It uses kinetic energy to send a wifi signal to the base.
You were doing well until this point.
That's what it does. No battery no wires.

So what you are now saying is it uses mechanical energy to generate a
wireless signal.
Designing a nano-scale 433MHz dynamotor might be an interesting exercise
for a graduate student, but hard to modulate. I am imagining a special
cam. But I suspect they convert the force to electrical power first,
perhaps piezoelectric?
Apologies. I mean an RF alternator, not a dynamotor.
