Flexible 2D Goniometer

Flexible Goniometer

1 or 2D Goniometer with flexible axis sensor
for Noraxon cable and telemetry systems

  • Measures angular displacement
  • Measures one or two dimensions
  • Easy to use flexible axis
  • Available in 5 sizes

The flexible goniometer developed by Biometrics LTD UK has been an established standard worldwide. Due to its flexible axis construction and five available sizes, it can be used on most body joints. It is available in a one or two axis configuration measuring e.g. flexion/extension and lateral flexion (spine) in one application.

Versatile use due to flexible axis

A flexible spring connection between the two goniometer blocks compensates for any joint migration and surface prolongation, which is especially helpful in shoulder joint and spine motion. It also allows for placement of the sensor on uneven surfaces. Due to the amplifier built into the cable, it has direct plug-in functionality to Noraxon devices.

The sensor has a predefined measurement setup configuration in all the Noraxon software packages and is operational in a few seconds:

Application Examples

The Biometrics sensor line addresses all major joints of the human
body. The flexible design allows for use in numerous application
areas, such as medical research, sports analysis, rehabilitation,
ergonomics, and robotics. The sensor may be attached with Velcro
straps or adhesive tape.
