Education in I&M: New Insights in Remote Teaching and Learning of Instrumentation and Measurement: The iHomeX Remote Lab Project
No full textNowadays, thanks to the recent developments both in pedagogy and information and communication technologies, new ideas have made their way into the design and development of educational methodologies. From one side, pedagogy focused the attention on all of the variables which interact in the teaching and learning process, when teachers and learners work toward their goals and incorporate new knowledge, behaviors, and skills that add to their range of experiences. On the other side, web-based learning and networking activities allow the development of new distance learning methodologies using online platforms, multimedia, and teaching techniques to immerse students in a community of learners

No full textTC-25: The Latest Activities of Technical Committee on Biological and Medical Measurements
No full textThe Technical Committee on Biological and Medical Measurements (TC-25) aims at establishing, developing, promoting and supporting the cooperation among researchers in the different fields of biological and medical measurements. Sensors for the measurement of clinical and/or biological parameters, instrument and procedure characterization, instrument interoperability and interconnection, and data processing are some of the topics of interest to the TC-25. To those aims, the technical committee designs and realizes joint activities, like study groups aimed at standardization, such as the Subcommittee on Blood Pressure Measurement (SCOBPM), conferences or special sessions, such as the IEEE International Symposium on Medical Measurements and Applications, and several special sessions during the annual IEEE Instrumentation and Measurement Technical Conferences. The TC-25 is also continuously engaged to maintain liaisons with other committees, groups, societies and organizations working on topics related to the TC's scope
Special issue on medical measurements [Guest Editorial]
No full textThis special issue of the IEEE I&M Magazine contains a concise but significant selection of contributions to the research in measurement for medicine, as provided by researchers from universities and industry, who are interested in developing novel solutions to the instrumentation and measurement (I&M) problems that are encountered in modern health care. The papers are mainly extended versions of contributions presented at the annual IEEE International Symposium on Medical Measurements and Applications (MeMeA), sponsored by the IEEE Instrumentation and Measurement Society. MeMeA is an annual conference devoted to all aspects of interaction between measurement and medical fields with the aim of highlighting how measurements represent a real challenge for collecting correct and trustworthy data for patient healthcare. MeMeA is a place where measurement specialists, electronic and bioelectronic equipment designers and users of measurement methods and instrumentation can share their points of view, experiences, results and form new joint multidisciplinary and international research groups. MeMeA contributions include sensor design and calibration, instrument and virtual instrument design and calibration, measurement methods, analysis of measurement results, measurement image and signal processing for medicine

Started in 2006, MeMeA has become a successful international annual meeting for all scientists interested in measurements for medicine, coming from academia, industry and research institutions from all over the world, offering them the opportunity to work together toward the development of feasible and effective solutions for real-world problems related to patient healthcare
Medical measurements: A need and a challenge
No full textMedical measurements and devices continue to deal with the measurands' variability over time and among patients due to a multitude of intrinsic and extrinsic factors; then, there is an increasing need of sensors and embedded systems for noninvasive measurements. Furthermore, the reliability, accuracy, and efficiency of the implemented methods and systems are the main concerns of researchers in medical measurements and applications in a context of increasing cost-conscious customers, governments, and regulatory agencies

No full textSurface treatments to enhance the sensitivity of plastic optical fiber based accelerometers
No full textThe paper discusses the possibility to improve the sensitivity of a plastic optical fiber based accelerometer using physical treatments on the polymer surface to modify the light propagation characteristics. The considered accelerometer, having the target of being low-cost and compact, exploits the variation of propagation loss along the fiber induced by the deformations of a miniaturized cantilever on which the fiber is fixed. This simple setup, however, does not exhibit a sufficient sensitivity unless the fiber surface is properly treated in order to enhance the loss dependence with the cantilever bending. Two approaches are compared, namely plasma micro- and nano-texturing and laser localized ablations. Several prototypes of accelerometers have been fabricated using various types of plastic fibers and characterized using a vibration test facility. Preliminary results show that both techniques are effective, although most recommended for different types of applications. In particular, the laser localized ablation has proved to be the most suitable to realize accelerometers for industrial applications, like the monitoring of vibrations due to moving parts of machine
A Remotely Controlled Calibrator for Chemical Pollutant Measuring-Units
Full text linkThe increasing diffusion of pollutant measuring units, which are installed over wide areas, along with the short calibration interval of several sensors for pollutant quantities, requires new calibration infrastructures to be developed. This paper describes an attempt to develop an innovative calibration system which is based on traveling standards and which does not require units to be removed from the measuring site during the calibration process. The calibration system is based on a traveling standard, which is composed of one or more cylinders that contain gas mixtures, a cell with standard sensors, and a control unit with networking capabilities, which allows the traveling standard to be remotely exercised. A prototype of the proposed system is described and the preliminary results reporte
Inert thermocouple with nanometric thickness for lyophilization monitoring
No full textThis paper describes the development and characterization of thermocouples with nanometric thickness made inert by means of a glass-like coating. These thermocouples are designed to follow the freeze-drying process of pharmaceutical products without perturbing freezing and drying steps but can be used in several other applications where the perturbation introduced by wire thermocouples can prevent a correct measurement to be performed. The developed thermocouples are T-type with a thickness in the range of 50-200 nm and are embedded into the vial wall owing to a SiO2-like coating with a glass-like structure and a thickness of 200 nm. This way, they actually measure the product temperature without altering thermal distribution and shape of the drying front and withoutmodifying the cake structure during the freezing step, so that the results can be extended to the other not instrumented vials. The SiO2-like coating ensures that no ion exchange takes place between thermocouple metals and lyophilized product, thus avoiding the risk of contamination and denaturation. The extremely low thickness requires a preliminary characterization of the thermocouples in order to determine their Seebeck coefficient, but the sealing provided by the coating, which prevents oxidization and degradation of the metallic strips, ensures that the obtained coefficients can be used for a long tim
