Elastic movement sensors and calibration

A sensing system comprising:

• an elastic sensor configured to sense a movement,
• an inertial measurement system for sensing a movement,
• a controller programmed for obtaining movement sensing data from the elastic sensor and from the inertial measurement system and for calibrating the elastic sensor using the combined movement sensing data from the elastic sensor and the inertial measurement system,
• wherein the controller is programmed to trigger a simultaneous measurement to obtain measurement data by the elastic sensor and the inertial measurement system and to derive calibration data for the elastic sensor based on a combination of the measurement data obtained during the simultaneous measurement, and
• wherein the controller is programmed to, in a later phase, use the elastic sensor for re-calibrating the inertial measurement system or calibrating other inertial measurement systems.
