New XSENSOR study validates insole sensor long-term stability

A new validation study has been released which demonstrates the long-term calibration stability of XSENSOR’s Intelligent Insole pressure sensors.

A long-term evaluation was conducted to confirm the accuracy and repeatability of the Intelligent Insole pressure sensors used to measure plantar pressure during gait and standing. The sensors were each subjected to 200,000 cycles of controlled loading and of flexing, representing approximately three years of normal clinical* or equivalent use. Measurements were taken at regular verification intervals and compared against calibrated reference loads across a range of pressure levels.

Results demonstrated that the sensors maintained measurement accuracy within 3.2% of full-scale error and repeatability of 3.4%, with no significant drift observed over the test duration. These findings confirm the long-term calibration stability of the pressure measurement system.

Based on the results, routine recalibration is not required within three years of normal clinical use, ensuring confidence in consistent, high-quality data for clinical and equivalent plantar pressure measurement applications.

* Normal Clinical Use: Under estimated normal clinical use conditions, the sensors are employed during walking tests conducted five days per week for three years, with five sessions per day and 60 test steps per session, resulting in approximately 200,000 sensor cycles over the duration of use.
