I'll try to make bluetooth headset to support Wireless charging. As know, because of limited space inner headset, the size of coil is very important.
1. Is it possible to evaluate with FPCB type coil for low profile at the rate of 100mAh , 5V?
2. How can be estimated the coil specification ( width/length / coil diameter) vs rated current?
Yes a PCB coil or Flex PCB coil is possible and we are evaluating some designs.
I will contact you using the Conversation feature for more information on your application.
