Conformal and Multi‐Domain Radio Frequency Energy Harvesting System Based on Graphene for Internet of Things Applications

Interdisciplinary Materials, EarlyView.
This study details a multi‐domain graphene assembled film (GAF) based radio frequency (RF) energy harvesting system (GEHS) for Internet of Things (IoT) applications. The GEHS integrates a flexible dual‐band, dual‐polarization, dual‐beam antenna array based on GAF materials with a high‐efficiency rectifier.
