Measuring vibration,
linear and angular motion Applications that require precise information on the linear or angular movement of an object rely on the accuracy of motion sensors within, says Richard Mount, director of sales at ASIC design and supply company Swindon Silicon Systems

ccelerometers and gyroscopes can be used to provide this movement data, and utilising developments in MEMS technologies means this is all possible within a much smaller space envelope. But as we push for increased functionality in smaller spaces, what can custom ICs do to benefit?
In consumer devices, motion sensors offer
an additional layer of functionality to provide a more user-friendly and immersive experience. They’re what allow game controllers to recognise tilting and rotational movements, as well as to register when you turn your phone sideways to watch a video or view a landscape image.
34 September 2023 Irish Manufacturing Accelerometers can recognise these
movements by measuring proper acceleration, with both single and multi-axis accelerometers available to determine magnitude, direction and orientation. In the manufacturing plant, accelerometers may be deployed to perform a range of tasks, including tilt and inclination measurements and impact recognition and logging. It’s also possible to facilitate machinery health and condition-based monitoring (CBM) in this way, by converting acceleration into vibrational information.
Misalignments or faults with shafts or bearings are likely to cause changes in vibration that can be picked up by the system. Therefore, combining strategically placed accelerometers
around the plant with IoT technologies helps to enable predictive maintenance, by allowing the system to flag any potential issues before they become serious. For information on angular velocity, it’s
preferable to employ a gyroscope. Able to measure rotation around one, two or three axes, gyroscopes are commonly used in applications that require stability. This includes military applications to provide stabilised launch and landing platforms for unmanned aerial vehicles (UAVs), as well as aviation applications to monitor aircraft altitude. It’s also possible to combine accelerometers with gyroscopes for more accurate data on the object’s movement.
