Abstract
Disclosed is an apparatus for an application including a core device for the application. The apparatus includes a power (preferably RF energy) harvester connected to the core device to power the core device. Also disclosed is a method for an application. The method includes the steps of converting RF energy into usable energy. There is the step of powering the core device with the usable energy.
