PROJECT JACQUARD

1

ABSTRACTProject Jacquard is a new Interfacing Technology that makes it possible to weave touch and gesture interactivity into any textile using standard, industrial looms.Everyday objects such as clothes and furniture can be transformed into interactive surfaces. These interactions can be reconfigured at any time.Developers will be able to connect existing apps and services to Jacquard-enabled clothes .

INTRODUCTIONR&D by Google ATAP(Advanced Technology and Projects Group)

Project team lead by Ivan Poupyrev

In partnership with Levi Strauss & Co

Project Jacquard was announced at Google I/O 2015


WHAT IS PROJECT JACQUARD?A platform for embedding sensors & devices in fabrics in ways that seem natural and comfortable.Users can provide input to a mobile phone by touching or stroking the garment in a designated location.Users can receive alerts through vibrations, sounds, or lights in the garments. Novel conductive yarns designed to be woven entirely invisible without affecting the look and feel of the fabric.Can be designed to a variety of colors and textures with designers needs.


BACKGROUND & RELATED WORKAn early exploration of interactivity to clothing using conductive yarns was Musical Jacket developed in 1998 by Margaret Orth at MIT Media Lab.No significant breakthroughs at attempts to design interactive conductive yarns for weaving into textiles at industrial scale. CHALLENGES Battery requirements are critical.Electronics must be flexible and able to survive washing, drying, ironing, and dry cleaning.Combining Hard Electronics and Soft Textiles.


Whats different in Project Jacquard?Conductive yarn can be woven into textiles using standard looms, inexpensively and at scale. Woven textile structures withstand harsh and destructive processes of manufacturing.Jacquard textiles can withstand home washing, ironing and dry cleaning cycles. Electronics & Textiles combined using simple soldering process.Jacquard electronic system is simple, modular and efficient.

JACQUARD YARNThe core technology for developing interactive textiles. Jacquard yarn specificationsConventional look and feel Multiple colors, thicknesses, and materials Electrical conductivity Strength, temperature, chemical resistance Electronics interconnectivity Reliability & SafetyCost and manufacturing at scale


Figure 2. Jacquard yarns are indistinguishablefrom normal yarns

JACQUARD YARN ENGINEERINGTwo structural elements Silk & Conductive Metal Wires.The core of the yarn Several strands of highly conductive thin metal wires braided with 2 strands of silk.This core structure is then over-braided for several reasons.

JACQUARD WEAVING & TEXTILESPractically any texture, image, or visual pattern can be woven.The textile can be rigid or stretchable, flat or woven with depth, bumpy, plush, or with ridges.The interactivity reside in limited locations defined by the needs of the application.

CONNECTIVITY TO ELECTRONICSThe conductive yarn forms a localized, square conductive area, then passes through the fabric, where it floats.Floating Jacquard yarns is connected to electrical interposers by soldering.It is relatively trivial to connect the interposer to any other electronic device.

ConclusionProject Jacquard allows weaving interactive textiles at scale.

Its a possibility that the current work will inspire research in new forms of materials and integration of computation into the everyday objects and environments.

Brings the vision of invisible seamless computing one step closer to the reality.
