Tactile Skin & Sensing
From bump sensors to whole-body artificial skin with thousands of sensing points.
3 years ago (2023)
Basic contact and force sensors on gripper fingertips. Bump sensors for collision detection. No full-body tactile sensing. iCub had some experimental skin patches. Safety relied on torque sensing and force-limited joints.
Now (2026)
KAI's tactile skin has 18,000 sensors across its body, detecting forces as light as 0.1N. Clone Robotics uses myomorphic artificial muscle with integrated sensing. Synthetic skin covers full-size humanoids. Temperature sensing being integrated. Pain reflex circuits in development.
Next 3 years
Self-healing skin layers that repair minor damage. Texture discrimination (silk vs. sandpaper). Moisture detection for safe object handling. Full-body haptic feedback for teleoperation. Sensing density approaching human fingertip resolution (500+ sensors/cm2).
