“…[ 43 ] Radiofrequency energy harvesting (RF EH) is the technique of harvesting power from ambient electromagnetic (EM) radiation sources in radio frequency (between 3 kHz and 300 GHz) available freely in the device deployment environment, utilizing a rectifying antenna (Figure 1e). [ 13 ] EM radiation sources above the RF spectrum—infrared and visible light, up to 700 THz [ 44 ] —can also be harvested using nanometer‐size rectifying antennas. However, practical implementation is limited by either unsatisfying diode integration for the rectification step to happen at terahertz frequencies in a top‐down approach (e.g., nanolithography methods) or difficult collection of the rectified charges (e.g., molecular diodes with nanoparticles patch antennas).…”

The Internet of Things is currently one of the fastest-growing branches in electronics. The development of energy storage systems and the miniaturization of dedicated printed circuit boards significantly influence that growth. However, the need for batteries and traditional printed circuit boards still limits devices' minimum size, weight, and cost, narrowing the application area. Energy harvesters and wireless power transfer systems fabricated with printed electronics can significantly reduce such devices' weight, size, and cost. Printed electronics technology provides scalable tools for many electronics applications, shortening the validation time and enabling new low-cost or disposable solutions on lightweight and flexible substrates embedded inside 3D printed structures and directly on device housings. Energy harvesting and wireless power transfer systems in electronic devices can provide enough power to minimize battery capacity and size or even eliminate the need for batteries in low-power applications. This review presents an adaptation of printed electronics technology in the fabrication of radio frequency energy harvesters and wireless power transfer rectennas for IoT applications. Last, perspectives for development towards greater integration with microsystems, transient electronics with ecofriendly materials, adaptation for next-generation telecommunication systems, and 3D structural electronics solutions are briefly discussed.

Metal–insulator–metal (MIM) diodes facilitate rectification at high frequencies. However, the rectification ratio for light from visible to infrared spectra is insufficient. In this study, we developed a MIM diode with a strongly enhanced electric field achieved using the self-assembly of Pt nanoparticles (NPs) via atomic layer deposition. By shaping the tunneling barrier, current density and asymmetry were simultaneously enhanced by several orders of magnitude compared with the symmetric MIM diode. The diode efficiency of the proposed MIM diodes was experimentally demonstrated to be 231 times greater than that of the MIM diode without NPs. This strategy indicates significant potential for high-frequency rectification applicable in optical rectenna.

In this work, we introduce a solar rectenna that is combined with a periodic subwavelength spiral antenna and a metal-oxide-semiconductor photon-assisted tunneling diode. We obtain spectral absorption and electromagnetic field distributions by numerical simulations and calculate the tunneling current densities generated by solar rectenna. The results indicate that broadband absorption with a peak value over 0.99 is achieved in the range of 400-2500 nm. Additionally, the figure of merit for tunneling electric field enhancement reaches over 104. Under AM1.5 solar irradiation, the calculated zero-bias tunneling current densities are up to 13.93 mA/cm2. This study is expected to advance the development of ultra-high frequency rectennas and pave the way for efficient solar energy harvesting.
