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.
A capacitive powering system constructed to enable wireless power transfers inside a tube-shaped structure, comprising:
The system of clam 2, wherein the each of the receiver electrodes is formed as a thin sheet of aluminum glue to an inside wall of the capacitive tube.
A capacitive powering system constructed to enable wireless power transfers inside a tube-shaped structure (500), comprising:
The system of clam 10, wherein the each of the transmitter electrodes is formed as a thin sheet of aluminum glue to an inside wall of the capacitive tube.
A coupling tube for wireless coupling electric energy from a first section (701) of a capacitive tube to a second section of the capacitive tube, comprises:
