“…Harvesting technologies of environmental energy, such as solar, thermal, wind, and RF energy [1][2][3][4], may become a valuable solution for the power supply to low-power electronic devices. RF energy, as one of the environmental energy sources, has been extensively studied in the context of energy harvesting due to its ubiquity in radio broadcasts, base stations, and Wi-Fi signals [5][6][7][8][9][10][11][12][13][14]. A thermoelectric generator (TEG) is a solid-state component that directly converts thermal energy into electricity and is also attracting attention as an independent, clean, renewable energy source.…”

This manuscript proposes a hybrid energy harvest and management system to manage harvested ambient thermal and radio frequency (RF) energy and provide constant voltage for an electronic water meter. It mainly includes an antenna, a rectifier, thermoelectric generators (TEGs), and an energy management circuit. The antenna harvests the ambient RF power, and the rectifier converts it to DC power. The harvested RF and thermal powers are stored in a capacitor and managed by an FEH710 energy management circuit to power an electronic water meter. Eight thermoelectric generators convert thermal energy into DC power. The proposed hybrid energy harvesting and management system has been evaluated by simulation and measurement. The antenna's reflection coefficient and peak gain at 2.45 GHz are −30 dB and 3.6 dBi, respectively. The rectifier's measured RF-DC power conversion efficiency (PCE) is 66.7% at 0 dBm. As a demonstration, a commercial electronic water meter works stably by the harvested ambient RF and thermal energy. The proposed hybrid energy harvesting system is expected to find potential practical applications for the Internet of Things (IoT) in environments with RF radiation coverage and temperature gradients.

The proliferation of Internet of Things (IoT) devices has led to an increasing demand for efficient and sustainable energy sources to power these autonomous systems. Radio Frequency (RF) energy harvesting has emerged as a promising solution, capitalizing on the omnipresent RF signals in our environment. This article presents the design and analysis of a Dual-Port Multiband RF-to-DC Converter using a multi-stage Cockcroft Walton Voltage Multiplier (CWVM) topology, which is tailored to meet the specific needs of IoT energy harvesting applications. Impedance matching is achieved by the implementation of L-network and π-network using distributed elements. The proposed design enables simultaneous energy harvesting across six bands from 0.87 to 2.5 GHz. It exhibits peak efficiency of 66% and 62% at 10kΩ and 18kΩ, respectively. The multiband feature enhances the energy acquisition versatility. The key parameters, including impedance matching, output voltage, and conversion efficiency, are simultaneously analyzed and optimized for all the frequency bands to achieve the desired performance. The proposed design performance is compared with the recent converter designs in literature, which shows that this research contributes to the ongoing development of energy-efficient solutions for IoT devices, addressing the critical need for prolonged autonomy of IoT devices and reduced reliance on traditional power sources.

This paper presents a low-cost antenna integrable to a large set of indoor common building materials. Employing the printing technology on thin transparent polyethylene terephthalate material and using available building materials not only leads to a low-cost environmentally friendly solution for the expected massive sensor deployment but also eliminates the dispersive behavior of the materials that are interacting with them. A coplanar-strips fed fractal folded antenna element was designed and validated experimentally with four different materials including gypsum, plywood, and plexiglass. The aesthetically viable ground-free antenna achieves wideband performance and radiates in the broadside plane perpendicularly to the wall. The single antenna element covers the frequency band of 2.18-3.96 GHz with a gain of 1 dBi at 2.4 GHz. To take advantage of the large available surface, a high efficiency 2.4 GHz array rectenna for powering electronic devices intended for IoE technology is proposed. The proposed array rectenna has a dimension of 384 × 354 × 6.475 mm 3 and employs a single diode as the rectifier element. The measured results for the presented array rectenna reveal an AC-DC powerconversion-efficiency (PCE) of more than 20% for input powers as low as 0.025 µW/cm 2 with a peak PCE of 61.3% at 4.03 µW/cm 2 .
