Product Overview
The inclination sensor measures the angle relative to gravity and can simultaneously detect two motion directions, e.g. coupling patterns - combined saggital and frontal movements during cervical flexion.
Light Weight and User Friendly
It is the smallest inclination sensor available on the market and has full “plug-in” functionality to all Noraxon’s latest systems. The inclinometer is a universal motion detector and may be used for all body segments and joints. Due to its two dimensional capabilities, it reduces evaluation times as it allows the user to measure joints in two directions without sensor repositioning. The inclinometer is easily applied with double sided adhesive tape (see picture right side) or Velcro straps (see applications) .
If it is mounted on a lever arm of any training machine, it can be used as motion trigger signal. This is especially helpful for training in predefined motion ranges or if an accurate position signal is required for e.g. EMG and force measurements.
Free motion can be controlled by using the inclination sensor signals as a biofeedback signal.
The sensor measurement range is +/- 90 if both x and y axis are used simultaneously and +/- 180 if only one axis is used.
The sensor has a predefined measurement setup in all the Noraxon software packages and is operational in a few seconds:

Application Examples
The sensor can be used to detect the joint motion of most major joint regions: Hand, arm, shoulder, head, trunk, thigh, shin, and foot.
