Abstract

Motion sensors like MEMS accelerometers and gyroscopes (gyros) are rather small, cheap and reliable sensors that have found their place in a variety of applications. Some of the applications are in the field of human motion measurements. This is a growing market field and an increasing number of MEMS sensors find their way into products for human measurements, such as fall detection, running sensor, movement capacity analysis and stress measurement. In many of these applications the sensors are supposed to be worn by a human for a longer time to track their movements in one way or another. For MEMS gyros in particular, it is interesting to study the sensors reactions to typical human movements over time. Comparing humans and machines, human movements are often smoother and more oscillating than the more linear movement pattern of a machine. Datasheets for gyros usually only specify hard performance like resistance to impact and shock. It is also quite common that the datasheets are incorrect, especially for brand new sensors being released in new versions.
