Problems solved by technology

However cracks in the tubes may interrupt the wiring or alter the conductivity so they cannot conduct electrical power
Also, for applications that require power transmission along long conduits, the solution is costly as the wiring may stretch across the entire length of the conduit

Abstract

A capacitive powering system constructed to enable wireless power transfers inside a tube-shaped structure (200) includes a capacitive tube (220) including a pair of receiver electrodes (223, 224) connected to a load (221) through a first inductor (222), wherein the first inductor is coupled to the load to resonate the system; a transmitter device (210) including a pair of transmitter electrodes (213, 214) connected to a power driver(211); and an insulating layer (230) for electrically insulating the capacitive tube from the transmitter device to form a capacitive impedance between the pair of transmitter electrodes and the pair of receiver electrodes, wherein a power signal generated by the power driver is wirelessly transferred from the pair of transmitter electrodes to the pair of receiver electrodes to power the load when a frequency of the power signal substantially matches a series-resonance frequency of the first inductor and the capacitive impedance.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 61 / 523,919, filed August 16, 2011, and U.S. Provisional Application No. 61 / 622,103, filed April 10, 2012. technical field [0002] The present invention relates generally to capacitive powering systems for wireless power transfer and more particularly to structures for allowing efficient power transfer in tubular structures. Background technique [0003] Wireless power transfer refers to electric power supply without any wiring or contact, and thus power supply to electronic devices is performed through a wireless medium. One popular application for contactless power supply is for charging portable electronic devices such as mobile phones, laptop computers, and the like. [0004] One implementation for wireless power transfer is through an inductive powering system. In such systems, electromagnetic inductance between a power source (transmitter) and a device (receiver) allows contactless power tr...
