“…With a growing interest in stretchable interfaces, novel solutions are required to enable custom stretchable circuits. While initial work in this area has demonstrated how to realize stretchable sensors [32,42,44,46,49] and displays [46], recent research has demonstrated a considerably advanced fabrication technique that enables multi-layer stretchable devices including off-the-shelf components [26]. The approach combines silicone casting with laser patterning.…”

This paper introduces LASEC, the first technique for instant do-it-yourself fabrication of circuits with custom stretchability on a conventional laser cutter and in a single pass. The approach is based on integrated cutting and ablation of a two-layer material using parametric design patterns. These patterns enable the designer to customize the desired stretchability of the circuit, to combine stretchable with nonstretchable areas, or to integrate areas of different stretchability. For adding circuits on such stretchable cut patterns, we contribute routing strategies and a real-time routing algorithm. An interactive design tool assists designers by automatically generating patterns and circuits from a high-level specification of the desired interface. The approach is compatible with off-the-shelf materials and can realize transparent interfaces. Several application examples demonstrate the versatility of the novel technique for applications in wearable computing, interactive textiles, and stretchable input devices.

“…In recent years, researchers have explored how to use the fexibility and softness of materials to create interactive objects. Some work creates sensors by mixing soft and conductive materials together such as coating sponges in conductive ink [22], curing a carbon-flled elastomer [37], embedding conductive ink into 3D printing with fexible thermoplastic polyurethane (TPU) [1], and printing TPU and conductive flaments together [31]. Using the same fexible material of TPU, Ion et al print mechanisms composed of metamaterial cells [12].…”

“…SkinMarks [35] and iSkin [34] are 1D compliant skin-worn sensors for touch input. Flexible touch matrices have been created through multi-layer resistive fabric [11,19,25], pressure-sensitive textile optical fibers [22], plastic film over sensing electrodes [21], a piezoresistive elastomer-based soft sensor using electrical impedance tomography [39], embroidery [6,17,40], fabric screen-printing [41]; metal foils [12], and weaving of conductive thread [14,18].…”

ABSTRACTWe introduce I/O Braid, an interactive textile cord with embedded sensing and visual feedback. I/O Braid senses proximity, touch, and twist through a spiraling, repeating braiding topology of touch matrices. This sensing topology is uniquely scalable, requiring only a few sensing lines to cover the whole length of a cord. The same topology allows us to embed fiber optic strands to integrate co-located visual feedback.We provide an overview of the enabling braiding techniques, design considerations, and approaches to gesture detection. These allow us to derive a set of interaction techniques, which we demonstrate with different form factors and capabilities. Our applications illustrate how I/O Braid can invisibly augment everyday objects, such as touch-sensitive headphones and interactive drawstrings on garments, while enabling discoverability and feedback through embedded light sources. ExpressivityWe are interested in extending the I/O Braid gesture set. For example, we plan to investigate support for several of the popular gestures from the elicitation study, such as slide, as they should be possible to recognize using the current architecture. We are also interested in reflectometry [37] to sense the position of a touch on the cord. Combining I/O Braid with near field radio or bioimpedance [23, 24] may
