I have a question regarding wireless charging. Traditionally, you have two coils, the charger and the receiver for wireless charging with Qi (from what I understand).
Would you be able to have an additional coil in between the two and extend the range from charger to receiver by a few millimeters? I'm very unsure of the science here, so I thought I'd ask here.
Here's a really garbage diagram of what I'm thinking: https://imgur.com/a/ncjwxyh
