Dark matter is one of the biggest open questions in physics today. It known that it interacts gravitationally with luminous matter, so accelerometer-based searches are inherently interesting. In this article we present recent (and future) for dark candidates such as feebly interacting trapped inside Earth, scalar-matter domain walls and axion quark nuggets, accelerometer networks give an outloo...

A cost-effective method was developed for the estimation of the bow velocity in violin playing, using an accelerometer on the bow in combination with point tracking using a standard video camera. The video data are used to detect the moments of bow direction changes. This information is used for piece-wise integration of the accelerometer signal, resulting in a drift-free reconstructed velocity...

An integrated system comprising GPS, accelerometer, and optical fibre sensors has been proposed to monitor structural deformation in order to assess the integrity of the structure. The GPS and accelerometer sensors have been installed on a 108m tall steel tower, and data have been collected during Typhoon No. 21 on 1 October 2002, at 10Hz and 20Hz rates respectively. The wind induced deformatio...

INTRODUCTION Accelerometers are becoming an increasingly important tool in the study of human movement. Their ease and affordability, combined with the potential to collect large amounts of continuous data outside the laboratory setting makes them excellent tools for gait analysis. Research has demonstrated the effectiveness of a single tri-axial accelerometer in measuring mean spatiotemporal p...

In order to meet the requirements of cable fault detection, a new structure of piezoelectric accelerometer was designed and analyzed in detail. The structure was composed of a seismic mass, two sensitive beams, and two added beams. Then, simulations including the maximum stress, natural frequency, and output voltage were carried out. Moreover, comparisons with traditional structures of piezoele...

A high-precision angular accelerometer based on molecular-electronic transfer (MET) technology with a high dynamic range and a low level of self-noise has been developed. Its difference from the analogues is in the use of liquid (electrolyte) as the inertial mass and the use of negative feedback based on the magnetohydrodynamic effect. This article reports on the development of the angular mole...

This paper presents a novel digital closed loop microelectromechanical system (MEMS) accelerometer with the architecture and experimental evaluation. The complicated timing diagram or complex power supply in published articles are circumvented by using a charge pump system of adjustable output voltage fabricated in a 2P4M 0.35 µm complementary metal-oxide semiconductor (CMOS) process, therefore...

We present the design and fabrication of a single axis low noise accelerometer in an unmodified commercial MicroElectroMechanical Systems (MEMS) process. The new microfabrication process, MEMS Integrated Design for Inertial Sensors (MIDIS), introduced by Teledyne DALSA Inc. allows wafer level vacuum encapsulation at 10 milliTorr which provides a high Quality factor and reduces noise interferenc...

In this work a low cost Arduino based Bridge health monitoring system is proposed. This uses Web Server with IP connectivity for accessing accelerometer readings. Statistical signal processing of readings obtained from sensors involve intensive calculations. As a result processors that support large data size and high duty cycles are required for data assessment. Internet of things (IoT) helps ...

[Purpose] This study investigated the sensitivity of an accelerometer in a comparison with the Action Research Arm Test (ARAT). [Subjects] Fifteen stroke patients participated in this study. [Methods] Subjects wore accelerometers on both wrists and performed the ARAT items. We then compared the data measured by the accelerometer with that of the ARAT. [Results] ARAT scores were higher on the no...
