A 4D printed active compliant hinge for potential space applications using shape memory alloys and polymers
Jamie Paik, Zhenishbek Zhakypov, Jian-Lin Huang, Ralph Spolenak
This paper presents the proof-of-concept for a 4D printed active compliant hinge with a selectively variable stiffness for the deployment and reorientation of satellite appendages. We use 4D printing to create an active compliant hinge capable of bending t ...
IOP PUBLISHING LTD2021Hinges for origami-inspired structures by multimaterial additive manufacturing
Jamie Paik, Jian-Lin Huang, Ralph Spolenak
Recent studies demonstrate novel metamaterials featuring unique properties by combining origami-inspired designs with additive manufacturing. In particular, the use of flexural hinges endow distinct advantages toward miniaturization and fabrication; howeve ...
2020Hinges for Origami-Inspired Structures by Multi-Material Additive Manufacturing
Jamie Paik, Jian-Lin Huang, Ralph Spolenak
Additive manufacturing of structures capable of changing their properties or shape in a programmed controlled manner is a booming research field. A large number of studies show that the unique capabilities of 4D printing (freedom of geometrical design spac ...
2019Selective ion-induced grain growth: Thermal spike modeling and its experimental validation
Ion-bombardment-induced selective grain growth is a process that allows for full control of the orientation of vapor-deposited thin films, which can be converted from fiber-textured polycrystalline to single-crystal films. The main mechanisms behind this p ...
