Long-Range Optical Wireless Information and Power Transfer

Optical wireless communications with optical power and dynamic range constraints

Long range inductive power transfer system

We report upon a recently developed long range inductive power transfer system (IPT) designed to power remote sensors with mW level power consumption at distances up to 7 m. In this paper an inductive link is established between a large planar (1 x 1 m) transmit coil (Tx) and a small planer (170 x 170 mm) receiver coil (Rx), demonstrating the viability of highly asymmetrical coil configurations...

Magnetic Metamaterial Superlens for Increased Range Wireless Power Transfer

The ability to wirelessly power electrical devices is becoming of greater urgency as a component of energy conservation and sustainability efforts. Due to health and safety concerns, most wireless power transfer (WPT) schemes utilize very low frequency, quasi-static, magnetic fields; power transfer occurs via magneto-inductive (MI) coupling between conducting loops serving as transmitter and re...

Receiver Antenna Partitioning for Simultaneous Wireless Information and Power Transfer

Powering mobiles using microwave power transfer (PT) avoids the inconvenience of battery recharging by cables and ensures uninterrupted mobile operation. The integration of PT and information transfer (IT) allows wireless PT to be realized by building on the existing infrastructure for IT and also leads to compact mobile designs. As a result, simultaneous wireless information and power transfer...

UAV-assisted Cooperative Communications with Wireless Information and Power Transfer

In this paper, we focus on a typical cooperative communication system with one pair of source and destination, where a unmanned aerial vehicle (UAV) flying from a start location to an end location serves as a mobile relay. To efficiently utilize energy in ambient environment, the UAV’s transmission capability is powered exclusively by radio signal transmitted from the source via the power-split...
