A 3-D RFID/NFC Cylindrical Magnetic Reader Coils Structure, 3DCCS, for Orientation-Free Detection of HF Tags, for Biomedical Applications

Near Field Communication (NFC) technology has been explored in the application field of biomedical sciences. NFC’s inherent capabilities, such as battery-less short-range communication and secure data transfer, make it an ideal candidate for various biomedical monitoring applications. In healthcare, NFC facilitates patient identification, access control, and secure data transmission between medical devices. Additionally, NFC-enabled smart wearable devices enhance real-time health sensors data collection. A novel NFC 3D cylinder reader coil structure applied in the realm of biomedical sciences is introduced in this paper. The newly designed coil structure generates a planar rotating magnetic field, significantly improving the likelihood of successful tag identification. This enhancement in the coils’ magnetic field distribution facilitates efficient communication between NFC tags and the reader. CST simulation for the generated magnetic field has been done for design optimization. A tube with overlapped copper tape is built for experimental tag detection validation. The 3D cylinder reader coil structure enhances communication in healthcare systems.
