VabricBeads :Variable Stiffness Structured Fabric using Artificial Muscle in Woven Beads, ACM CHI ‘24
Woven beads, a structured fabric category, comprises interconnected rows of beads joined by fiber strands. While the stiffness of woven beads can be adjusted by relying on fiber tension during fabrication, the resulting shape and stiffness properties remain fixed. This study explores the potential of tunable shape and stiffness in woven beads, offering adaptability in comfort, functionality, and form factor. By leveraging Pneumatic Artificial Muscles (PAMs), we employ a state-of-the-art technique for dynamically modulating fabric stiffness through mechanical constraints in bead form. This approach enables a modular and scalable fabrication process, fostering programmability in mechanical properties. Our investigation encompasses diverse bead iterations and stitching patterns to broaden their applicability in fabric behavior including degree of freedom, stretchability, permeability, and textures. We evaluate the mechanical properties to differentiate design capabilities, and present techniques for locally adjusting stiffness. We showcase the versatility through applications, including variable stiffness wearables and shape-changing everyday objects.

ASTRE : Prototyping Technique for Modular Soft Robots With Variable Stiffness, IEEE Access ‘22
Soft robots are advantageous for human interaction owing to their adaptability and safe interactivity. However, research on soft robots is challenging because of the complex fabrication process of elastomeric materials with multiple channels. In this study, we introduce a prototyping technique for the fabrication-friendly soft robots using pneumatic artificial muscle(PAMs) and modular 3D printed reinforcement. We presented three primitive deformation structures :bending, twisting, and contraction. Moreover, we propose a novel variable stiffness technique that alters PAMs contraction and radial expansion behavior into locking, malleable, and rotational brake features. We explore both the parallel and series arrangement of the reinforcement module and propose new types of mixing configurations and scaling techniques. We quantitatively verified the force scaling technique on different types of features. We demonstrate the feasibility of this prototyping technique through six application examples and conclude with a discussion of the limitations and possible future improvements.

ClaytricSurface: An Interactive Deformable Display with Dynamic Stiffness Control, IEEE CG&A ‘14
ClaytricSurface is a shape-changeable display with dynamic stiffness control. The prototype uses vacuum pressure control on an enclosed volume of particles. Users can mold 3D shapes and apply textures to them while experiencing tactile feedback through dynamically changing stiffness. The system’s developers have added both touch input using a depth camera and peripheral devices to expand the system’s practical application. They also developed applications in the form of design tools that have great entertainment potential.
