POWERING DEVICES USING RF ENERGY HARVESTING

摘要

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.

主权项

1. An apparatus, comprising:
an antenna configured to wirelessly receive energy from a source that is remote from the apparatus; a power harvester electrically coupled to the antenna and configured to convert the energy received at the antenna to a DC voltage to produce a first power associated with the DC voltage; a regulator coupled to the power harvester and configured to regulate the first power associated with the DC voltage to produce a regulated power; an alternative power source configured to produce a second power different from the first power and the regulated power; and a radio-frequency identification (RFID) device electrically coupled to the antenna and configured to wirelessly communicate with the source via the antenna, the RFID device electrically coupled to the alternative power source, the power harvester and the regulator, the RFID device including an integrated circuit configured to operate based on at least one of the first power received from the power harvester, the regulated power received from the regulator, or the second power received from the alternative power source.
