Application of MEMS‐based accelerometer wireless sensor systems for monitoring of blast‐induced ground vibration and structural health: a review

Abstract

Ubiquitous wireless sensor network (WSN) enables low-cost monitoring applications such as blast-induced ground vibration (BIGV) and structural health monitoring (SHM). In particular, monitoring and analysing the ambiguous BIGV waves are essential requisite to control and protect surrounding grievous damage structures. Similarly, improving health and longevity of structures using WSN is a new facet that owes to diminish the low-cost installation. Recent advances in WSNs are forging new prospects for sensors. A variety of intelligent sensors are integrated into the wireless system to monitor environmental, and health of civil infrastructures. Considering the current trends in the area of development of wireless monitoring prototypes, Micro-Electro-Mechanical-Systems (MEMS) accelerometer sensors are widely prevalent owing to the small size and inexpensive. In general, BIGV waves are less intensity and low-frequency signals. Hence, it is essential to select an appropriate accelerometer to detect micro-vibration waves. The study exemplifies a summarised review of recently made MEMS-based accelerometer wireless systems for intelligent and reliable monitoring of BIGV and SHM since the last decade. This research effort focuses on the numerous adopted accelerometers and their characteristics such as sensitivity, noise density, measurement range, bandwidth, resolution, network topologies, and performance of designed systems to analyse the microvibration levels comprehensively.

Performance evaluation of LoRa LPWAN technology for IoT-based blast-induced ground vibration system

“…Over the past decades, multiple researchers, scientists, and academicians have been adopted by conventional monitoring systems to measure the BIGV in open cast mines. The most commonly available seismographs are Instantel Minimate Plus, Minimate Pro, UVS 1500, and MR 202-CE represents in Fig 1. However, the existing cable-based seismographs have some flaws such as: susceptible to failure due to breakage in the wire; wire impedance owing to the length of wire not possible to extend; cannot convey the retrieved data in real-time; expensive system; limited storage memory; need an expert to operate; tedious and time-consuming process [2].…”

Structural Health Monitoring system with Narrowband IoT and MEMS sensors

“…These measurements have low bandwidth and can be performed with very low power sensor and electronics, which can survive in the building for all its lifetime. Our work focuses on much higher bandwidth vibration-based analysis, which is as essential for SHM as static analysis since it provides complementary information [13], [19], [22]. Ideally, dynamic analysis should be performed in a continuous, long term fashion, in parallel with static analysis, but it generally is not, because of power and cost concerns.…”

“…In literature, [24], [25] provides several examples and evaluations on wireless communication applied to SHM, but none of them use NB-IoT. Also, in [22] are presented some examples of SHM systems based on MEMS sensors, but in all proposed solutions, the usage of NB-IoT is not considered.…”

A Review of the Capacitive MEMS for Seismology

“…It is about making a choice between technical-scientific needs and the financial affordability and, again, MEMS technology helps to overcome such a compromise. Not only the cost of the sensors can be drastically cut, but also the cost to wire a building because the miniaturized MEMS-based monitoring stations can be easily connected wireless and manage real-time data [89,90,91].…”
