The invention relates to a method for determining a functional area of an electronic textile (100;200). The electronic textile comprises a textile substrate having a first plurality of conductors (108a-b;202a-d), a second plurality of conductors (104a-c;204a-d), and a plurality of capacitors (112;212a-p), each capacitor comprising a conductor from the first plurality of conductors (108a-b;202a-d) and a conductor from the second plurality of conductors (104a-c;204a-d), separated by a dielectric (103a), the capacitors (112;212a-p) being distributed across substantially an entire surface of the electronic textile, wherein each capacitor (112;212a-p) has a capacitance of at least 10 pF. The method comprises, for each of the capacitors, the steps of (a) applying (301) a voltage between the conductor from the first plurality of conductors associated with the capacitor and the conductor from the second plurality of conductors associated with the capacitor, (b) detecting (302) an electrical characteristic indicative of a capacitance of the capacitor, (c) evaluating (303) the detected electrical characteristic, and (d) determining (304) whether the capacitor is included in the functional area of the electronic textile based on the evaluation. As the method takes advantages of physical characteristics inherent in the electronic textile, such as the capacitors formed between conductors in the electronic textile, no electronic devices need to be arranged on the electronic textile to determine the functional area.

The present invention relates to multilayer textiles for photonic and/or electronic applications. The textile (100) comprises a multilayer structure having a first and a second layer electrically separated by a third layer. The first layer comprises electrically insulating yarns (112) and at least one electrically conductive yarn (111). The second and third layers comprise electrically insulating yarns (132,122) in the weft direction. At least one via-connection is realized between an electrically conductive warp yarn (141) and the at least one electrically conductive weft yarn (111) of the first layer by a tight interweaving. Thus, the present invention provides a flexible textile (100) with robust via-connections.

The present invention relates to a flexible light source (100), adapted to be bent in at least one direction so as to form a line of curvature (Lc), comprising a translucent substrate (104), at least one light emitting diode (102) arranged to emit light into said substrate, and at least one light guide (103) arranged in the path of light between said at least one light emitting diode and said substrate. By placing the LEDs on the rear side of the translucent substrate, heat generated during operation of the LEDs may be transferred to the surrounding atmosphere, thus reducing the risk of overheating. In this way, the LEDs may be operated at temperatures which promote their efficient and long-lasting performance.

The invention relates to a textile carrier comprising a first textile member having a first electrode, and a second member having a second electrode. The first electrode has a direct electrically conductive contact to the second electrode. According to the invention, the direct electrically conductive contact is fixed by a welded connection between the first textile member and the second member. The textile carrier according to the invention can be manufactured by a method that comprises a heating step wherein an area of the first textile member comprising the first electrode is heated to form a liquefied portion of a yarn. The method further comprises a contacting step wherein the area of the first textile member is contacted to the second member to form a direct electrically conductive connection between the first electrode and the second electrode, followed by a fixing step wherein the liquefied portion is solidified to fix the electrically conductive connection between the first electrode and the second electrode. The textile carrier according to the invention can be used to electrically address an electronic component in an electronic textile, particularly in applications that require large-area electronic textiles.

An electronic textile (300;400) comprising a textile substrate (102) having at least a first set of textile substrate conductors (202a-f,203a-e;403) each being arranged to enable electrical connection of an electronic device (209;401) thereto.

The power distributing structure (301;405) has a substantially lower resistivity than each of the textile substrate conductors (202a-f,203a-e;403) to allow for an even distribution among the textile substrate conductors of power from the external power source (210).
