Alternatively and/or additionally, one, several or all textile layers comprise one or several electrical conductor tracks. An electronic component is understood to mean, for example, an electrical or electronic unit, in particular a functional unit, in particular a connection unit, an energy supply unit, a lighting unit, a sensor unit, a visual, acoustic and/or optical output unit, in particular a signal unit, a communication unit, for example a microphone or a loudspeaker . Furthermore, the electronic component can, for example, form a semiconductor component, for example a rectifier, an amplifier element, a storage element, a light-emitting element, a sensor element or another element that appears sensible to a person skilled in the art. In particular, electrode surfaces form an electronic component, the electrode surfaces being arranged and/or designed, for example, to construct a capacitive sensor. In particular, the electrode surfaces are formed by full-surface embroidery with a conductive yarn, by printing with conductive inks or patties, or by laminating conductive textiles or foils. The electrical conductor track is designed in particular as an electrical connection. For example, the electrical conductor track is designed to connect one or more electronic components.

Die Textillagen, insbesondere umfassend die Elektronikkomponente, Elektronikkomponenten, elektrische Leiterbahn und/oder elektrische Leiterbahnen, sind geschichtet, insbesondere gestapelt, angeordnet, wobei das Stapeln und/oder das Schichten in eine Schichtungsrichtung erfolgt und/oder diese vorgibt. Die Schichtungsrichtung ist insbesondere von einer ersten Schicht, beispielsweise einer untersten Elektroniklage zu einer obersten Schicht, insbesondere einer obersten Elektroniklage orientiert. Insbesondere definiert und/oder ergibt sich aus der Schichtungsrichtung eine Höhe der Textilvorrichtung und/oder der gestapelten Textillagen. Mit anderen Worten bilden die Textillagen, bzw. Elektroniklagen, einen Sandwich-Aufbau. Die textile Elektronikvorrichtung umfasst mindestens zwei, insbesondere mindestens zwei und im Speziellen mindestens zehn Textillagen. The textile layers, in particular comprising the electronic component, electronic components, electrical conductor track and/or electrical conductor tracks, are arranged in layers, in particular stacked, with the stacking and/or the layers taking place in a layering direction and/or specifying this direction. The layering direction is oriented in particular from a first layer, for example a bottom electronics layer, to a top layer, in particular a top electronics layer. In particular, the stacking direction defines and/or results in a height of the textile device and/or the stacked textile layers.

Die textile Elektronikvorrichtung umfasst Sticklinien, wobei die Sticklinien auf einem leitfähigen Fadenmaterial, insbesondere leitfähigen Garn basieren. Die Sticklinien sind durch ein Stickverfahren aufgebracht. Die Sticklinien können krummlinig oder geradlinig, insbesondere verzweigt, ausgebildet sein. Die Anzahl an Sticklinien verlaufend in und/oder durch die Textillagen nimmt für die Textillagen in Schichtungsrichtung ab. Dabei verläuft eine Sticklinie insbesondere durch die Textillagen bzw. Elektroniklagen unter ihnen, wobei Textillagen und/oder Elektroniklagen über ihnen die Sticklinie nicht umfassen und/oder kreuzen. Beispielsweise verläuft eine Sticklinie von einer mittigen Textillage durch die darunterliegenden, wobei die darüber liegenden von der Sticklinie frei sind. Der Erfindung liegt die Überlegung zugrunde, Sticklinien so anzubringen, dass nur die darunterliegenden Schichten durch Sticken verbunden und/oder gekreuzt werden. Beispielsweise kommen pro Textillage bzw. Elektroniklage Sticklinien hinzu, so dass für die unterste Schicht eine erste Anzahl an Sticklinien, für die zweite eine zweite Anzahl von Sticklinien und für die dritte eine dritte Anzahl von drei Sticklinien ergibt, wobei erste Anzahl größer zweite Anzahl und zweite Anzahl größer dritte Anzahl gilt. The textile electronic device includes embroidery lines, the embroidery lines being based on a conductive thread material, in particular a conductive yarn. The embroidery lines are applied using an embroidery process. The embroidery lines can be curvilinear or straight, in particular branched.

In this case, an embroidery line runs in particular through the textile layers or electronic layers below them, with textile layers and/or electronic layers above them not encompassing and/or crossing the embroidery line. For example, an embroidery line runs from a central textile layer through the layers below, with the layers above being free of the embroidery line. The invention is based on the idea of attaching embroidery lines in such a way that only the underlying layers are connected and/or crossed by embroidery. For example, embroidery lines are added per textile layer or electronic layer, so that for the bottom layer a first number of embroidery lines, for the second a second number of embroidery lines and for the third one third number of three embroidery lines, whereby the first number is greater than the second number and the second number is greater than the third number.
Die Erfindung erlaubt es, einen mehrschichtigen Aufbau einer textilen Elektronikvorrichtung bereitzustellen, bei dem Sticklinien aus leitfähigem Fadenmaterial nur darunterliegende Schichten elektrisch verbinden und darüber liegende frei lässt, sodass auf den Ebenen unterschiedliche Komponenten angeordnet werden können, insbesondere verbunden, ohne dass Sticklinienkreuzungen und somit elektrische Kurzschlüsse oder Überbrückungen entstehen. Insbesondere kann so vermieden werden, dass es zu Kreuzungen von elektrischen Sticklinien kommt, die auf unterschiedlichen Lagen angeordnet sind. The invention makes it possible to provide a multi-layer structure of a textile electronic device in which embroidery lines made of conductive thread material electrically connect only layers underneath and leave those above exposed so that different components can be arranged on the levels, in particular connected, without embroidery lines crossing and thus electrical short circuits or bridging arise. In particular, crossings of electric embroidery lines that are arranged on different layers can be avoided in this way.
Insbesondere ist es vorgesehen, dass die elektrischen Leiterbahnen in und/oder auf der Textillage angeordnet ist. Die elektrische Leiterbahn ist vorzugsweise als eine Sticklinie ausgebildet. Beispielsweise ist die elektrische Leiterbahn in einem textilen Verfahren, insbesondere Sticken, mit dem leitfähigen Fadenmaterial aufgebracht. Bedingt durch den Stickprozess kann im Speziellen ein Teil der Sticklinie, die die elektrischen Leiterbahnen bildet, durch andere darunterliegende Textillagen verlaufen. In particular, it is provided that the electrical conductor tracks are arranged in and/or on the textile layer. The electrical conductor track is preferably designed as an embroidery line. For example, the electrical conductor track is applied with the conductive thread material in a textile process, in particular embroidery. Due to the embroidery process, part of the embroidery line, which forms the electrical conductor tracks, can run through other underlying textile layers.
Insbesondere sind Elektronikkomponenten innerhalb einer Textillage durch die elektrischen Leiterbahnen verbunden, insbesondere durch die Sticklinien aus dem leitfähigen Fadenmaterial. In particular, electronic components within a textile layer are connected by the electrical conductor tracks, in particular by the embroidery lines made of the conductive thread material.
Besonders bevorzugt ist es, dass die textile Elektronikvorrichtung mindestens eine elektronische Durchkontaktierung aufweist. Die elektronische Durchkontaktierung ist insbesondere eine elektrische Verbindung zwischen mindestens zwei Textillagen, insbesondere mindestens zwei Elektroniklagen. Beispielsweise umfassen die Textillagen, welche durch die elektrische Durchkontaktierung verbunden werden, Kontaktierungspunkte, wobei die Durchkontaktierung bzw. elektrische Verbindung durch die Kontaktierungspunkte verläuft. Insbesondere ist die Durchkontaktierung als Sticklinie ausgebildet und/oder von einer Sticklinie gebildet. Beispielsweise wird zur Durchkontaktierung eine Sticklinie durch die Kontaktierungspunkte vorgesehen. Die Sticklinie zur Durchkontaktierung ist aus dem leitfähigen Fadenmaterial ausgebildet. Die Durchkontaktierung bildet insbesondere eine Spezialform einer elektrischen Leiterbahn, wobei diese Spezialform der elektrischen Leiterbahn über mindestens zwei Ebenen elektrisch verbindet. It is particularly preferred that the textile electronic device has at least one electronic through-connection. The electronic through-connection is in particular an electrical connection between at least two textile layers, in particular at least two electronic layers. For example, the textile layers, which are connected by the electrical through-connection, include contacting points, with the through-connection or electrical connection running through the contacting points. In particular, the via is designed as an embroidery line and/or is formed by an embroidery line. For example, an embroidery line is provided through the contacting points for through-plating. The embroidery line for via is formed from the conductive thread material. The plated-through hole forms, in particular, a special form of an electrical conductor track, with this special form of the electrical conductor track being electrically connected over at least two levels.
Dieser Ausgestaltung liegt die Überlegung zugrunde, dass so eine textile Elektronikvorrichtung bereitgestellt werden kann, welche elektrische Leiterbahnen innerhalb einer Textillage sowie elektrische Durchkontaktierung über mehrere Textillagen in einem Arbeitsschritt und/oder mittels einem Arbeitsverfahren, beispielsweise Sticken, erzeugen kann. This configuration is based on the idea that a textile electronic device can be provided that can produce electrical conductor tracks within a textile layer and electrical through-contacting across multiple textile layers in one work step and/or by means of a work process, for example embroidery.
Insbesondere bildet die textile Elektronikvorrichtung ein elektronisches Funktionsmodul, insbesondere ein Funktionsmodul mit einer elektronischen Schaltung und/oder welches eine elektronische Schaltung bildet. Das elektronische Funktionsmodul, bzw. die textile Elektronikvorrichtung umfasst eine Vielzahl an Elektronikkomponenten, insbesondere zum Aufbau der elektronischen Schaltung. Die Elektronikkomponenten sind insbesondere auf mindestens zwei Elektroniklagen, insbesondere Textillagen, verteilt. Dieser Ausgestaltung liegt die Überlegung zugrunde, statt einer großflächigen Elektronikvorrichtung bei der alle Elektronikkomponenten in einer Ebene angeordnet sind, eine textile Elektronikvorrichtung vorzuschlagen, bei der die Elektronikkomponenten auf mehrere Elektroniklagen verteilt sind und besonders kleinbauend realisiert werden kann. Insbesondere ist die elektronische Schaltung auf mindestens zwei Elektroniklagen verteilt. Mit anderen Worten ist die elektronische Schaltung bzw. der Signalverlauf, Datenverlauf und/oder elektrische Verbindungen über mehrere Elektroniklagen verteilt. In particular, the textile electronic device forms an electronic functional module, in particular a functional module with an electronic circuit and/or which forms an electronic circuit. The electronic function module, or the textile electronic device, comprises a large number of electronic components, in particular for the construction of the electronic circuit. The electronic components are in particular distributed over at least two electronic layers, in particular textile layers. This configuration is based on the idea of proposing a textile electronic device, in which the electronic components are distributed over several electronic layers and which can be implemented in a particularly compact manner, instead of a large-area electronic device in which all the electronic components are arranged in one plane. In particular, the electronic circuit is distributed over at least two electronic layers. In other words, the electronic circuit or the signal curve, data curve and/or electrical connections are distributed over a number of electronic layers.
Besonders bevorzugt ist es, dass die textile Lage ein Gewirk, ein Gestrick, ein Gewebe oder ein Vlies bildet. Insbesondere ist die Textillage als eine flächige Textillage bzw. flächiger Textilabschnitt ausgebildet. Die Textillage kann insbesondere zumindest partiell metallisch beschichtet ausgebildet sein. It is particularly preferred that the textile layer forms a knitted fabric, a knitted fabric, a woven fabric or a fleece. In particular, the textile layer is designed as a flat textile layer or flat textile section. The textile layer can in particular be at least partially metallically coated.
Insbesondere ist es vorgesehen, dass das leitfähige Fadenmaterial als ein metallbeschichtetes Garn ausgebildet ist, vorzugsweise metallbeschichtetes Polyamidgarn und im Speziellen ein silberbeschichtetes Garn. Das metallbeschichtete Garn kann auf einem Naturgarn basieren oder auf einem Kunststoffgarn. In particular, it is envisaged that the conductive thread material is in the form of a metal-coated yarn, preferably metal-coated polyamide yarn and in particular a silver-coated yarn. That metal-coated yarn can be based on a natural yarn or on a synthetic yarn.
Eine Ausgestaltung der Erfindung sieht vor, dass mindestens zwei Elektroniklagen, insbesondere Textillagen, im Speziellen alle Elektroniklagen und/oder Textillagen, stoffschlüssig verbunden sind. Die stoffschlüssige Verbindung dient insbesondere dem Verhindern eines Verschiebens von Elektroniklagen zueinander. Die stoffschlüssige Verbindung ist beispielsweise als eine Laminierung ausgebildet. Beispielsweise ist hierzu eine Laminierfolie zwischen zwei Elektroniklagen, insbesondere vor Anbringung der Leiterbahnen in der Ebene und/oder der Durchkontaktierung, eingelegt und anschließend laminiert. Das Laminieren kann insbesondere unter Verwendung eines Schmelzgarns ausgeführt sein. Alternativ und/oder ergänzend ist die stoffschlüssige Verbindung der Elektroniklagen als ein Verkleben, insbesondere ein vollflächiges oder punktuelles Verkleben, ausgebildet. An embodiment of the invention provides that at least two electronic layers, in particular textile layers, in particular all electronic layers and/or textile layers, are materially bonded. The material connection is used in particular to prevent electronic layers from shifting relative to one another. The material connection is formed, for example, as a lamination. For this purpose, for example, a laminating film is inserted between two electronic layers, in particular before the conductor tracks are attached in the plane and/or the plated-through hole, and then laminated. The lamination can be carried out in particular using a melted yarn. As an alternative and/or in addition, the integral connection of the electronic layers is in the form of an adhesive bond, in particular an adhesive bond over the entire surface or at certain points.
Im Speziellen ist es vorgesehen, dass mindestens zwei Elektroniklagen und/oder mindestens zwei Textillagen, im Speziellen alle Lagen, mittels einer Verbindungssticklinie und/oder eine Mehrzahl an Verbindungsstücklinien verbunden sind. Die Verbindungssticklinien sind beispielsweise ähnlich wie bei einer Steppdecke angebracht. Die Verbindungssticklinie basiert insbesondere auf einem nichtleitfähigen Garn, insbesondere ist die Verbindungsstücklinie nach Anbringung aller Leiterbahnen angeordnet und/oder eingebracht. In particular, it is provided that at least two electronic layers and/or at least two textile layers, in particular all layers, are connected by means of a connecting embroidery line and/or a plurality of connecting piece lines. For example, the connecting embroidery lines are attached similar to a quilt. The connecting embroidery line is based in particular on a non-conductive thread, in particular the connecting piece line is arranged and/or introduced after all conductor tracks have been attached.
Einen weiteren Gegenstand der Erfindung bildet ein Verfahren zur Herstellung einer Elektronikvorrichtung. Das Verfahren sieht vor, dass Textillagen, umfassend jeweils mindestens eine Elektronikkomponente und/oder eine elektrische Leiterbahn, geschichtet werden, wobei Sticklinien aus einem leitfähigen Fadenmaterial angebracht werden, wobei die Anzahl an Sticklinien verlaufend durch die Textillagen in eine Schichtungsrichtung abnimmt. Beispielsweise wird hierzu in einem ersten Schritt auf den Textillagen vor Einbringung der Leiterbahnen und/oder der Durchkontaktierung die Elektronikkomponenten aufgebracht, beispielsweise aufgeklebt oder aufgenäht. Der Aufbau der textilen Elektronikvorrichtung erfolgt insbesondere schrittweise. Zunächst wird eine in Schichtungsrichtung eine unterste Textillage und/oder Elektroniklage angeordnet und die in diese Textillage benötigten Leiterbahnen durch Sticken mit dem leitfähigen Fadenmaterial angebracht. Die so eingebrachten Sticklinien erstrecken sich nur über diese Lage. In einem nächsten Schritt wird über die unterste Textillage eine weitere Textillage und/oder Elektroniklage aufgelegt. Die Leiterbahnen, insbesondere auch Durchkontaktierungspunkte, werden anschließend durch Sticken aufgebracht.A further subject matter of the invention is a method for producing an electronic device. The method provides that textile layers, each comprising at least one electronic component and/or an electrical conductor, are layered, embroidery lines made of a conductive thread material being applied, the number of embroidery lines running through the textile layers decreasing in a layering direction. For example, in a first step, the electronic components are applied, for example glued or sewn, to the textile layers before the conductor tracks and/or the through-contacting are introduced. The construction of the textile electronic device takes place step by step. First, in the layering direction, a bottom textile layer and/or Arranged electronics layer and attached the conductor tracks required in this textile layer by embroidering with the conductive thread material. The embroidery lines introduced in this way only extend over this layer. In a next step, a further textile layer and/or electronic layer is placed over the bottom textile layer. The conductor tracks, in particular also via points, are then applied by embroidering.
Die so eingebrachten Sticklinien, welche die Leiterbahnen in dieser Lage bilden und/oder Durchkontaktierungen zwischen den beiden Textillagen ausbilden, erstrecken sich über die beiden Textillagen. Anschließend kann eine weitere Textillage aufgelegt und Leiterbahnen mit dem leitfähigen Garen gestickt werden, wobei sich diese Sticklinien nun über die drei Lagen erstrecken. Dies kann bis zum Erreichen der gewünschten Lagenanzahl und/oder Unterbringung aller Elektronikkomponenten fortgesetzt werden. Vorzugsweise werden in einem ersten Verfahrensschritt auf eine einzige, erste Textillage Sticklinien aus dem leitfähigen Fadenmaterial aufgebracht und in einem anschließenden zweiten Verfahrensschritt nach Auflegen einer zweiten Textillage auf die erste Textillage Sticklinien aus dem leitfähigen Fadenmaterial auf die erste und die zweite Textillage hindurch aufgebracht. The embroidery lines introduced in this way, which form the conductor tracks in this layer and/or form vias between the two textile layers, extend over the two textile layers. Another layer of textile can then be placed on top and conductor tracks can be embroidered with the conductive stitch, with these embroidery lines now extending over the three layers. This can be continued until the desired number of layers and/or placement of all electronic components is achieved. Preferably, in a first method step, embroidery lines made of the conductive thread material are applied to a single, first textile layer, and in a subsequent second method step, after a second textile layer has been placed on the first textile layer, embroidery lines made of the conductive thread material are applied to the first and second textile layers.

The electrical connections can extend within an electronics layer 2a, 2b and form electrical conductor tracks and/or relate to different layers and connect them electrically and form a so-called via 5. The textile electronic device 1 provides that the electrical conductor tracks 4 and the plated-through hole 5 were obtained by a common working method, in this case embroidering, the embroidering being carried out with a conductive thread material 6 .

Durch Sticken mit dem leitfähigen Fadenmaterial 6 wird eine Sticklinie erzeugt, die die elektrischen Leiterbahnen 4 bildet. Ferner ist eine elektrische Durchkontaktierung 8 vorgesehen, die zur elektrischen Kontaktierung und Verbindung mit einer darauf anzuordnenden Elektroniklage 2b ausgebildet ist. Hierzu weist die Elektroniklage 2b ebenso eine Kontaktierung auf, durch die mit dem Fadenmaterial 6 in einem zweiten Schritt gestickt wird und so die Durchkontaktierung 8 hergestellt wird. Insbesondere wird zwischen dem ersten Schritt und im zweiten Schritt beispielsweise eine Laminierfolie im späteren Prozessschritt des Laminierens eingelegt. FIG. 2a shows a first electronics layer 2a, in particular the bottom electronics layer 2a. The electronics layer 2a comprises a textile section as a textile layer and an electronics component 3a and 3b which are connected by means of an electrical conductor track 4 . The electronics layer 2a is shown here in a first step, in which the electronics components 3a, 3b are applied to the textile layer 7, for example stapled or glued. By embroidering with the conductive thread material 6, an embroidered line is produced, which forms the electrical conductor tracks 4. Furthermore, an electrical via 8 is provided, which is designed for electrical contacting and connection to an electronics layer 2b to be arranged thereon. For this purpose, the electronics layer 2b also has a contact, through which the thread material 6 is embroidered in a second step and the through-connection 8 is thus produced. In particular, between the first step and the second step, for example a laminating film is inserted in the later process step of lamination.
Figur 2b zeigt die Elektroniklage 2a aus Figur 2a und eine darüber angeordnete Elektroniklage 2b, welche ebenso eine Textillage 7 sowie Elektronikkomponenten 3c und 3d umfasst. Ferner werden in einem Arbeitsschritt durch Sticken Sticklinien aus dem leitfähigen Fadenmaterial 6 als Leiterbahn 4 generiert, welche in der ersten und zweiten Elektronikebene 2a, 2b verlaufen. Ferner wird zwischen den Kontaktierungspunkten der zweiten und ersten Elektronikebene 2a, 2b eine Durchkontaktierung 8 erzeugt.
