3D Printing Soap: Exploring New Biodegrdable Materials and Creative Possibilities

Soap is a colorful, DIY-friendly, and biodegradable material with potential beyond cleaning. This paper introduces a range of recipes for 3D-printable soap enhanced with additives that enable customization of color, scent, conductivity, and environmental responsiveness. To support fabrication, we designed a low-cost 3…

Circuit2Yarn: From Planar Circuits to Electronic Yarns for Textile-based Interactions

Smart yarns hold the potential to transform everyday textiles into functional platforms, yet current methods remain constrained. These include conductive yarns, made from silver or stainless steel, which retain the feel of conventional yarns but offer limited functions, and PCB-based solutions, which add capability at…

DissolvPCB: Fully Recyclable 3D-Printed Electronics with Liquid Metal Conductors and PVA Substrates

We introduce DissolvPCB, an electronic prototyping technique for fabricating fully recyclable printed circuit board assemblies (PCBAs) using affordable FDM 3D printing, with polyvinyl alcohol (PVA) as a water-soluble substrate and eutectic gallium-indium (EGaIn) as the conductive material. When obsolete, the PCBA ca…

Exergy: A Toolkit to Simplify Creative Applications of Wind Energy Harvesting

Energy harvesting reduces the burden of power source maintenance and promises to make computing systems genuinely ubiquitous. Researchers have made inroads in this area, but their novel energy harvesting materials and fabrication techniques remain inaccessible to the general maker communities. Therefore, this paper ai…

Privacy vs. Awareness: Relieving the Tension between Older Adults and Adult Children When Sharing In-home Activity Data

While aging adults frequently prefer to "age in place", their children can worry about their well-being, especially when they live at a distance. Many in-home systems are designed to monitor the real-time status of seniors at home and provide information to their adult children. However, we observed that the needs and…

SwellSense: Creating 2.5D interactions with micro-capsule paper

In this paper, we propose SwellSense, a fabrication technique to screen print stretchable circuits onto a special micro-capsule paper, creating localized swelling patterns with sensing capabilities. This simple technique will allow users to create a wide range of paper-based tactile interactive devices, which are most…

Functional Destruction: Utilizing sustainable materials' physical transiency for electronics applications

Today's electronics are manufactured to provide stable functionality and fixed physical forms optimized for reliable operation over long periods and repeated use. However, even when applications don't call for such robustness, the permanency of these electronics comes with environmental consequences. In this paper, we…

PITAS: Sensing and Actuating Embedded Robotic Sheet for Physical Information Communication

This work presents PITAS, a thin-sheet robotic material composed of a reversible phase transition actuating layer and a heating/sensing layer. The synthetic sheet material enables non-expert makers to create shape-changing devices that can locally or remotely convey physical information such as shape, color, texture a…

FlexHaptics: A Design Method for Passive Haptic Inputs Using Planar Compliant Structures

This paper presents FlexHaptics, a design method for creating custom haptic input interfaces. Our approach leverages planar compliant structures whose force-deformation relationship can be altered by adjusting the geometries. Embedded with such structures, a FlexHaptics module exerts a fine-tunable haptic effect (i.e.…

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…
