Need to transmit power wirelessly from 110VAC electrical outlet in US

I need to have someone design a wireless power RECEIVER that can be powered within 3 to 6 inches of a regular US electrical outlet. The receiver needs to be very small - and I cannot have any additional hardware required to transmit the power from the outlet (the power needs to be able to come from the sides of the outlet without any connections required). The receiver also cannot require any secondary power source, such as a battery. The power receiver needs to put out approx. 5VDC. If you feel you have an idea of what I'm looking for or have any other questions, please let me know.

Let me understand this correctly: you want a power receiver that would draw the power out of the thin air in the vicinity of a 120AV power outlet, which is not supplied by any power transmitter. Is that right? My confusion is due to the fact that a standard power outlet is constructed so as to minimize the energy losses due to electromagnetic radiation. The losses cannot be zero, but they are small indeed. Perhaps you could receive some microwatts of energy without a power transmitter, but certainly not 5 Watt (5VA). If you need to transmit power wirelessly, then you are in a need of a transmitter, no? Am I missing something in your request? Please let me know. Thank you. Oh, just to add, I have a PhD degree in physics and I'm an engineer by trade. I know something about electricity.

There are 3 or four methods for transmitting wireless electricity and what you are looking for can only be done by one method only but need a clear line of sight from transmitter to the receiver. Send me pm if only are okay with that

What you are asking for in terms of size requires more development financing than you propose. Firstly, you need an induction coil to be attached close to wires coming in to the back of the outlet. In fact the outlet location is irrelevant. You just need to be very close to the wires in the wall. You will be relying on secondary induction. To gain the most induction power transfer you have to wrap the coil around existing AC wire. Having something 3"-6" away would significantly diminish the secondary induction making the output possibly unusable unless you had a very large induction coil. The amount of power output you get depends on the size of the induction coil. 5VDC 1 amp will need something in the order of 3" in diameter on a 0.5" former and 2" long. That's a lot of wire and bulky. To get DC power, the step-down transformer and AC-DC electronics will add to the bulk. To properly design and spec your project may take a month with the cost that this amount of effort will entail. Please ignore the money quoted with this bid. I was not able to post a message so this was the only way to get this information to you. Regards Roger Fedyk
