NFC technology is widely available on mobile phones, making it a practical choice for users. NFC energy harvesting can provide the necessary milliwatt range of power needed to ensure serviceability. Infineon ✪ s latest solution for NFC locks can harvest 20 to 50 mW from the NFC field, depending on the type of mobile phone in use.
When a mobile phone with an active NFC is put close to the NFC antenna of the smart lock, the mobile phone will detect the NFC device and start to build an NFC communication (see Figure 1). Spontaneously, the 13.56 MHz NFC carrier signal transfers a certain amount of energy to the receiver antenna.
Spontaneously, the 13.56 MHz NFC carrier signal transfers a certain amount of energy to the receiver antenna. The received AC signal is converted to DC current by the rectifier and used to charge the capacitor. As long as the NFC connection is available, energy is transferred from the mobile phone to the capacitor.
For an NFC IC equipped with energy harvesting, the main limitation is the WPT in the uplink because it is necessary to provide higher energy than in a conventional NFC IC without energy harvesting. Thus, the read range in NFC tags with the EH mode activated is lower than the range for reading a previously stored data in the memory.
It is composed of an antenna that receives the interrogation signal emitted from a reader, usually, a mobile equipped with an NFC reader, an NFC integrated circuit, a microcontroller, and the sensor and its conditioning electronics. Table 2 shows that there are several commercial NFC ICs with energy-harvesting capabilities available in the market.
After reviewing power transfer in NFC, recommendations for the practical design of NFC-based sensor tags and NFC readers are made. A list of commercial NFC integrated circuits with energy-harvesting capabilities is also provided.
