Lightweight and High‐Performance Ankle Braces Enabled by 3D Printed Metamaterial Liquid Crystal Polymer

Advanced Materials Technologies, EarlyView.
A flexible, lightweight ankle brace made from 3D‐printed liquid crystal polymer metamaterials offers targeted support without restricting movement. Programmable stiffness provides protection during risky motions. Biomechanical tests suggest performance comparable to commercial braces with reduced bulk, highlighting potential for broader orthotic ...
