Proactive Robotic Grasp Stability via Tactile Safety Margin Feedback

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 5, May 2026.
We introduce the tactile safety margin (TSM), defined as the ratio between applied friction force (Ffric) and maximum friction (Fmax) derived from grip force. A bilayer E‐skin with decoupled temperature, strain, and pressure sensing enables real‐time grasp stability monitoring through measured TSM values, allowing robots to proactively adjust grip ...
