Dual-Mode Energy Harvesting Wireless Power Receiver Apparatus With Self-Reviving Capabilities

A dual-mode wireless power receiver apparatus comprising:

• peak detector circuitry communicatively coupled with one or more antennas and operable to detect presence of a radio frequency (RF) field;
• one or more active energy harvesting components enabled when the RF field is greater than an ambient threshold, the one or more active energy harvesting components operable to:
• receive and process directed wireless power from a wireless power transmission system via one or more paths;
• and
• store the received wireless power in an energy storage device;
• and
• one or more passive energy harvesting components enabled when the RF field is less than the ambient threshold, the one or more passive energy harvesting components operable to harvest and store ambient energy in the energy storage device.

A method for operating a dual-mode wireless power receiver client, the method comprising:

• detecting that a power level of an energy storage device of the dual-mode wireless power receiver client is less than an active power threshold value;
• responsive to the power level being less than the active power threshold value, directing the dual-mode wireless power receiver client to transition to a low-power state;
• in the low-power state, harvesting and storing ambient energy in the energy storage device;
• detecting that the power level of the energy storage device exceeds a wake-up power threshold value;
• and
• responsive to the power level of the energy storage device exceeding the wake-up power threshold value, directing the dual-mode wireless power receiver client to wake-up from the low-power state.
