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.

This paper presents a novel circularly polarized rectenna designed for efficient electromagnetic energy harvesting at the 2.45 GHz ISM band. A compact antenna structure is designed to achieve high performance in terms of radiation efficiency, axial ratio, directivity, effective area, and harmonic rejection over the entire bandwidth of the ISM frequency band. The optimized rectifier circuit enhances the RF harvested energy efficiency, with an AC-to-DC conversion efficiency ranging from 36% to 70% for low-level input power ranging from −10 dBm to 0 dBm. The stable output of DC power confirms the suitability of this design for various practical applications, including wireless sensor networks, energy harvesting power supplies, medical implants, and environmental monitoring systems. Experimental validation, which includes both the reflection coefficient and radiation patterns of the designed antenna, confirms the accuracy of the simulation. The study found that the proposed energy harvesting system has a high total efficiency ranging from 53% to 63% and is well-suited for low-power energy harvesting (0 dBm) from ambient electromagnetic radiation. The proposed circularly polarized rectenna is a competitive option for efficient electromagnetic energy harvesting, both as a standalone unit and in an array, due to its high performance, feasibility, and versatility in meeting various energy harvesting requirements. This makes it a promising and cost-effective solution for various wireless communication applications, offering great potential for efficient energy harvesting from ambient electromagnetic radiation.

“…Different energy harvesting (EH) methods are being researched to enhance the battery lifespan of the sensor nodes. A wireless power transfer (WPT) technique has emerged as the most popular choice [2], [3] as it provides easy integration with the existing communication circuitry. Moreover, sensor nodes collect information related to the surrounding environment and communicate it with a remote gateway through an in-housed wireless information transfer (WIT) antenna.…”

An integrated, miniature, dual-purpose circular patch antenna is proposed for Simultaneous Wireless Information and Power Transmission (SWIPT). The design proposes a proximity-coupled feed to the radiative circular patch for Wireless Information Transfer (WIT) in 5.7 GHz -6.0 GHz band and an integrated capacitive-coupled feeding network, with full-wave rectification (FWR) using regenerative opposite fringing fields from the radiating edges of the patch for energizing IoT sensors by means of wireless power transfer (WPT) at 5.2 GHz. For the realization, two co-polarized fringing field harvesters are capacitively coupled to the radiating edges of the patch to regenerate those opposite fringes whose currents are effectively matched to the FWR using a pair of Schottky diodes for direct current (DC) power generation. Since the gain and efficiency of the patch, in WIT mode, are favoured when using the FWR network, the effective regenerative fields, which are deemed attractive in modern wireless sensor network (WSN) applications for boosting the lifespan of sensor nodes.
