution. Laser-Induced-Graphene (LIG) is in its infancy stages due to the low conductivity observed in polyimide films, leading to diminished antenna performance. This research suggests the utilization of rubber carbon composition due to its flexibility and improved performance in rectennas. The integration of LIG-rubber materials in rectennas showcases advancements in nanomaterial integration, offering a fundamental solution for sustainable energy harvesting in various applications, including wearables, IoT devices, and flexible electronics.
