....it's called 'using batteries'
With this form of wireless power, you don't have to remember to replace the batteries, and you don't have to interrupt the device from working while the batteries are being replaced.
....With wireless power, would each device need some kind of special wireless receiver/transformer?
Yes, just like wireless phones, which each need a special wireless receiver/transformer.
