Self sustained system with nfc chargeable battery

Abstract

A receiver to wireless communicate data via a magnetic field with a communicator and harvest energy from the magnetic field in the RFID frequency area to load a battery of the receiver. The receiver incudes a first antenna connected to a communication circuit receiving a communicator data signal from the communicator via the magnetic field and processing received communicator data and generating receiver data and built to transmit a receiver data signal via the magnetic field to the communicator. The receiver further includes a second antenna connected to a wireless power circuit built to harvest energy from the magnetic field and to charge the battery of the receiver. The communication circuit and the wireless power circuit of the receiver communicate data and harvest energy to charge the battery in parallel and at the same time via their fixed connected first antenna and second antenna exposed to the same magnetic field.
