Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
A near-field/far-field transformation for circular aperture antennas, formulated as a linear inverse problem, is here proposed. The approach takes into account for the a-priori information about the radiating and geometrical characteristics of the antennas under test, by representing the aperture field with Circular Prolate Spheroidal Wave functions.
In this paper we present characterization of a soft, flexible and stretchable piezoelectric transducer towards its use as mechanical energy scavenger. In particular here we address the mechanical to electrical conversion process, an intense characterization procedure has been performed in order to evaluate the performance of a conformable piezoelectric foil. The proposed transducer and the measurement...
A novel technique based on the Field Mapping Algorithm (FMA) is proposed to gauge reflector surface smoothness from near-field reflector measurements. The proposed method provides exact information of the antenna surface with much less computation time compared with other available techniques. A few examples are given to illustrate the advantages of the new surface-analysis technique.
The aim of this contribution is to discuss an environmental filtering technique in array diagnosis. The basic idea is to distinguish the array contribution from the interference field using sparsity as discriminant by means of differential measurement technique. Basically, the field associated to the fault elements is separated by the field radiated by interference source using a mixed minimum ℓ1...
A new technique is presented for highly accurate far-field patterns obtained from spherical measurements in the near field of electrically large antennas. The proposed technique is based on the Field Mapping Algorithm, which provides exact fields on any desired surface from near-field data measured over a planar, cylindrical, or spherical surface. This method makes it possible to calculate complete...
In this paper, a detailed study on the applicability of various current sensor technologies and the corresponding measurement accuracy for power consumption characterization of Wireless Sensor Networks (WSN) nodes is presented and discussed. This study is useful to plan strategies to increase the life of the network and to plan the replacement of the sensor node before a failure occurs. Power consumption...
In this paper, a technique for accurate estimation of the moment of magnetic dipole is proposed. The achievable accuracy is investigated, as a function of measurement noise affecting estimation of magnetic field cartesian components. The proposed technique is validated both via simulations and experimentally.
This work aims to present the results of the first phase of crowdfunding campaign devised to involve general public in the development of a portable device for air quality monitoring and the associated infrastructure. A portable device based on an array of electrochemical sensors has been developed and calibrated in lab in order to build detailed maps of personal exposure to air pollutants with the...
This paper presents a measurement system for UHF-RFID tag detection employing leaky coaxial cable as distributed reader antenna. The proposed system is characterized through an experimental analysis in terms of S-parameters. Then the leaky feeder is employed in a measurement setup with commercial UHF-RFID reader. Measurement results show the leaky feeder capability to detect tags independently on...
Brain-Computer Interface (BCI) is an innovative communication technique mainly used in biomedical applications for assisting devices. In this context, main aim is help people with severe disabilities restore the movement ability, or replace lost motor function controlling external devices, or communicate with other people leading them to become more self-sufficient. The connection between BCI and...
The paper deals with the definition, implementation and performance assessment of an Internet of things (IoT) platform for measuring and monitoring power consumption in smart home or smart industry applications. Thanks to the adoption of suitable cost-effective hardware components and a proper software architecture implemented on Raspberry PI, the IoT platform can assure real-time power monitoring...
Scientific proposals of indoor positioning and range measurement are reviewed, with a discussion of their advantages and disadvantages. The considered technologies are: Radio Frequency, Ultrasonic, Camera-based solution, and Infrared. The typical constraints in indoor environments are high accuracy, low latency, low dimensions, and low energy dissipation.
The current revolution of the manufacturing sector, usually referred to as Industry 4.0, is deeply modifying the traditional production paradigms. The availability of cost-effective sensing and/or computing elements as well as ad-hoc communications protocols are, in fact, making it possible to provide the whole supply chain with a global awareness about the production process. Selecting the most adequate...
A tele-monitoring system, based on a soft transducer network, developed by students of the Course "Measurements on Communications Network" (MRC), at the Department of Electrical Engineering and Information Technology, University of Naples Federico II, is presented. This project is the result of an innovative education approach for (i) overcoming specialization of single Courses on different...
This paper proposes the realization and preliminary characterization of a smart sensor platform for the online monitoring of the residual life of activated carbon air based filters. The platform performs the measurement to give reliable information about the filter maintenance or early warning for the presence of dangerous gases both in industrial and military scenarios. A preliminary feasibility...
An automatic system for health data management and service report generation from Android OS smartphones was designed and implemented. QR Code is used as an identifier and a tracking tool for patients involved in rehabilitation treatments. The system was implemented both in a rehabilitation gymnasium and in a hospital ward. The experimental results highlight clearly an efficiency improvement in health...
