This tannin-style "wisdom jacket" was created by Google and Levi's, and is mainly supported by Google's Advanced Technology and Projects (ATAP) division. At the 2015 Google I/O conference, the conductive fabric used in this jacket was still in the development stage. By 2016, on the day of the Google I/O conference, Google announced a full cooperation with Levi's, when Paul Dillinger, vice president of product innovation at Levi's. I wore such a jacket on my body. This year, Google and Levi's jointly announced at the Southwestern Texas Southwestern Conference (SXSW) that the smart bike jacket Commuter with touch and motion sensing capabilities is expected to be officially launched this fall.
The smart biker Commuter Trucker Jacket is based on a classic truck jacket with a soft "touch pad" made of conductive fiber, tactile feedback system and sensors in the left cuff. The touchpad on the cuff can be made via Bluetooth and smartphone. Connection, the user can control the music switching, command navigation or pick up the phone by sliding on the cuff; the connecting device can be freely taken out from the jacket, charged by USB, and can be folded and washed like ordinary clothes. The core technology of this jacket - "interactive textiles" is based on Google's leading Project Jacquard technology, the touch fabric technology, which embeds conductive fibers into clothing and turns the garment into the touch layer of electronic devices for remote control. The function of electronic devices.
Project Jacquard technical patent list
The design idea of ​​Google smart bicycle jacket
First, a series of conductive yarns are woven into the fabric in a grid structure to form an interactive fabric with a capacitive touch sensor capable of sensing a touch signal; then the interactive fabric processes the touch input signal into touch data to implement the computer Remote control of terminals such as mobile phones. Due to the flexible nature of textiles, this interactive product can be easily combined with garments, hats, bags and the like to form wearable devices.
Technical analysis (1) Preparation of conductive yarn
The flexible yarn 308 and the conductive wire 306 are interwoven in the conductive yarn by winding to form a conductive core and a cover layer. Usually, a plurality of flexible yarns are wound around the conductive wires, and the conductive wires are wrapped in the flexible yarns, and finally the conductive yarns 208 are produced.
Technical analysis (2) Preparation of interactive fabrics
The conductive yarns are woven into the fabric in a crisscross pattern, forming a grid of conductive yarns on the fabric that enables the fabric to identify the location of the user's gestures on the fabric through the grid.
The fabric containing the conductive yarn is composited by upper and lower layers by sewing, gluing, etc. to form an interactive fabric. Conductive yarns 606 and conductive yarns 608 are woven into both the upper fabric 602 and the lower fabric 604. When the upper and lower layers of fabric are joined together, a capacitive touch sensor 202 capable of detecting a touch input signal is formed between the conductive yarns in the two layers of fabric.
Technical analysis (3) remote connection and control
The flexible yarn wrapped around the conductive wire in the above fabric is removed by laser beam treatment or heat treatment, the conductive wire is exposed, and the electronic component is connected with the exposed conductive wire to realize the electronic component and the interactive fabric. connection.
Remote control of electronic devices by Google interactive fabrics is achieved through collaboration of interactive fabrics and computer devices. The capacitive touch sensor located in the interactive fabric detects the touch position and displacement of the finger in the conductive yarn grid and converts the touch input signal into touch data for transmission to the computer device, thereby realizing control of the related device.
