Journal ArticleDOI
Analysis of vital signs monitoring using an ir-uwb radar
TL;DR: An analytical model is developed to perform and interpret the spectral analysis of vital signs from the spectrum of recorded waveforms, using an impulse-radio (IR) UWB radar, and a canceler to cancel out breathing harmonics is proposed to improve heart rate detection.
Journal ArticleDOI

TL;DR: This study presents a simplified two-layer emission model for foam-covered water and the results of a controlled experiment to measure the foam emissivity as a function of salinity, foam thickness, incidence angle, and polarization.
Journal ArticleDOI
A Survey of NFC Sensors Based on Energy Harvesting for IoT Applications
TL;DR: An overview of recent advances in the field of battery-less near-field communication (NFC) sensors is provided, along with a brief comparison of other short-range radio-frequency identification technologies, and recommendations are made for the practical design of NFC-based tags and NFC readers.
Journal ArticleDOI
Effects of interferences in uhf rfid systems
TL;DR: In this paper, RFID reader-to-reader interference is analyzed and a model to estimate the minimum distance between readers to achieve a desired probability of detection in real multipath environments is derived and compared to the ideal case (AWGN channel).
Journal ArticleDOI
Time-Domain Measurement of Time-Coded UWB Chipless RFID Tags
TL;DR: Two difierent setups to detect time-coded UWB chipless tags for RFID in time domain are presented and the experimental results show the feasibility of using an IR-UWB radar as a UWB RFID reader, achieving very good read ranges.
