I’m looking to create a battery powered sealed sensor device. Battery recharge would be via inductive coils. Is it possible to use the wireless power transfer as a data transfer link simultaneously?
Transmitting data from the charger is fairly easy, but signalling back from the load less so, although you might be able to do so by changing the effective load impedance between two states. Back in the 90s I worked on a system that used inductive charging and then had an infra-red link for data transfer, which worked very well.
