The implantation of devices and prostheses is considerably rising in recent years. When an implanted medical prosthesis is equipped with a local wireless sensor, an early-onset identification of possible infections could be achieved. This paper proposes a method to transform a metallic dental implant into an antenna integrating a temperature UHF RFID sensor. A sensorized add-on disk, fully embedded in the dental implant’s crown, collects the external interrogating electromagnetic field and transforms the implant itself into a top-excited dipole. After simulations, a preliminary prototype of the resulting Cyber-Tooth is experimented with a near-filed interrogation by means of an on-cheek antenna. Results are promising for the establishment of a robust backscattering link, as a good margin in the link budget is achievable with further improvements in the tuning of the disk harvester.

In this paper we demonstrate the possibility to use a mobile RFID reader to monitor the motion of visitors in a museum. The embedded system composed of an RFID reader, a 10-axis inertial management unit and a logger allows indoor localization based on the detection of multiple passive tags located at known geographical positions along the tour of the visitor. The design of the proposed RFID based system to localize persons in indoor environment is validated by simulations and practical measurements in a museum.

Ambient backscatter communication (AmBC) systems utilize existing ambient radio frequency (RF) signals to establish an indirect communication link between a transmitter (TX) and a receiver (RX). Backscatter devices (BDs) modulate their useful information on the incoming ambient signal emitted by the TX, as such their range is usually a very short event when only one BD is considered. This paper aims to analyze the impact of the interference generated due to the presence of another BD in a bi-static backscatter communication system. It is observed from the simulation results that the received signal degradation is mostly due to the cross interference of the other BD, which can be mitigated using successive interference cancellation (SIC) techniques. The level of both cross interference and self interference is significant when the interfering BD is located close to the target BD or the receiver. Therefore, AmBC systems can support more than one BD in an environment as long as the BDs are placed more than a wavelength apart from each other and RX.

This paper describes a smart system based on the Radio Frequency Identification Technology (RFID) and conceived within the SENERGY Project for worker safety applications. An RFID tracking system allows to monitor the worker position during the maintenance activities on machinery assemblies, thanks to a synthetic-array approach. The reader antenna moves above the machinery assembly area through a 3D-axis cartesian portal. The worker equipped with several passive UHF-RFID tags is tracked in real-time with errors comparable with body sizes, thus improving the safety and health requirements of the system.

Radio tomographic imaging (RTI) is one of potential device-free localization (DFL) technologies. Solving RTI model is an ill-posed problem that the number of measurements is less than pixels in a reconstruction image. Currently, the Tikhonov regularization based least square method (TRLS) is used to handle the problem, but its artificial regularization parameter disturbs initial RTI model and results in low localization accuracy. Gradient iteration regularization method (GIRM) is proposed to solve RTI model and has the advantages of high accuracy, low storage cost, good convergence and high stability. Unlike the TRLS, it uses mathematical deviation to obtain its parameter required for the solution and adopts several iterations to further weaken the influence of the parameter on the model. The image processing eliminates false targets and artifacts in a reconstruction image to obtain the number and the locations of real targets. Simulation shows that the localization performance of proposed method is higher than TRLS.

In this paper, we propose a safety alert system based on LoRa(Long Range) communication, where the communication takes place in the range of kilometers. Because of the long-range, the low power consumption, and the long battery, our proposed system can continuously operate without disruption. In India, It is recorded that average of 87 rape cases daily in 2019 and overall 4,05,861 cases of crime against women during the year, a rise of over 7% from 2018, the latest government data released on September 29, 2020[1]. These statistics show how weak we are in terms of the safety of women in India. So to reduce crime against women, our proposed prototype will give the long-range alert signal along with the GPS location with a single push of a button.

Near field communication (NFC) is a subcategory of Radio frequency identification (RFID) that is completely vital as a part of 5G and IoT. The Device-to-Device (D2D) communique, Vehicle-to-Vehicle (V2V) communique, Machine-to-Machine (M2M) communique, and Internet-of-Things (IoT) are the modern-day techniques, which contributes an essential function in present wireless and mobile communique. But the primary hassle for the cutting edge wireless communique system is the ‘steering withinside the layout of ultra-low latency’. Ultra-low latency wireless transmission makes use of asynchronous transmission. Universal Filter Multi-Carrier (UFMC) is a brand new modulation method alongside an advanced filtering wireless mechanism that overcomes this hassle. This paper is provided that the increment withinside the range of sub-bands complements the Bit Error Rate (BER) for UFMC. Here efforts are furnished for the discount withinside the BER through growing SNR.

In this paper, we introduce the new concept of Crowd-Detectable Zero-Energy-Devices. Such devices harvest solar or ambient light energy to power themselves, backscatter ambient waves to communicate, and are detected simultaneously by a smartphone connected to the network, and the network itself, as long as the device is close to the considered smartphone. Such device is a promising sustainable solution for the future of the Internet of Things. We describe an example of use case: asset tracking with zero added energy, zero new signals and zero new infrastructure in the network, thanks to the anonymous and transparent participation of smartphones connected to the wireless network. We then present our first prototypes of such devices that backscatter TV, 4G and 5G signals, and show our first experiments in challenging conditions and environments.

Forced ripening through the exposure of fruits to controlled environmental and gases conditions is nowadays one of the most assessed food technologies especially for climacteric and exotic products. However, a fine granularity control of the ripening process and consequently of the goods quality is still missing, so that the management of the ripening room is mainly based on qualitative estimations only. Following the modern paradigms of Industry 4.0, this contribution proposes a nondestructive RFID-based system for the automatic evaluation of the live ripening of up to 128 avocados inside the ripening room. The system, coupled with a properly trained automatic classification algorithm, is capable to discriminate the early stage of ripening with an accuracy greater than 85%.

This paper is based on an experimental setup for RFID tag characterization using an Alien 9900+reader. The first part uses a technique based on the joint acquisition of the tag response versus transmitted power and distance for determining the RSSI (Received Signal Strength Indicator) conversion toward the received power. The second part presents an experiment which illustrates the effect of absorbing panels on the read range. Observations showed that having no absorbing panels improves the read range of the tag. Multipath have been observed being beneficial for the read range.
