DropPop: Designing Drop-to-Deploy Mechanisms with Bistable Scissors Structures

Deployable structures often rely on complex deployment mechanisms such as external pneumatic pumps, electric motors, or manual assembly. These conventional methods, which are intended for applications in shape morphing architectures, robotics, and product design, can be bulky and unwieldy for everyday interaction and…

Wearable Material Properties: Passive Wearable Microstructures as Adaptable Interfaces for the Physical Environment

Users interact with static objects daily, but their preferences and needs may vary. Making the objects dynamic or adaptable requires updating all objects. Instead, we propose a novel wearable interface that empowers users to adjust perceived material properties. To explore such wearable interfaces, we design unit cel…

ElectriPop: Low-Cost, Shape-Changing Displays Using Electrostatically Inflated Mylar Sheets

We describe how sheets of metalized mylar can be cut and then “inflated” into complex 3D forms with electrostatic charge for use in digitally-controlled, shape-changing displays. This is achieved by placing and nesting various cuts, slits and holes such that mylar elements repel from one another to reach an equilibriu…

PneuMesh: Pneumatic-driven Truss-based Shape Changing System

From cross-sea bridges to large-scale installations, truss structures have been known for their structural stability and shape complexity. In addition to the advantages of static trusses, truss structure has a large degree of freedom to change shape when equipped with rotatable joints and retractable beams. However, i…

FlexTruss: A Computational Threading Method for Multi-material, Multi-form and Multi-use Prototyping

3D printing, as a rapid prototyping technique, usually fabricates objects that are difficult to modify physically. This paper presents FlexTruss, a design and construction pipeline based on the assembly of modularized truss-shaped objects fabricated with conventional 3D printers and assembled by threading. To create a…

SimuLearn: Fast and Accurate Simulator to Support Morphing Materials Design and Workflows

Morphing materials allow us to create new modalities of interaction and fabrication by leveraging the materials’ dynamic behaviors. Yet, despite the ongoing rapid growth of computational tools within this realm, current developments are bottlenecked by the lack of an effective simulation method. As a result, existing…

E-seed: Shape-Changing Interfaces that Self Drill

As sensors and interactive devices become ubiquitous and transition outdoors and into the wild, we are met with the challenge of mass deployment and actuation. We present Eseed, a biomimetic platform that consumes little power to deploy, harvests energy from nature to install, and functions autonomously in the field.…

Geodesy: Self-rising 2.5D Tiles by Printing along 2D Geodesic Closed Path

Thermoplastic and Fused Deposition Modeling (FDM) based 4D printing are rapidly expanding to allow for space- and material-saving 2D printed sheets morphing into 3D shapes when heated. However, to our knowledge, all the known examples are either origami-based models with obvious folding hinges, or beam-based models wi…

Self-healing UI: Mechanically and Electrically Self-healing Materials for Sensing and Actuation Interfaces

Living things in nature have long been utilizing the ability to “heal” their wounds on the soft bodies to survive in the outer environment. In order to impart this self-healing property to our daily life interface, we propose Self-healing UI, a soft-bodied interface that can intrinsically self-heal damages without ext…

Thermorph: Democratizing 4D Printing of Self-Folding Materials and Interfaces

We develop a novel method printing complex self-folding geometries. We demonstrated that with a desktop fused deposition modeling (FDM) 3D printer, off-the-shelf printing filaments and a design editor, we can print flat thermoplastic composites and trigger them to self-fold into 3D with arbitrary bending angles. This…

Printed Paper Actuator: A Low-cost Reversible Actuation and Sensing Method for Shape Changing Interfaces

We present a printed paper actuator as a low cost, reversible and electrical actuation and sensing method. This is a novel but easily accessible enabling technology that expands upon the library of actuation-sensing materials in HCI. By integrating three physical phenomena, including the bilayer bending actuation, the…

4DMesh: 4D Printing Morphing Non-Developable Mesh Surfaces

We present 4DMesh, a method of combining shrinking and bending thermoplastic actuators with customized geometric algorithms to 4D print and morph centimeter- to meter-sized functional non-developable surfaces. We will share two end-to-end inverse design algorithms. With our tools, users can input CAD models of target…
