Variable Stiffness Fiber with Self-Healing Capability

Variable Stiffness Fiber with Self-Healing Capability

A variable stiffness fiber made of silicone and low melting point alloys quickly becomes >700 times softer and >400 times more deformable when heated above 62 °C. It shows remarkable self‐healing properties and can be clamped, knitted, and bonded, as shown in a foldable multi‐purpose drone, a...

Zusammenfassung:A variable stiffness fiber made of silicone and low melting point alloys quickly becomes >700 times softer and >400 times more deformable when heated above 62 °C. It shows remarkable self‐healing properties and can be clamped, knitted, and bonded, as shown in a foldable multi‐purpose drone, a wearable cast for bone injuries, and a soft multi‐directional actuator.
