Ok so lets be honest. I did not expected this thing to work. I was afraid that its resistance is going to be too small that it will over heat. But it actually didn't.

The pcb is dual layer and is 0.13mm thick. Although it only has 70 turns, the thin dielectric will improve the coupling. The flex PCB is made from a polyimide material which is highly resistant to heat, which makes the surface barely hot.

In the video I am driving with a 5V voltage supply and it is drawing around 600mA.
