This paper presents a holistic and authoritative review of the role microwave technologies in enabling new generation wearable devices. A human-centric Internet Things (IoT) covering remote healthcare, distributed sensing, consumer electronics, calls for high-performance devices integrated into clothing, which require interdisciplinary research efforts to emerge. Microwaves, "interconnect" wireless networks, can enable, rather than solely connect, next autonomous, sustainable,...
This article presents a harmonic transponder, designed to minimize the tag sensitivity materials close it. The is based on dual-frequency dual-port patch antenna and frequency doubler. be interrogated by fundamental f0 equal 2.4 GHz it backscatters signal at 2f0=4.8 GHz. realized cardboard, while doubler feedlines are manufactured flexible polylactic acid (PLA) substrate. feed lines electromagnetically coupled through H slot apertures. A complete prototype with an area occupation of 5×10 cm...
This paper presents a slot-fed dual-ports rectangular patch antenna suitable for harmonic transponders to be employed in logistics. The is fed with two orthogonal H-slot apertures. sides of the have their first resonance at ${f}_{0}$ and ${2f}_{0}$, respectively. developed multi-layer layout optimized obtain compact two-piece tag, where microstrip circuit components (frequency doubler, microcontrollers, sensors so forth) apertures can realized on thin laminate (possibly flexible substrate)...
Identifying a gas source in turbulent environments presents significant challenge for critical applications such as environmental monitoring and emergency response. This issue is addressed through an approach that combines distributed IoT smart sensors with algorithm based on Bayesian inference Monte Carlo sampling techniques. Employing probabilistic model of the environment, interprets readings obtained from array static to estimate location source. The performance our methodology evaluated...
This paper presents a novel wireless zero-power temperature sensor. Through the combination of harmonic radio frequency identification (RFID) technology and concept amplitude modulation, it was possible to create transponder, which can therefore also be used for sensing applications. The prototype obtained by combining Schottky-diode doubler with negative coefficient (NTC) thermistor. thermistor controls self-bias point diode, thereby changing backscattered signal reader. Since only impacts...
