The receiver efficiency in radio-frequency (RF) energy harvesting (EH) is affected by numerous parameters such as the average RF input power and peak-to-average power ratio (PAPR) of the waveform, the EH circuit components, and the load. In this paper, we experimentally study the dependence of RF-to-DC efficiency on these parameters. We present a test-bed, comprising a signal generator and an off-the-shelf energy harvesting receiver with a diode-based rectifier, for evaluating the RF-to-DC efficiency for varying input RF power, load resistance and a number of co-phased baseband multisine waveforms (viz. PAPR). The experimental results suggest that the RF-to-DC efficiency of multisine waveforms in RF EH is significantly affected by the average input RF power and the load resistance. The high-PAPR multisine waveforms are preferable for RF EH only for a certain range of average input RF power and load resistance. In particular, for the considered rectifier, a single-sinusoid waveform yields the highest RF-to-DC efficiency for low-resistance and high average input RF power region, while high-PAPR baseband multisines are optimal for high-resistance and low average input RF power region.

Unlike other wireless power transfer methods that use electromagnetic waves, acoustic vibrational waves can be used to transfer power through metal structures without being shielded, which is useful for applications such as pipeline structural health monitoring, wireless sensor networks, and UAV recharging platforms. In this paper, we demonstrate, for the first time, the unique ability of acoustic power transfer to selectively charge receivers attached at different locations on a metal structure by exciting different Lamb wave vibration modes using a transmitter array. Efficiency ratios (efficiency of the targeted receiver divided by the efficiency of the untargeted receiver) as high as 55000 could be achieved, with 33% efficiency achieved at 28 kHz when transferred along a 30 inch steel tube. Finite element modeling was also used to visualize the standing wave vibration modes.

In this study, we aim to realize SWIPT (Simultaneous Wireless Information and Power Transfer) at the same frequency using the OAM (Orbital Angular Momentum) mode. To investigate which OAM mode is desirable for WPT (Wireless Power Transmission) and how much isolation can be realized, we studied how the power transmission efficiency and the mode isolation was changed depending on the transmission distance in the simulation. We have revealed that the mode 0 is desirable for WPT and the high isolation can be realized using the OAM mode.

This paper proposes a three-layers stack metasurface first, and then employed it to a compact double-band wireless power transfer (WPT) system. For the proposed dual-band WPT system, the metasurface exhibits the wide-band characteristic of the negative-near-zero permeability from 222 MHz to 889 MHz, where the transmission efficiency improves significantly at longer WPT distance at the lower band. Only a unit cell is stacked in three layers so that the size of the proposed metasurface has significantly reduced compared to a conventional metasurface where several unit cells are arranged in 1-D topology. The size of the proposed WPT system and the metasurface is 15 x15 mm and 20 x20 mm, respectively. Also, capacitors with the value of 0.1pF are etched on the gaps of the metasurface. The measured efficiencies’ improvement ratios are 1.13 at 390 MHz in the air, where the WPT distance is significantly improved from 19 mm to 23 mm.

28 GHz microwave power transmission to free-flight drone experiment was conducted in a 10 m anechoic chamber. An AR-drone were controlled by IFT algorithm with indoor GPS. We developed a 50 % maximum efficiency rectifier and single-axis beam forming system. We demonstrated microwave power transmission with these systems for the flying drone at an altitude 800 mm. Phased array antenna consisted of 2 horn antennas transmitted 3.9 W in total. As a result, rectennas attached on the drone were able to continuously receive power for about 20 seconds, and the maximum overall efficiency was 0.044 %.

Most of the next-generation implantable medical devices that are targeting sub-mm scale form factors are entirely powered wirelessly. The most commonly used form of wireless power transfer for ultra-small receivers is inductive coupling and has been so for many decades. This might change with the advent of novel microfabricated magnetoelectric (ME) antennas which are showing great potential as high-frequency wireless powered receivers. In this paper, we compare these two wireless power delivery methods using receivers that operate at 2.52 GHz with a surface area of 0.043 mm2. Measurement results show that the maximum achievable power transfer of a ME antenna outperforms that of an on-silicon coil by approximately 7 times for a Tx-Rx distance of 2.16 and 3.3 times for a Tx-Rx distance of 0.76 cm.

This paper presents a tunable multistage matching network (TMMN) for compensating variations in large air-gap capacitive wireless power transfer (WPT). The proposed multistage matching network is employed with a variable capacitor, whose capacitance value is suitably modified to compensate for misalignments and distance variations between couplers. This capacitor is connected at an intermediate port of the multistage matching network, allowing it to be realized using devices rated for a much lower voltage than the coupler voltage, which is rated at kilo-volt level for large air gap capacitive WPT system. A systematic methodology to design the proposed TMMN which maximizes its compensation range while maintaining low losses is also introduced. A 27.12-MHz prototype is designed, built and tested to validate the concept and design methodology.

This paper reports 400-W 85-kHz band inductive charging system prototype for UAV or drone to be employed for overhead power transmission line patrol. For patrol of the long overhead power transmission line network, the consecutive charging opportunities which will be provided by multiple rapid wireless charging ports are desired. The rapid inductive charging system with frustum-shape wireless charging port and lightweight on-board power receive equipment is prototyped to serve such opportunity charging. The successful test of sequential operation of landing on the wireless charging port, 400-W or more wireless charging of lithium ion battery, taking off, and photo-shooting of overhead power transmission lines between actual high-rise steel towers by high-precision camera, show a great potential of the proposed inductive charging system for opportunity charging of long range patrol.
