Faser mit integriertem elektronischem Bauteil, elektronisches Gewebe, Herstellungsverfahren und Verwendung dazuFiber with integrated electronic component, electronic fabric, manufacturing process and use therefor
Die Erfindung betrifft das neue Gebiet der "wearable electro- nics" insbesondere ein in eine Faser integriertes elektronisches Bauteil, ein Gewebe für ein Textil mit zumindest einer Faser mit integriertem elektronischem Bauteil, ein Herstel- lungsverfahren und Verwendungen dazu.The invention relates to the new field of "wearable electronics", in particular an electronic component integrated in a fiber, a fabric for a textile with at least one fiber with an integrated electronic component, a production method and uses therefor.
Gewebe mit einem integrierten elektronischen Bauteil ist bislang praktisch unbekannt. Erste Ansätze beruhen darauf, dass man herkömmliche, siliziumhaltige Halbleiter-Elektronik oder einfache metallische Leiterfäden ins Gewebe einbaut. Nachteilig daran ist, dass die Fasern der Gewebe selbst keine Träger elektronischer Bauteile sind.So far, tissue with an integrated electronic component is practically unknown. The first approaches are based on the fact that conventional silicon-containing semiconductor electronics or simple metallic conductor threads are built into the fabric. The disadvantage of this is that the fibers of the fabric themselves are not carriers of electronic components.
Aufgabe der Erfindung ist es, eine Faser zu schaffen, in der ein elektronisches Bauteil integriert ist.The object of the invention is to create a fiber in which an electronic component is integrated.
Gegenstand der Erfindung ist eine Faser mit zumindest einem integriertem elektronischem Bauteil, wobei zumindest ein Teil der Faser Leiterbahn, isolierende oder halbleitende Schicht des Bauteils und/oder ein sonstiges Element des Bauteils ist. Weiterhin ist Gegenstand der Erfindung ein Gewebe, das zumindest eine Faser mit einem integrierten elektronischen Bauteil umfasst. Schließlich ist Gegenstand der Erfindung die Herstellung eines elektronischen und/oder intelligenten Gewebes durch Verknüpfung einer Faser mit integriertem elektronischem Bauteil mit zumindest einer weiteren Faser, die gleich oder ungleich der ersten Faser sein kann. Schließlich ist Gegenstand der Erfindung die Verwendung von elektronischem Gewebe in Kleidung, Möbel, Einrichtung und/oder sonstigen Textilien.The invention relates to a fiber with at least one integrated electronic component, at least part of the fiber being the conductor track, insulating or semiconducting layer of the component and / or another element of the component. The invention furthermore relates to a fabric which comprises at least one fiber with an integrated electronic component. Finally, the subject of the invention is the production of an electronic and / or intelligent fabric by linking a fiber with an integrated electronic component to at least one further fiber, which can be the same or different from the first fiber. Finally, the subject of the invention is the use of electronic tissue in clothing, furniture, furnishings and / or other textiles.

Zur Einbettung und/oder Ummantelung der Elektronik geeignete textile Fasern sind sämtliche in der Textilindustrie gängigen Chemiefasern wie Polyacryl-, Polyamid-, Polyester-, Elastan-, Viskose-, Acetat-Fasern, sowie Polytetrafluorethylenfasern (PTFE) und sämtliche unter dem Sammelbegriff Mikrofasern gängige FasernTextile fibers suitable for embedding and / or sheathing the electronics are all chemical fibers common in the textile industry such as polyacrylic, polyamide, polyester, elastane, viscose, acetate fibers, as well as polytetrafluoroethylene fibers (PTFE) and all common under the generic term microfibers fibers
Bei der Herstellung des Gewebes wird durch entsprechende Verbindung oder Auftrennung an den Kreuzungspunkten der Fäden im Gewebe eine oder mehrere geeignete Verknüpfungen hergestellt oder unterbrochen, so dass eine komplexe elektronische Schaltung realisiert werden kann. Im einfachsten Fall wird ein Leiterbahnengeflecht erzeugt, das beispielsweise eine in einem Textil integrierte Spule darstellt.During the production of the fabric, one or more suitable connections are made or interrupted by a corresponding connection or separation at the crossing points of the threads in the fabric, so that a complex electronic circuit can be implemented. In the simplest case, a conductor track braid is produced which, for example, represents a coil integrated in a textile.
Das zumindest eine Bauteil ist in der Faser durch geeigneten Schichtaufbau integriert. Dazu sind die Fasern so ausgelegt, dass die Bauteile durch eine integrierte Faser oder eine entsprechend leitfähige Oberfläche miteinander elektrisch verbunden sind. Im Folgenden wird die Erfindung anhand dreier Figuren, die Ausführungsformen der Erfindung darstellen, näher erläutert.The at least one component is integrated in the fiber by means of a suitable layer structure. For this purpose, the fibers are designed so that the components are electrically connected to one another by an integrated fiber or a correspondingly conductive surface. The invention is explained in more detail below with the aid of three figures which represent embodiments of the invention.
Figur 1 zeigt drei Ausschnitte einer oder mehrerer Fasern mit verschiedenen integrierten Bauteilen.Figure 1 shows three sections of one or more fibers with different integrated components.
Figuren 2 und 3 zeigen Beispiele für intelligente Gewebe.Figures 2 and 3 show examples of intelligent tissues.
In Figur 1 sind drei Ausschnitte einer Faser oder drei Fasern gezeigt mit jeweils einem anderen Bauteil integriert.In Figure 1, three sections of a fiber or three fibers are shown, each with a different component integrated.
Das Teilbild A) zeigt einen schematischen Aufbau eines Widerstands, der in eine Faser integriert ist. Zu sehen ist die Gewebefaser 1, die eine leitfähige Faser 2 ummantelt, wobei die gut leitfähige Faser 2 verbunden ist mit einer schlechter leitfähigen Faser (im Bild als eine Verdickung dargestellt) in Form eines Widerstands 3.The partial picture A) shows a schematic structure of a resistor which is integrated in a fiber. What can be seen is the fabric fiber 1, which encases a conductive fiber 2, the highly conductive fiber 2 being connected to a poorly conductive fiber (shown in the figure as a thickening) in the form of a resistor 3.
Als Teilbild B) ist der schematische Aufbau eines Kondensators und/oder einer Diode in einer Faser integriert gezeigt. Zu sehen ist wieder die Gewebefaser 1, die zwei gut leitfähige Fasern 2 ummantelt. In der Mitte ist ein Bereich mit überlappenden Enden 4 zu erkennen, in dem die beiden Enden der integrierten gut leitfähigen Fasern sich überlappen. Die ü- berlappenden Enden 4 sind im Fall eines Kondensators gegeneinander isoliert und können damit als Kondensator wirken. Im Fall einer Diode ist zwischen den beiden leitfähigen Fasern ein System mit halbleitenden Schichten integriert, so dass dieser Aufbau als Diode wirkt. Dies kann natürlich auch eine Leuchtdiode sein.Part B) shows the schematic structure of a capacitor and / or a diode integrated in a fiber. The fabric fiber 1, which encases two highly conductive fibers 2, can be seen again. An area with overlapping ends 4 can be seen in the middle, in which the two ends of the integrated, highly conductive fibers overlap. In the case of a capacitor, the overlapping ends 4 are insulated from one another and can thus act as a capacitor. In the case of a diode, a system with semiconducting layers is integrated between the two conductive fibers, so that this structure acts as a diode. Of course, this can also be a light emitting diode.
Als Teilbild C) ist schließlich in Figur 1 ein Transistor, der in einer Faser realisiert ist, gezeigt. Beispielsweise kann es sich dabei um einen organischen Feld-Effekt-Transistor handeln. Wieder ist außen die Gewebefaser 1 zu erkennen, die zumindest zwei gut leitfähige Fasern 2 ummantelt. In ei- nem Bereich 5 aus halbleitendem Material überlappen sich die Enden der gut leitfähigen Fasern und bilden die Source und Drain Elektroden 6 des organischen Feld-Effekt-Transistors. Der Bereich 5 aus halbleitendem Material in das die Elektroden 6 eingebettet sind, wird von leitendem Material als Gate Elektrode 7 umgeben. Dabei ist die Gateelektrode noch durch eine isolierende Schicht von dem halbleitenden Material getrennt. Die Gateelektrode kann ebenso gut die Außenfläche also die Faseroberfläche sein.Finally, a transistor, which is implemented in a fiber, is shown in FIG. 1 as partial image C). For example, it can be an organic field-effect transistor. Again, the fabric fiber 1 can be seen on the outside, which sheathes at least two highly conductive fibers 2. In a In a region 5 made of semiconducting material, the ends of the highly conductive fibers overlap and form the source and drain electrodes 6 of the organic field-effect transistor. The area 5 made of semiconducting material in which the electrodes 6 are embedded is surrounded by conductive material as the gate electrode 7. The gate electrode is still separated from the semiconducting material by an insulating layer. The gate electrode can just as well be the outer surface, ie the fiber surface.
Figur 2 zeigt einen Ausschnitt aus einem intelligentem Gewebe. Zu sehen sind die beiden Gewebefäden 8 die sich kreuzen. Beide Gewebefäden haben ein integriertes elektronisches Bauteil 9 mit einer gut leitfähigen Faser 2. Am Kreuzungspunkt 10 ist eine Verbindung vorgesehen, mit der eine Leitung von der einen Faser zu der anderen gebildet wird.Figure 2 shows a section of an intelligent tissue. You can see the two fabric threads 8 that cross. Both fabric threads have an integrated electronic component 9 with a highly conductive fiber 2. At the crossing point 10, a connection is provided with which a line is formed from one fiber to the other.
Figur 3 schließlich zeigt eine Realisierung einer komplexen Schaltung durch ein intelligentes Gewebe mit mehreren Fasern 11, die jeweils integrierte elektronische Bauteile 12 haben, und die an verschiedenen Kreuzungspunkten 13 miteinander verknüpft/verbunden sind.FIG. 3 finally shows a realization of a complex circuit by means of an intelligent fabric with a plurality of fibers 11, each of which has integrated electronic components 12, and which are linked / connected to one another at different crossing points 13.
Durch die Erfindung wird erstmals textiles Gewebe vorge- stellt, in dem elektronische Bauteile in den Fasern des Gewebes selbst integriert sind. Die Fasern werden dabei beispielsweise als leitende, halbleitende oder isolierende Elemente der Bauteile genutzt. The invention for the first time introduces textile fabric in which electronic components are integrated in the fibers of the fabric itself. The fibers are used, for example, as conductive, semi-conductive or insulating elements of the components.
