Design and 4D Printing of Cross-Folded Origami Structures: A Preliminary Investigation
In 4D printing research, different types of complex structure folding and unfolding have been investigated. However, research on cross-folding of origami structures (defined as a folding structure with at least two overlapping folds) has not been reported. This research focuses on the investigation of cross-folding structures using multi-material components along different axes and different ho...
متن کامل4D Printing for Freeform Surfaces: Design Optimization of Origami and Kirigami Structures
A self-folding structure fabricated by additive manufacturing can be automatically folded into a demanding 3D shape by actuation mechanisms such as heating. However, 3D surfaces can only be fabricated by self-folding structures when they are flattenable. Most generally designed parts are not flattenable. To address the problem, we develop a shape optimization method to modify a non-flattenable ...
متن کاملAn End-to-End Approach to Self-Folding Origami Structures by Uniform Heat
This paper presents an end-to-end approach to automate the design and fabrication process for self-folding origami structures. Self-folding origami structures by uniform heat are robotic sheets composed of rigid tiles and joint actuators. When they are exposed to heat, each joint folds into a preprogrammed angle. Those folding motions transform themselves into a structure, which can be used as ...
متن کاملReconfigurable Antenna Structures Using Mems Technology
The tunable characteristics of RF MEMS (Microelectromechanical Systems) components enable their integration with antennas providing numerous advantages such as reconfigurability in polarization, frequency, and radiation pattern [1]. Furthermore, the monolithic fabrication of these components with antennas can reduce parasitic effects, losses and costs. This paper presents two tunable frequency ...
متن کاملOrigami tubes assembled into stiff, yet reconfigurable structures and metamaterials.
Thin sheets have long been known to experience an increase in stiffness when they are bent, buckled, or assembled into smaller interlocking structures. We introduce a unique orientation for coupling rigidly foldable origami tubes in a "zipper" fashion that substantially increases the system stiffness and permits only one flexible deformation mode through which the structure can deploy. The flex...
