“…Additional calculations were carried out by taking into account further MEMS sensors available in the literature, and in particular the wireless, three-axis MEMS devices designed by the University of Illinois, Urbana-Champaign, see [45] and Figure 3a. Such a solution was used for the SHM of the historical Basilica Santa Maria of Collemaggio in L'Aquila, Italy, after the 2009 seismic event [46][47][48]. The typical device-with a sampling range of DC-1500 Hz-consists of ISM400 sensor boards [49], and accelerometers (LIS344ALH type) produced by ST Microelectronics (Geneva, Switzerland).…”

“…The typical device-with a sampling range of DC-1500 Hz-consists of ISM400 sensor boards [49], and accelerometers (LIS344ALH type) produced by ST Microelectronics (Geneva, Switzerland). In [46][47][48], positive feedback was reported for the adopted wireless MEMS sensors, based on preliminary laboratory tests. At the same time, after one-year on-site data acquisition, the limited performance of LIS344ALH accelerometers was also highlighted, being responsible of major troubles for the identification of the dynamic parameters for the basilica object of study.…”

In recent years, thanks to the simple and yet efficient design, Micro Electro-Mechanical Systems (MEMS) accelerometers have proven to offer a suitable solution for Structural Health Monitoring (SHM) in civil engineering applications. Such devices are typically characterised by high portability and durability, as well as limited cost, hence resulting in ideal tools for applications in buildings and infrastructure. In this paper, original self-made MEMS sensor prototypes are presented and validated on the basis of preliminary laboratory tests (shaking table experiments and noise level measurements). Based on the well promising preliminary outcomes, their possible application for the dynamic identification of existing, full-scale structural assemblies is then discussed, giving evidence of their potential via comparative calculations towards past literature results, inclusive of both on-site, Experimental Modal Analysis (EMA) and Finite Element Analytical estimations (FEA). The full-scale experimental validation of MEMS accelerometers, in particular, is performed using, as a case study, the cable-stayed bridge in Pietratagliata (Italy). Dynamic results summarised in the paper demonstrate the high capability of MEMS accelerometers, with evidence of rather stable and reliable predictions, and suggest their feasibility and potential for SHM purposes.

Whilst researchers and professionals recognize that mobile health (m-health) systems offer unprecedented opportunities, most existing work has comprised individual project-based developments in specialised areas. Existing review articles generally utilise medical literature and categories: none investigates m-health from an information systems (IS) design point of view. Identifying application areas, design issues and IS research techniques will demonstrate models, issues, approaches and gaps to inform future research. A comprehensive analysis of the literature from this viewpoint is thus valuable, both for theoretical progression and for guiding real-world innovative system developments. Drawing from key IS and healthcare multidisciplinary journals we analyse recent (2010-2016) articles concerning m-health application developments and their associated design or development issues, with particular focus on the use of contemporary research methods. Our analysis suggests that m-health is an emerging field to which, although underused, contemporary approaches such as design science research are particularly appropriate. We identify eight application categories, eleven design issues (security, privacy, literacy, accessibility, acceptability, reliability, usability, confidentiality, integrity, knowledge sharing and flexibility) as well as the stakeholders and development techniques involved. This goes beyond previous frameworks, and theoretically integrates the central role of IS design within the sub-field.

“…In particular, research developments strive to reduce (i) the weight and cost of the sensing elements, (ii) the sensor network power consumption, and (iii) the cost for the deployment of centralized data acquisition systems, as well as (iv) the amount of cables [10][11][12][13] whereas, in the other end, aimed at (v) handling and sharing large amount of collected data.…”

A Sensor Network with Embedded Data Processing and Data-to-Cloud Capabilities for Vibration-Based Real-Time SHM

This work describes a network of low power/low-cost microelectromechanical-(MEMS-) based three-axial acceleration sensors with local data processing and data-to-cloud capabilities. In particular, the developed sensor nodes are capable to acquire acceleration time series and extract their frequency spectrum peaks, which are autonomously sent through an ad hoc developed gateway device to an online database using a dedicated transfer protocol. The developed network minimizes the power consumption to monitor remotely and in real time the acceleration spectra peaks at each sensor node. An experimental setup in which a network of 5 sensor nodes is used to monitor a simply supported steel beam in free vibration conditions is considered to test the performance of the implemented circuitry. The total weight and energy consumption of the entire network are, respectively, less than 50 g and 300 mW in continuous monitoring conditions. Results show a very good agreement between the measured natural vibration frequencies of the beam and the theoretical values estimated according to the classical closed formula. As such, the proposed monitoring network can be considered ideal for the SHM of civil structures like long-span bridges.
