Wireless Power Transmission


Wireless Power Transmission

$1 MILLION (Prize amount to be confirmed. Announcement expected for next year)

Wireless power transmission, is the transmission of electrical energy without wires as a physical link.

In a wireless power transmission system, a transmitter device, driven by electric power from a power source, generates a time-varying electromagnetic field, which transmits power across space to a receiver device, which extracts power from the field and supplies it to an electrical load. The technology of wireless power transmission can eliminate the use of the wires and batteries, thus increasing the mobility, convenience, and safety of an electronic device for all users.

Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible.

Wireless power techniques mainly fall into two categories, near field and far-field.

In near field or non-radiative techniques, power is transferred over short distances by magnetic fields using inductive coupling between coils of wire, or by electric fields using capacitive coupling between metal electrodes. Inductive coupling is the most widely used wireless technology In far-field or radiative techniques, also called power beaming, power is transferred by beams of electromagnetic radiation, like microwaves or laser beams.

While this technology is still at the beginning it can be considered extremely promising and with the possibility to deliver huge amounts of benefits for its users and the society in general by eliminating wires, cables and many other equipment associated with power transmission.

Wireless Power Transmission

The solution can include:

This competition calls for advanced concepts of wireless power rasnnisssion of both types, near field and far field, with new equipment, new capabilities , the demonstration of a wireless house powered by independent solar sources.


This is a two phase competition:

  • Phase 1 :written proposals, (max 40 pages including images) about the technologies and systems that would be utilized will select the five finalist that would proceed to phase 2;
  • Phase 2: to realize the required experiment under controlled conditions.
