In this paper, we propose a waveform design methodology for ultra high frequency radio frequency identification (UHF RFID) systems based on the quantitative analysis of the backscattered signal. This latter is leveraged to probe the wireless propagation channel, allocate power accordingly to frequency components, and design channel-adaptive multisine signals. UHF RFID system performance is evaluated based on the harvested DC voltage at the output of the rectifying circuit of the RFID tag. To this end, a flexible hybrid simulation model with modular architecture is developed via the ANSYS platform to study UHF RFID system performance. Simulation results show that the designed waveforms provide an improved energetic efficiency especially in highly reflective environments.

In the last several years, wireless Battery Management Systems (BMS) have slowly become a topic of interest from both academia and industry. It came from a necessity derived from the increased production and use in different systems, including electric vehicles. Wireless communication allows for a more flexible and cost-efficient sensor installation in battery packs. However, many wireless technologies, such as those that use the 2.4 GHz frequency band, suffer from interference limitations that need to be addressed. In this paper, we present an alternative approach to communication in BMS that relies on the use of Near Field Communication (NFC) technology for battery sensor readouts. Due to a vital concern over the counterfeited battery pack products, security measures are also considered. To this end, we propose the use of an effective and easy to integrate authentication schema that is supported by dedicated NFC devices. To test the usability of our design, a demonstrator using the targeted devices was implemented and evaluated.

RFID continues to offer exciting possibilities for numerous activities, both of mere application of the technology as well as of advanced research. This paper is focused on the research activities developed in the past couple of years at the University of Salento, where RFID technology has been studied since when the UHF band was licensed.In particular, this paper deals with the sole activities linked to 3D printing in RFID, with evidence of recent advances in the state of the art which have enabled, among the others, themes ranging from fully-3D-printed RFID tags, free-form-factor flexible substrates for platform-tolerant tags, and Dielectric Resonator Antennas (DRAs) for higher frequency RFID-inspired backscattering communication.

The RFID (Radio Frequency Identification) technology is evolving strongly with the emergence of cognitive sensor networks and notably the Internet of Things. A significant indicator of this evolution is that the tags are equipped with new capabilities and functions such as more powerful sensors, actuators, etc. This evolution of the RFID requires more energy consumption, and the continued passive nature of tags could be threated. Indeed, the tag needs more and more energy, and the energy received from the only reader can be insufficient. To address this issue, the proposed concept is to exploit the reflected energy by the tags near to the “target” tag. In this paper, we develop the associated theory for far-field conditions. The theoretical development is illustrated and the impact of the relative position between the tags on the total energy captured by the “target” tag is emphasized.

In this paper, a home-based wireless motion capture monitoring system for graded Range of Motion (ROM) Arc device of shoulder rehabilitation using ultra-high frequency (UHF) radio-frequency identification (RFID) at 920 MHz is proposed to realize self-service rehabilitation from 0 degrees to 180 degrees. This device applies to emerging 5G telemedicine, eliminating the need for manual monitoring. Using an array of 11 passive UHF RFID tag’s, each tag is labeled and represents a 15-degree angle along the arc. The tag’s Received Signal Strength Indicator (RSSI) variations from tag backscattering response are used to determine the degree of the patient’s shoulder motion. An experimental prototype with the user interface is built based on conventional ROM, where the patient’s shoulder motion can be automatically captured for further analysis by a therapist. From the experiment, we determined the degree of the patient’s shoulder motion mapping average 35 dB RSSI variation from -80 dBm (with full hand contact) to -45 dBm (without hand contact) averaged.

This paper presents the design of a fully passive 865MHz to 867MHz UHF RFID to $I^{2}$C Bridge IC with an integrated $I^{2}$C master for external digital sensor communications. To provide energy for external devices operation such as sensors, microcontrollers and memories, a Power Storage Unit (PSU) is directly integrated within the IC with an external capacitor as an energy storage element. Hence for communicating with external devices, the IC requires no additional power management components. Additionally, the on-chip $I^{2}$C master eliminates the need for external microcontroller, thus making the system more energy efficient and well suited for ultra-low power (ULP) sensing applications requiring battery free operation. The results show that this IC dynamically supplies an external non-volatile memory and a multi-sensor with 1.8V output voltage and is capable of handling a dynamic load current of up to 1mA required for multi-sensor readout operation. The memory and the multi-sensor are configured individually for timing and communication, while the sensor data is readout by RFID reader successfully. The chip is fabricated in a standard $0.18 mu mathrm{m}$ SOI CMOS technology and its achieved performance are demonstrated in this paper in combination with a high-performance commercial-of-the-shelf sensor capable of measuring air temperature, humidity, and pressure.
本文设计了一种全无源865MHz至867MHz UHF RFID到$I^{2}$C桥接IC，集成了$I^{2}$C主控电路，用于外部数字传感器通信。为了向外部设备(如传感器、微控制器和存储器)提供能量，电源存储单元(PSU)直接集成在IC内，外部电容器作为能量存储元件。因此，为了与外部设备通信，IC不需要额外的电源管理组件。此外，片上$I^{2}$C主控消除了对外部微控制器的需求，从而使系统更加节能，非常适合需要无电池操作的超低功耗(ULP)传感应用。结果表明，该IC动态提供外部非易失性存储器和1.8V输出电压的多传感器，能够处理多传感器读出操作所需的高达1mA的动态负载电流。存储器和多传感器分别配置定时和通信，传感器数据通过RFID读写器成功读出。该芯片采用标准的$0.18 mu mathm {m}$ SOI CMOS技术制造，并在本文中结合能够测量空气温度，湿度和压力的高性能商用货架传感器展示了其实现的性能。

This paper presents an ultrathin dual-band metasurface which exhibits a linear-to-circular polarization conversion reflection band at the 865MHz UHF-RFID band and a co-polarized transmission band at the 2.45GHz WLAN band. When a linearly polarized UHF-RFID reader antenna is placed in front of the metasurface, the linearly polarized wave of the antenna is converted to a circularly polarized wave after reflection from the metasurface. This reflected circularly polarized wave can be used to detect RFID tags. Once the required information is collected from the tags, the RFID reader can then transmit this information via the 2.45GHz WLAN band through the metasurface. This is possible because of the pass-band of the metasurface at 2.45GHz. The metasurface therefore acts in the reflection mode at 865MHz and in the transmission mode at 2.45GHz. The metasurface has an angular stability of 20° for both TE and TM incidence.

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.

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.
