Abstract
Description
- The present invention relates to a fabric destined to be used in a fabric sensor, that can be made in a single process and obtained as a single product.
- The state of the art comprises many fabric products comprising a top layer and a lower layer, and an intermediate nonconductive layer therebetween, such that when pressing the layers towards each other, its electrical properties change at the pressure points, and a sensor is obtained.
- Such structure is found, for example in
EP1756538 , which discloses a textile pressure sensor with a flexible design which can be adapted to different shapes of load and comprising a sandwich construction with electrodes at each side of a central compressible layer. The compressible layer has a reversible effect and is applied onto a flexible base electrode layer and is covered by an insulating layer. The sensor is completed by a pattern of flexible electrodes of selected shapes applied to the insulating layer and with each electrode with a separate connection to a processor. - As another example,
GB2443208 CA2665555 discloses a capacitance pressure mapping system which includes a plurality of sensor cells created by the intersection of electrode columns and rows, and a solid elastomer dielectric separating the electrode columns and rows. - All those sensing fabrics have the drawback of having a complex configuration and complex manufacturing process, that is, are multiple processes.
- On the other hand, there are many heating fabrics belonging to the state of the art, and that are related to some embodiments of the present invention.
-
US7712826 ,EP2204482 ,W02011117413 andEP2108724 disclose a heating fabrics, some of them specially designed for vehicle seats. - However, none of the preceding documents discloses fabric sensors provided with heating function, and that can be obtained in a single process.
- To overcome the above-mentioned drawbacks, the present invention proposes a fabric product comprising a top layer and a lower layer, the top layer comprising a series of alternate insulating strips and conductive strips, the bottom layer having low conductivity properties, characterised in that it comprises cross-yarns of low conductivity material extending from the bottom layer to the conductive strips of the top layer.
- This fabric can be made in a warp knitting machine, i.e., in a single process, and provides for the basic part of a sensing fabric, when a third conductive layer equal to top layer is added at the bottom of the lower layer. This conductive surface could be the fabric itself, as shown below and claimed in claim 12.
- Preferably, the fabric product comprises an intermediate layer having low conductivity or insulating properties knitted with the top layer and the lower layer, the cross yarns extending through said intermediate layer. In this case, the fabric can be a spacer warp knitting machine too.
- This intermediate layer ensures a positive relation between pressure and conductivity, such that the sensor made with the fabric is able to measure electrical response in a direct relation with the applied pressure with high dimensional stability.
- The inventive fabric can have the following optional features, taken alone or in combination:
- the top layer comprises a series of alternate insulating strips, conductive strips and heating strips, the insulating strips being inserted between the conductive strips and the heating strip, thus providing for a multi-functional fabric. Its capabilities can be further enhanced by relating, by means of a control system, both functions, for example for heating conditioned to pressure.
- the heating strips are made of polyester and acerinox, or copper-plated or copper-silver or carbon, or any polymeric, ceramic or metallic conductive material yarns).
- the insulating strips are made of polymeric yarns.
- the conductive strips are made of copper-plated or copper-silver, or any polymeric, ceramic or metallic conductive material.
- the cross-yarns have a nylon core coated with carbon particles or any yarn with piezoresistive properties.
- all the layers are preferably made of multi-filaments yarns.
- the intermediate layer of the spacer fabric is preferably made of monofilament yarns.
- A second object of the invention is a sensing fabric comprising two inventive fabrics as set above, wherein the two fabrics are placed with the lower layers of both fabrics in contact, the strips of the two fabrics being non-parallel, and preferably perpendicularly arranged.
- Another object of the invention is a seat, mattress or floor provided with the latter sensing fabric.

By establishing a voltage between the conductive surface and the conductive strips and pressing the fabric, the fabric becomes conductive at the pressure points, thus allowing it to be used as a switch or a pressure sensor.
- Specifically, the fabric is structured in different layers, each layer with its material and knitting properties to make the fabric change its electrical properties when pressure applied to it. The top and the bottom layer are conductive and act as electrodes. Between these both conductive layers a certain configuration of yarns with insulating and specific conductivity properties are knitted. When the fabric is not pressed, there is no physical contact between the conductive yarns and the yarns of specific conductivity properties, so that conductivity between both electrodes is zero. When the fabric is pressed, physical contacts between the conductive and these yarns with specific conductivity start to happen and conductivity paths are created. The more pressure applied, the more physical contacts between these yarns, and the higher is the conductivity (lower the resistance).

Fig. 2 , the inventive fabric comprises atop layer 2 provided with a series ofalternate insulating strips 4,conductive strips 5 andheating strips 8, theinsulating strips 4 being inserted between theconductive strips 5 and theheating strips 8. - The heating function is ensured because conductive yarns increase their temperature when current circulates along them. Specific heating strips with certain conductive yarns are knitted to obtain this function separately from the pressure sensor function. Between both functions - that means, between both strips- insulating strips are knitted to avoid any current circulating between the heating and the sensing yarns.

fabrics 1 according to any of the inventive embodiments previously described, wherein the two fabrics are placed with the lower layers of both fabrics in contact, the strips of the two fabrics being non-parallel, and preferably perpendicularly arranged, i.e., in an analogous manner as disclosed inCA2665555 . - The sensing fabric can be applied to seats, for example a vehicle seat, a theatre or stadium seat.
