Activity-related energy expenditure (AEE) might be an important factor in the etiology of chronic diseases. However, measurement of free-living AEE is usually not feasible in large-scale ...

Meggitt Sensing Systems has made available its Endevco model 2280, a hermetically sealed, triaxial, piezoelectric charge output accelerometer with high-temperature operation to 482 degrees C (900 ...

How do piezoelectric accelerometers — vibration sensors — work? The force caused by vibration or a change in motion (acceleration) causes the sensor's mass to “squeeze” contained piezoelectric ...

The three-axis LIS3DH digital-output accelerometer consumes as little as 2 μA of power and provides output across full-scale ranges of ±2, ±4, ±8, and ±16g. It contains a sensor and three ADC channels ...

To sense shock, vibration, and/or linear motion, accelerometers are beginning to appear in a broad range of new applications. Common types of accelerometers for these applications�various ...

One of the most difficult aspects of selecting an accelerometer for a particular application is interpreting the accelerometer’s specifications. Often you understand your test requirements well but ...

Dmitry Vasilenko, of Arrow Electronics, provides some design hints to accelerate the mechanical model of an accelerometer. Micro-mechanical systems (MEMS) have become common. They are used for ...

This one’s pretty simple, but anyone who’s ever spent time tweaking an engine will appreciate it. [Kevin]’s been using a wiimote to measure the acceleration of his car. He put together a script to ...

Last fall, I grabbed a robot arm from Robot Geeks when they were on sale at Thanksgiving. The arm uses servos to rotate the base and move the joints and gripper. These work well enough but I found one ...
