Long-term pressure-insole reliability

Evaluate the long-term durability, measurement drift, and recalibration requirements of the pressure insole used by TactileStep.

Background

TactileStep relies on sole-pressure insoles to provide force, contact-area, and center-of-pressure observations during deployment. The experiments do not establish whether these sensors maintain reliable measurements over prolonged operation or how frequently they require recalibration, leaving their long-term suitability for humanoid deployment unresolved.

References

Long-term sensor durability, drift, and recalibration of the pressure insole are also not evaluated.
