Enhanced two-dimensional superelasticity in a laser micromachined auxetic NiTiNOL geometry

Year: 2025

Type: article

Abstract: The superelastic effect in nitinol allows it to accommodate and recover large amounts of deformation. Despite possessing this incredible ability, their use in applications remains limited due to the difficulty in machining into novel geometries like auxetics. Laser-micromachining is an attractive solution to this problem, with the ability to micromachine geometries not conventionally possible. Such geometries, like auxetics, could be used to enhance the simultaneous two-dimensional accommodation and recovery of superelastic strain. We showcase an example of this enhancement in a laser-micromachined auxetic geometry that has minimal material removal.
