Proof of Concept: Capacitive Plate Wireless Power


Plates can be very cheap (or even be free) to integrate into a design. Any conductive material in any shape can be a capacitor plate- its location is what makes it a plate.

The electric field generated between the plates is mostly canceled out behind them, so the plates act as their own shields.
