The topic presented in this paper is a self-generating PiezoMUMPs integrated sensor for inertial measurements. In particular authors have conceived a suitable design based on a meander structure in order to realize a MEMS device having the following prerogatives: 1) the adoption of an Aluminum Nitride (AlN) layer used as “active” material to generate an output voltage as function of the measur and (acceleration) without the adoption of supplementary/active conditioning circuits; 2) the use of a meander structure for higher performance, low frequency response and suitable to realize a low-stiffness device with, at the same time, high useful active area for the self-generating piezoelectric material (AlN). It is worth to mention that the proposed system can be used for novel measurement architectures which can be applied in several fields, including inertial measurement for equipments, sensing in environments, biomedical and structural health monitoring. The paper includes the design, fabrication modeling and experiments in order to demonstrate the validity of the proposed device.

Parkinson’s disease (PD) is a highly-disabling common neurodegenerative disease. The current method to diagnose PD is mainly based on clinical criteria and motor examination of the performance of the patients that are visually evaluated by the neurologist while they performed tasks from MDS-UPDRS. In order to support the clinician in objective assessment of the motor performance, sensorized wearable technology able to finely measure the motion are currently investigated. Since accuracy and precision of the measures are mandatory to provide the neurologist with a tool that can actually be applied in clinical practice, in this work, the quality of measures obtained by the SensHand system was evaluated, comparing them to an optoelectronic “gold standard” system addressing a preliminary technical validation. Three exercises (i.e., finger tapping, thumb-forefinger tapping, and pronosupination) were selected and frequency, number of repetitions and amplitude of the movements were measured for each of them by both the wearable and optical systems. The preliminary results were very satisfying, considering that discrepancies, measured as absolute error, in frequency evaluation, number of repetitions, and amplitude movement were, on average, equal to 0.03 taps/s(min0.02, max0.05), 0.07 tap (min 0.02, max 0.13), and 3.8 degrees (min 1.81, max7.47), respectively. Very high correlation values obtained from linear regression analysis (R2>0.9) also confirmed the accuracy of the measurements achieved with SensHand. Therefore, the obtained results from SensHand system are promising to use it to support the neurologist for accurate quantification of motion analysis to improve the objective PD evaluation.
帕金森病(PD)是一种高度致残的常见神经退行性疾病。目前诊断PD的方法主要基于临床标准和神经学家在执行MDS-UPDRS任务时对患者表现进行视觉评估的运动检查。为了支持临床医生对运动性能的客观评估，目前正在研究能够精细测量运动的传感可穿戴技术。由于测量的准确性和精确性是强制性的，为神经科医生提供了一个可以实际应用于临床实践的工具，在这项工作中，对SensHand系统获得的测量质量进行了评估，并将其与光电“金标准”系统进行了比较，解决了初步的技术验证。选择手指叩击、拇指-食指叩击和前旋三种动作，通过可穿戴和光学系统分别测量每种动作的频率、重复次数和幅度。考虑到以绝对误差衡量的频率评估、重复次数和振幅运动的差异平均分别等于0.03次拍/s(min0.02, max0.05)、0.07次拍(min0.02, max 0.13)和3.8度(min 1.81, max7.47)，初步结果非常令人满意。线性回归分析获得的非常高的相关值(R2>0.9)也证实了SensHand测量结果的准确性。因此，SensHand系统获得的结果有望用于支持神经科医生对运动分析进行准确量化，以提高PD的客观评估。

The work aims to provide the experimental assessment of a recently proposed near-field/far-field (NF/FF) transformation technique with spherical spiral scan, that, by properly exploiting the theoretical bases on the nonredundant representation of electromagnetic fields and on the spiral scans for nonvolumetric antennas, is able to account for mountings of the antennas under test (AUTs) in offset configuration. It will be shown that, to characterize an AUT with a quasi-planar geometry, suitably modelled by a flexible surface made by two circular bowls of equal apertures and possibly different lateral bends, the developed technique employs the same amount of NF data both for offset and onset AUT mountings, since this amount relies only on the area of the surface that contains the antenna. The experimental results will further confirm its practical efficacy.

This paper shows the feasibility of a novel humidity sensor based on a low frequency micromachined electromechanical resonator functionalized with nanoparticles of TiO2. Immunity to the non-idealities of the conditioning electronic components was obtained by means of a low frequency resonator. In addition, this method was also applied in order to minimize the degradation of the resonator quality due to the deposition of the sensing material. The experimental results obtained using an ad-hoc characterization system show that this solution is viable and that the sensor has satisfactory performance in a large humidity range. It is worth noting that the proposed system can be used for structural health monitoring and novel measurements architecture.

Structural Health Monitoring is becoming increasingly attractive for its potentialities in many application contexts, due to improvements brought in by non-destructive test technologies. Among them, Operational Modal Analysis is an efficient tool to assess the integrity of vibrating structures. This work exploits both novel MEMS accelerometers and piezoelectric devices to extract strictly synchronized modal parameters. The advantages of using a combined approach are proved by highly coherent results from an instrumented cantilever aluminum beam, which is able to provide exhaustive structural information.

The unmanned aircraft systems (UAS) are commonly used for aerial photography, express delivery for packets or video monitoring. The UAS technology can help responding to the growing demands of the frequency monitoring by national radiocommunication authorities (NRAs). This article presents a practical usage trial of an unmanned aircraft for monitoring the spectrum usage and finding the interference location. The monitoring of spectrum usage is one part of the NRAs’ process for guarantee user compliance with radio license conditions. Finding illegal or malfunctioning transmitters is a challenging task especially in urban environment, due to multi-path propagation conditions. This study focuses on practical assessment of the method for determining accurate location of radio frequency interference sources from the buildings using the UAS technology. The practicability of the UAS technology usage in spectrum monitoring activities was under the evaluation. This study showed promising results that UAS with the measurement equipment setup suits NRAs’ as a tool for mobile monitoring on the air.

The wide adoption of network based IT services to support operations and services have driven organizations to deploy local data center (DC) infrastructure and networks. Monitoring the proper functioning of such networks is of critical importance, specially in the event of failures. Timely detection and localization of the failed devices shorten the repair times and guarantee normal operation of infrastructure and services. In this work we propose a data-driven multiple failure localization approach based on device features obtained through passive monitoring. Namely, we set the localization problem as one of multi-label classification using high dimensional and high resolution data that is increasingly available with modern devices. Our results show that using simple base classifiers, the proposed methodology can yield high Hamming accuracy and acceptable compromise on false alarms, without relying on active monitoring.

Reliable Radar Cross Section (RCS) measurements require complex instrumentation systems, expensive and dedicated test ranges and operations, especially when dealing with full-scale targets. Thus performing RCS measurements using near field test ranges and non-ideally anechoic environments is a very attractive option. Applications related to these topics have recently been of increasing interest especially in the design-prototyping loop of low observable platforms and full-scale components. To this purpose, IDS has been developing and using reliable RCS measurement solutions and innovative processing techniques for more than fifteen years. This paper focuses on the major contributions to uncertainty in radar image based near field to far-field RCS measurement, by reviewing each of the principal sources of uncertainty, both random and systematic, and underlining possible error mitigation strategies.

Wireless Sensor Networks (WSNs) are widely explored because of their low cost, increasing capability of nodes, energy efficiency, accuracy and real time. A major issue is localization because it is based on the use of a number of sensor nodes deployed at unknown positions. Moreover, the need for more accurate and reliable localization system is increasing especially for certain applications, such as object tracking, surveillance, and disasters prediction. The reliability of the localization process should be investigated and external factors need to be considered in order to increase the accuracy of the localization. In this work, a localization system based on ultra-wide band technology is presented. The ranging system employs the two-way ranging method, which is based on the time of Arrival (ToA) technique. The DecaWave ranging system is, therefore, chosen for its high accuracy, which is about ±10 cm. To evaluate the proposed localization system, outdoor experiments were carried out, where the weather changes are considered. In this paper, the influences of weather changes on distance measurement are highlighted and a polynomial regression model for distance measurement prediction is provided with R-squared value of 78%. The regression model is designed to characterize the distance measurement variation in relevance to weather changes to enhance the localization system accuracy.
