Harvesting Energy From The — Air: Surface-based Antennas Primarily Convert Ambient Radio Waves Into Electrical Energy
This title clearly highlights surface-based technology for harvesting low-power ambient radio frequency (RF) energy, making it an engaging choice for a technical review. To enhance the review, focus on the specific type of antenna (e.g., rectennas, metasurfaces), the power conversion efficiency (PCE), and the practical applications, such as IoT sensors or smart city infrastructure.
