Der Anforderung flächiger, skalierbarer textiler sowie günstiger und einfacher Sensorzellen konnte keines der recherchierten Varianten gerecht werden.The requirement of flat, scalable textile as well as cheaper and simpler sensor cells could do justice to none of the researched variants.

Von der Firma Rayonex Biomedical GmbH wird das 'Rayshield Abschirmvlies NCV95' angeboten. Bei diesem Produkt handelt es sich um ein karbonbeschichtetes Polyestervlies, das zur Abschirmung niederfrequenter elektrischer Felder beispielsweise in einer Bettunterlage geeignet ist. Eine Verwendung desselben als piezoresistives Material in einem textilen Drucksensor ist allerdings nicht beschrieben. Der Unterschied des vorgelegten Erfindungsgegenstands zum Stand der Technik besteht darin, dass die piezoresistive, textile Schicht aus einem karbonbeschichteten Polyestervlies ausgebildet ist.Rayonex Biomedical GmbH offers the 'Rayshield shielding fleece NCV95'. This product is a carbon-coated polyester fleece, which is suitable for shielding low-frequency electric fields, for example in a bed base. However, a use thereof as a piezoresistive material in a textile pressure sensor is not described. The difference of the submitted subject of the invention to the prior art is that the piezoresistive, textile layer is formed of a carbon-coated polyester nonwoven.
Technische AufgabeTechnical task
Die Aufgabe der vorliegenden Erfindung besteht darin, einen verbesserten textilen Drucksensor bereitzustellen.The object of the present invention is to provide an improved textile pressure sensor.
Zwar ist auf dem Markt ein karbonbeschichtetes Polyestervlies (Rayshield Abschirmvlies NCV95) verfügbar und damit vorbekannt, allerdings ergibt sich aus dem Stand der Technik für einen Fachmann keinerlei konkrete Veranlassung, dieses als piezoresistive, textile Schicht in den textilen Drucksensoren des Standes der Technik einzusetzen.Although a carbon-coated polyester fleece (Rayshield shielding fleece NCV95) is available on the market and is thus already known, there is no concrete reason for a person skilled in the art to use this as piezoresistive, textile layer in the textile pressure sensors of the prior art.
Im einem konkreten Anwendungsfall sollen pflegebedürftige Personen im Bett erkannt werden sowie individuell Rückschlüsse auf Bewegungen und Lage gezogen werden können.In a specific case of application, people in need of care should be recognized in bed and individual conclusions about movements and situation can be drawn.
Technische LösungTechnical solution
Um den Anforderungen einfach zu verarbeitender, flächiger, skalierbarer textiler low-cost Sensorzellen gerecht zu werden, wird ein karbonbeschichtetes textiles Polyestervlies verwendet. Dabei wird der piezoresistive Effekt genutzt.In order to meet the requirements of easy-to-process, flat, scalable textile low-cost sensor cells, a carbon-coated textile polyester fleece is used. The piezoresistive effect is used.
Die Erfindung bezieht sich auf eine bestimmte Art, die Druckmatte auszugestalten. Es gibt neben dem karbonisierten Polyestervlies diverse andere Materialien, die zur Druckmessung in die Matte eingearbeitet werden können (z. B. eine textile, leitfähige Schicht (
Mögliche Ausfertigungen der Matte haben verschiedene Vorteile. So ist es beispielsweise bei Vliesen aber auch bei Geweben oder Gewirken von Vorteil, dass die notwendige Atmungsaktivität der Matte gegeben ist. Auch sind bei der erfindungsgemäßen Lösung eine gute Hysterese-Eigenschaft, ein günstiger Preis und gute Eigenschaften bei erhöhter Feuchte als vorteilhaft zu sehen.Possible finishes of the mat have several advantages. So it is for example in nonwovens but also in fabrics or knitted fabrics of advantage that the necessary breathability of the mat is given. Also, in the solution according to the invention a good hysteresis property, a favorable price and good properties at elevated humidity are to be seen as advantageous.
Die Erfindung beschreibt eine Sensormatte mit eingearbeiteten Drucksensoren. Der Kern der Matte besteht dabei aus einem karbonisierten Polyestervlies, das zu niedrigen Preisen erhältlich und beliebig skalierbar ist. Die Druckmessung funktioniert über das Ausnutzen des piezoelektrischen Effekts. Eingebettet wird der Kern zwischen zwei leitfähige Matten, beispielsweise metallisiertes Polyester. Durch das Ausüben von Druck wird der Kern der Matte gestaucht, so dass sich der elektrische Widerstand des Polyestervlieses zwischen den beiden metallischen Flächen verändert. Der ausgeübte Druck wird somit als Änderung des elektrischen Widerstands detektiert.The invention describes a sensor mat with incorporated pressure sensors. The core of the mat consists of a carbonized polyester fleece, which is available at low prices and scalable. The pressure measurement works by exploiting the piezoelectric effect. The core is embedded between two conductive mats, such as metallized polyester. By applying pressure, the core of the mat is compressed so that the electrical resistance of the polyester fleece changes between the two metallic surfaces. The pressure exerted is thus detected as a change in electrical resistance.
Einsatz könnten solche Drucksensoren beispielsweise im Gebiet der Personenpflege finden, damit Personen im Bett, ihre Bewegungen sowie ihre Lage erfassbar sind.Such pressure sensors could be used, for example, in the field of personal care so that persons in bed, their movements and their position can be detected.
Die Erfindung eignet sich zum Einsatz in Form von flächigen Matten zur Messung der Verteilung des Drucks auf die Matte. Ein Einsatz ist beispielsweise in Altersheimen bei bettlägerigen Patienten denkbar. Durch die Messung der Verteilung des Drucks kann ein Wundliegen (Dekubitus) frühzeitig erkannt werden, so dass notwendige Gegenmaßnahmen eingeleitet werden können. Im Jahr 2002 gab es nach Schätzung des Robert-Koch-Instituts alleine in Deutschland etwa 400.000 Personen, die in unterschiedlich schweren Ausprägungen unter den Folgen eines Dekubitus leiden.The invention is suitable for use in the form of flat mats for measuring the distribution of pressure on the mat. A use is conceivable, for example, in nursing homes in bedridden patients. By measuring the distribution of pressure, bedsores (decubitus ulcers) can be detected early, so that necessary countermeasures can be initiated. In 2002, according to estimates by the Robert Koch Institute alone in Germany, there were about 400,000 persons suffering from the effects of decubitus in varying degrees of severity.
Die Erfindung wurde bereits getestet und mit verschiedenen alternativen Materialien verglichen. Dabei stellte sich die Erfindung als geeignet heraus, um den Anforderungen eines Einsatzes beispielsweise in Altenheimen gerecht zu werden.The invention has already been tested and compared with various alternative materials. In this case, the invention turned out to be suitable to meet the requirements of an application, for example in retirement homes.
Die metallisierten textilen Polyesterflächen ((
Die Elektroden werden mit entsprechender Auswertelektronik verbunden, die den Widerstandsabfall bei Belastung erfasst.The electrodes are connected to appropriate evaluation electronics, which detects the resistance drop under load.
Die in der technischen Lösung beschriebene Funktion findet in einer mehrzonigen sogenannten Sensormatte Anwendung. Es ist nun möglich geworden, zwischen Lattenrost und Matratze flexibel und kostengünstig den Auflagendruck auf einem Bett zu ermitteln. Das einfach zu verarbeitende und handzuhabende Material ermöglicht eine individuelle Anpassung der Sensorzonen.The function described in the technical solution is used in a multi-zone sensor mat. It has now become possible, flexible and cost-effective to determine the support pressure on a bed between slatted frame and mattress. The easy-to-use and easy-to-handle material allows individual adjustment of the sensor zones.
Aus den resultierenden Widerstandsunterschieden der Sensorzonen wird ein Druckmuster erstellt, aus dem ermittelt werden kann, ob eine Person im Bett liegt, sitzt oder sich nicht im Bett befindet. Außerdem kann auf diese Art das Problem des Wundliegens, dem sogenannten Dekubitus durch Erkennung von Belastungswechseln entgegengetreten werden. Diese Erkennung kommt Menschen mit körperlichen oder geistigen Beschwerden zugute, denn durch diese Unterscheidbarkeit in der Bettbelegung können Pflegepersonal sowie Betreuende zeitnah sowohl auf eingetretene als auch antizipierte Notfälle reagieren.From the resulting resistance differences of the sensor zones, a print pattern is created, from which it can be determined whether a person is lying in bed, sitting or not in bed. In addition, in this way the problem of bedsores, the so-called pressure ulcers can be counteracted by detection of load changes. This recognition benefits people with physical or mental discomfort, as this distinctiveness in bed occupancy allows caregivers and caregivers to respond promptly to both emergencies and anticipated emergencies.
Das Anwendungsgebiet genannter flächiger textiler Sensoren erstreckt sich jedoch nicht nur auf die Anwendung zur Erfassung von Druckmustern hilfebedürftiger Personen. Denkbar sind viele Anwendungen im täglichen Leben, in der Industrie, Robotik, Arbeitssicherheit, im Automobilbereich und auch in der Sport- oder Spielzeugbranche.However, the field of application of said planar textile sensors does not only extend to the application for detecting printing patterns of persons in need of assistance. Many applications are conceivable in everyday life, in industry, robotics, occupational safety, in the automotive sector and also in the sports or toy industry.
BeispieleExamples
Im Folgenden werden die Untersuchungen verschiedener Materialien für druckempfindliche textile Sensormatten verglichen.In the following, the investigations of various materials for pressure-sensitive textile sensor mats are compared.
Es wurden Materialien untersucht, die sich zum Aufbau von flexibel anpassbaren mehrzonigen Sensormatten als Datenquelle für elektronische Datenerfassungsgeräte eignen. Entscheidender Faktor ist dabei das widerstandändernde Sensormaterial, welches seine elektrische Eigenschaft unter Einfluss von großflächigem Druck reproduzierbar ändern muss. Nach Recherchen unterschiedlichster Hersteller leitfähiger textiler Materialien mit piezoresistiven Eigenschaften wie einfachen karbonisierten ESD-Steckschäumen und Verpackungsmaterial von 3M, Quantum Tunneling Composites von Peratech oder FlexiForce Sensoren von Tekscan konnten drei Sensorvarianten als Favoriten umfangreicheren Tests unterzogen werden.Materials were investigated that could be used to build flexible, multi-zone sensor mats as a data source for electronic data capture devices. The deciding factor here is the resistance-changing sensor material, which must reproducibly change its electrical property under the influence of large-area pressure. After researching various Manufacturers of conductive textile materials with piezoresistive properties such as simple carbonized ESD foam and packaging material from 3M, Quantate Tunneling Composites from Peratech or FlexiForce sensors from Tekscan were able to submit three sensor variants as favorites for more extensive tests.
Es wurden nachfolgend pro Materialvariante 6 Durchläufe ausgeführt, mit einer Anstiegszeit von je 20 Sekunden, bei Erreichen einer Druckkraft von 1000 N eine Haltephase von je 10 Sekunden, und einer anschließenden Entlastungsphase von je 30 Sekunden. Die auf die Testfläche wirkende Kraft wird gegen den gleichzeitig gemessenen ohmschen Widerstand des Sensormaterials aufgetragen. Die Materialprüfungen beginnen belastungsfrei, und kehren jeweils nach Erreichen der Maximalkraft in einen belastungsfreien Zustand zurück.Subsequently, 6 runs were carried out per material variant, with a rise time of 20 seconds each, with a pressure force of 1000 N a holding phase of 10 seconds each, and a subsequent relief phase of 30 seconds each. The force acting on the test surface is applied against the simultaneously measured ohmic resistance of the sensor material. The material tests begin stress-free, and return after reaching the maximum force in a load-free state.
Industrielle AnwendbarkeitIndustrial applicability
Wegen der Vorteile des in der vorliegenden Erfindung eingesetzten Vliesstoffes zur Anwendung in textilen Sensormatten sind vielerlei Verwendungsszenarien denkbar. Zur ein- oder mehrzonigen Belastungsauswertung in Betten, Stühlen, Schuhen, Fußböden, als Bedienelement, im Spielzeugbereich oder in der Industrie beispielsweise als Roboterhaut. Zur Sicherstellung der Flexibilität wird als Elektrodenmaterial zur Kontaktierung ebenfalls auf Ober- und Unterseite ein Textil verwendet. Metallisiertes leitfähiges Vlies oder Gewebe eigenen sich dafür. Somit können durch einfach skalierbare textile Sensorzonen Auflagendrücke großflächig und in einem weiten Druckintensitätsbereich erfasst werden.Because of the advantages of the nonwoven fabric used in the present invention for use in textile sensor mats many usage scenarios are conceivable. For single or multi-zone load evaluation in beds, chairs, shoes, floors, as a control element, in the toy sector or in industry, for example as a robotic skin. To ensure flexibility is used as an electrode material for contacting also on the top and bottom of a textile. Metallized conductive fleece or fabric are suitable for this. Thus, easily scalable textile sensor zones can be used to record support pressures over a large area and over a wide range of pressure intensities.
