Near Field Magnetic Induction (NFMI) technology offers a new solution to hand hygiene monitoring. NFMI technology provides proximity detection on the centimeter level, making it highly accurate as a device worn on the person. The centimeter-level detection is also configurable which allows it to mim...
A near-field low-power communication device with an electrically small antenna for low-frequency UWCNs is proposed in this study. The device can be easily buried underground. The proposed device is analyzed in terms of basic communication metrics, i.e., magnetic field intensity, bandwidth, path...
1Is NFC the same as Near Field Magnetic Induction (NFMI)? Theoretically, yes; however, NFMI is being used as a marketing term for a specific set of NFC that increases the range. In this learning module, we will refrain from using that terminology. ...
