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.
While NFC wireless power delivers the convenience of cable-free charging to smaller form factor products and devices, NFC Forum compliant power harvesting allows devices to go a step further by eliminating the need for batteries, resulting in the tremendous potential to drive the development of multiple new offerings.
However, 50mW does provide some access to the market – again, for stationary, low-power devices (e.g. smart locks and sensors). Given those constraints, NuCurrent, in partnership with Infineon Technologies, is working to increase the power capabilities of NFC Power Harvesting, by first maximizing the functionality of the receiving antenna.
Product designers can integrate an NFC Forum Wireless Charging complaint power harvesting chip that does not require a battery or other any other form of power supply. This means that energy could be transferred from something like a mobile phone to the battery-less device which can then be used to power the product for a brief period of time.
A list of commercial NFC integrated circuits with energy-harvesting capabilities is also provided. Finally, a survey of the state of the art in NFC-based sensors is presented, which demonstrates that a wide range of sensors (both chemical and physical) can be used with this technology.
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.
