The labeling of clothing has been popularized for more than a decade using RFID technology, but if the electronic components are woven into the fibers of the clothes, and can be thrown into the washing machine? Primo1D, a startup based in Grenoble, France, is developing such a technology. A few days ago, Google announced a development project, Project Jacquard, to expand production of a smart fiber. Founded in August 2013, Primo1D is an independent company of the CEA-LeTI, a microelectronics research unit of the French Atomic Energy Commission (CEA); this startup has effectively put "wearable devices" The concept is pushed to new heights.
Today's smart wearable wearable devices are usually made up of special parts (pockets) that can be placed together in electronic clothing, and can be removed; the electronic components developed by Primo1D are RFID chips. Directly link two sets of wires (acting as antennas) and spun into yarns; therefore, in this E-Thread fiber, there is a passive RFID (Radio Frequency Identification) tag that does not require a power supply, and can be applied to any standard. UHF RFID reader.

Primo1D CEO Emmanuel Arene said in an interview that he expects the company to generate its first revenue in 2016; the initial application of its E-Thread technology will be sheets and textiles used by medical institutions and hotels/hotels. This type of fabric requires professional cleaning procedures and inventory management. Primo1D is not a chip company, its innovative technology is basically a special process for the development of microelectronics packaging; the company's RFID chip supplier is the American manufacturer Impinj. “We procured 8-inch wafer-level chips from Impinj and added some process steps to the wafers, which made the packaged chips more durable;†Arene explained that the process was first in the clean room of CEA-LeTI. Developed.
It is understood that Primo1D's E-Thread technology itself, process and some applications, a total of 20 patents; Primo 1D has exclusive use of the technology, and the patent owner belongs to CEA-LeTI. Primo1D is currently working with some textile companies. Arene added that once RFID chips and antennas can be integrated with textile yarns (including cotton, polyester, wool or plastic), textile manufacturers can weave them into a variety of clothing, bed sheets, luxury goods or It is an industrial product; and the application of the technology to the textile industry as much as possible will be the key to expanding the market for this new technology.
The traditional RFID tag solution (pictured above) requires two steps to connect to the external conductor: first the internal component is to be linked to the outer cover (wire), then the outer cover is connected to the outer conductor; but E-Thread technology (below) ), an innovative microelectronic packaging technology that requires only one step—allowing the chip to directly link two sets of conductors that act as antennas, power supplies, or data buses. Since this technology may read personal information without my permission, this technology may also infringe on personal privacy concerns.
