| 192 | Connecting an Electronic Component to an Interactive Textile | US15352194 | 2016-11-15 | US20170325337A1 | 2017-11-09 | Mustafa Emre Karagozler; Ivan Poupyrev; Nan-Wei Gong; Karen Elizabeth Robinson; Patricia Hayes-Danitz; Megan Grant |
| This document describes techniques and apparatuses for connecting an electronic component to an interactive textile. Loose conductive threads of the interactive textile are collected and organized into a ribbon with a pitch that matches a corresponding pitch of connection points of the electronic component. Next, non-conductive material of the conductive threads of the ribbon are stripped to expose the conductive wires of the conductive threads. After stripping the non-conductive material from the conductive threads of the ribbon, the connection points of the electronic component are bonded to the conductive wires of the ribbon. The conductive threads proximate the ribbon are then sealed using a UV-curable or heat-curable epoxy, and the electronic component and the ribbon are encapsulated to the interactive textile with a water-resistant material, such as plastic or polymer. | ||||||
