Publication integrity record
Infinite-rotation infinite-stiffness variable stiffness actuator (IRISVSA) with application for compliant supernumerary robotic limb
This page is the evidence record. It changes as evidence arrives: a trusted timestamp, an independent retrieval, a custody deposit. The disclosure itself (/p/OT-2026-000000194) never changes.
