'We created a piezoresistive NEMS accelerometer
that is dramatically smaller than any MEMS accelerometers
available today, but retains the sensitivity these systems require.'
After 3 1/2 years, each daily hour of light activity (on the accelerometer
) was linked to a 20 percent lower risk of a heart attack and a 10 percent lower risk of any cardiovascular event (like stroke, heart failure, or angioplasty).
A team of researchers from Imperial College London and photonics firm M Squared have demonstrated the UK's first commercially viable, transportable and standalone quantum accelerometer
The vendor offers various charge amplifiers to support the launch of these new accelerometers

Lord a Colvin  studied the causes and consequences of falls in seniors, tried to prevent falls and proposed the use of a fall detection accelerometer
. The first prototype fall detector was developed in 1998.
have been worn on a variety of anatomical positions, but most often worn on the hip or wrist, with the latter being the most common due to its high acceptability to study participants [7-9].
At all distances in which accelerometers
are placed, vibration can be detected.
With more electronics being packed into accelerometers
, they are becoming more sensitive to environmental factors like temperature.
* A propriety coupling of low-noise MEMS accelerometers
and advanced algorithms
Besides typical measurements of acceleration related to vibration or motion, another basic application of accelerometers
is tilt measurements .
This article expands on that work with differences on the following: (1) correction method for both single accelerometer
and multiple accelerometers
cases are discussed; (2) experiments validation, analysis, and discussions are supplemented except for numerical case study.
In this system, 3-axis digital accelerometers
were used for the measurement of head position.
There are many ways to carry out measurements of the inertial response of three-axis accelerometers
Their most common applications include: accelerometers
, sensors of pressure, chemical sensors, flow sensors, as well as optical scanners and pumps of flow.
announces three-axis, MEMS accelerometers
that perform high resolution vibration measurement with very low noise to enable the early detection of structural defects via wireless sensor networks.
