Abstract

Recent advancements in the semiconductor integrated circuits and functional materials technologies have accelerated the demand of electronic and biomedical devices such as internet of things (IoT) and wearable sensors, which have low power consumption, miniature size and high data transfer efficiency. Wireless power transfer (WPT) has become the alternative solution to current electronic devices that rely on bulky batteries to supply the power and energy. Near Field Communication (NFC) technology is extensively used for wireless power transfer, where devices communicate through inductive coupling via induced magnetic fields between transmit and receive coils (loop antennas). Thin NFC sheets made of soft magnetic materials are inserted between antennas and metal case of wireless gadgets, such as mobile phones or tablets, to reduce the degradation of antenna gain and radiation efficiency due to generation of eddy currents. To enhance the efficiency of wireless power transfer, magnetic materials with superb properties such as high permeability, low magnetic loss and high resistivity are highly desirable. In this chapter, we will provide an overview of the current state of the art, recent progress and future directions in NFC based wireless power transfer, with the special focus on near field communications operating at 13.56 MHz.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • NFC supports two-way data communication between an external coil or loop antenna and a second implanted coil while penetrating the tissue barrier.

    “Moreover, NFC’s capability to support two-way data communication between an external coil or loop antenna and a second implanted coil, while penetrating the tissue barrier, further sets it apart.”

    From Comparative analysis of energy transfer mechanisms for neural implants (2024) · cites this paper as Lathiya and Wang, 2021

    The Figure 1 discussion describes NFC as supporting peer-to-peer communication and says a tag responds to a reader, supporting two-way data exchange. Section 3 describes coupling between coils, and §7.3 lists NFC applications in implants. The paper does not establish that two-way data communication occurs specifically between an external coil and an implanted coil across a tissue barrier. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • NFC's dual functionality for both power transfer and data exchange at close proximity makes it a versatile choice for neural implant systems.

    “This dual functionality for both power transfer and data exchange at close proximity makes NFC a versatile choice for neural implant systems, serving specific purposes that broader inductive coupling technologies might not fulfill (Stoecklin et al., 2020; Lathiya and Wang, 2021; Van Mulders et al., 2022).”

    From Comparative analysis of energy transfer mechanisms for neural implants (2024) · cites this paper as Lathiya and Wang, 2021

    The Figure 1 passages describe NFC as a short-range technology used for wireless energy and data transmission, and §7.3 lists cochlear and optogenetic implants among its applications. The paper does not establish that NFC meets neural-implant needs that broader inductive-coupling technologies might not fulfill; §3 describes NFC itself as based on inductive coupling. No page numbers are available in our copy. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • NFC devices generate weaker electromagnetic fields compared to broader RF technologies.

    “This specialized design results in NFC devices generating weaker electromagnetic fields compared to broader RF technologies, whose radiation levels vary based on power and application (Stoecklin et al., 2020; Lathiya and Wang, 2021; Van Mulders et al., 2022).”

    From Comparative analysis of energy transfer mechanisms for neural implants (2024) · cites this paper as Lathiya and Wang, 2021

    Section 2 says NFC operates over a much shorter range than RFID, and the Table 6 passage says NFC magnetic flux strength decreases quickly with distance. Neither passage establishes that NFC devices generate weaker electromagnetic fields than broader RF technologies; the comparison of generated field strength is unsupported. No page numbers are available in our copy. (LLM, conf=0.77)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
