In one embodiment of the sensor device according to the invention, the functional layer is located between the carrier layer and the protective layer, and the functional layer has a planar radiation sensor array, which is at least embodied: for detecting and measuring integral, electromagnetic and / or optical properties such as color, reflectivity, IR spectrum, UV spectrum or the like and for detecting and reading special, structured, applied electromagnetic and / or special optical information such as data carriers with an electromagnetically or opto-electronically readable code in or on one or more outer surfaces, below or in the vicinity of Capture page placed object.

• A plurality of electromagnetically sensitive or electromagnetically sensitive components at least for receiving electromagnetic signals of one or more RF antennas (eg resonant antenna or RFID tag) or light reflections from the object itself or from the code on the object
• A planar light-emitting array arranged at least for illuminating the object and in the special case of the code with a plurality of light-emitting components, so that with the radiation sensor array sensor data of at least one arranged opposite the detection side object can be detected, the a property and / or a state and or represent the distance of the object from the radiation sensor array and / or information of a data carrier on the object.

The object may be z. B. be a container in which goods are stored and / or transported. Also, the object may be a plurality of object parts. For example, the plurality of object parts can form a bulk material. Also, an object part of a single items such. B. an industrial storage product, such as a z. B. spare part and dabie z. B. be an electronic device or a guide plate. The object part can also be a commodity such. B. be a container or a bottle.

Alternatively or additionally, in the functional layer also at least one active or be integrated passive antenna or more active or passive antennas, which serve at least for irradiating or reading an equipped with passive resonant antennas or active transmitting antenna object against the detection side, which emit due to activation by the detection layer, the Objektpraesenz and / or a special object code. By means of such a functional layer, it is possible to detect intensity of an RF signal received from an object arranged on the detection layer, the distance, the position and a code of objects arranged on the detection layer and to be evaluated by a downstream electronics.

The detection side of the sensor device may be formed as a footprint on which an object can be placed with the outer surface, which also forms the support surface or bottom surface of the object. However, the detection side can also be realized such that the sensor device can be arranged or mounted in a side wall section or a top surface of a frame device such as a shelf or a room such as a storage room. When an object is arranged on the sensor device, the outer surface of the object facing the sensor device, or which can be brought into contact with a surface of the sensor device without the weight force of the object acting on the detection side, can be used to detect characteristics or states of the sensor Object such as its position with respect to the sensor device or a coordinate system thereof and distance from the sensor device are detected.

In this case, "arranging on" is understood as an approximation of an infinite range and in particular of a predetermined maximum detection distance to the immediate contact, but also an approximation of an object to a distance to the sensor device that is smaller than the lateral dimensions of the detection side or outer surface of the object is. With regard to the detection of an object by means of an electromagnetic-sensitive component, the detection range of the sensor device may be rectangular or square-shaped. In general, "contacting" or "bringing in a detection area" means approximating an object to a distance that is smaller than the detection area and, in the example of a rectangular or square implementation thereof, as the smallest edge length of the object rectangular or square detection side or outer surface is.

In this case, the surface of the detection side may be larger than an outer surface of the object. This allows objects with differently sized and differently shaped outer surfaces to be brought into contact with the detection side or to simultaneously detect several objects. But it can also be the detection side is smaller than the outer surface of the object, d. H. the detection side of the sensor device is a partial area of an entire detection side.

The carrier layer is flat, d. H. it typically has a thickness which is smaller than the lateral dimensions of the carrier layer in length and width, when e.g. B. is a rectangular support layer. If the carrier layer z. B. is formed circular or elliptical, the diameter or the diameter is greater than the thickness of the carrier layer, with the disposed between the carrier layer and the detection side radiation sensor array can be electromagnetically and especially optically readable information and / or codes, such z. B. RFID tags and one or two-dimensional barcodes are read. Such codes may contain information about the content of the object, its origin, or its destination. For this purpose, the sensor device has a plurality of electromagnetically sensitive components which form the radiation sensor array in a side-by-side arrangement. Each electromagnetically sensitive component detects light reflections of only a portion of the code. The radiation sensor array thus allows the immediate detection of the code in a surface portion of an outer surface of an object, without requiring a relative movement between the detection side and the outer surface with the code. On the one hand, this speeds up the read-out process. On the other hand, the evaluation of such a radiation sensor array is simplified, since no such relative movements are required for sensor signal generation when the detection side is larger than the outer surface of the object. Thus, in this case, an evaluation and control device, which is connected to the radiation sensor array, does not have to process or filter out such relative movements in the sensor signal evaluation and can therefore be made simpler.

According to the invention, an emission array with a plurality of electrical functional components is provided in the functional layer, which are designed as electromagnetic radiation emitting and especially light-emitting functional components to irradiate an object surface and in particular a code formed or displayed on the object surface such that the emitted rays can be reflected from the surface and detected with the electromagnetic radiation emitting radiation sensor array. Upon irradiation of a code arranged on a surface, it can therefore also be read out, in particular, if an irradiation and / or illumination of the code on a detection side of the sensor device takes place as a footprint and the outer surface of the object is designed as a bottom surface. The emitting components are components of the sensor device and are themselves stationary in a preferred embodiment of the application of the sensor device. In a preferred embodiment, in which no electronics or optics for radiation deflection is provided, the exit direction of the radiation emitted by the emitting components is unchangeable, so that each of the emitting components irradiates only a portion of the object surface or of the code.

According to one embodiment of the invention, the combination of emission array and radiation sensor array is designed so that the position of one or more objects arranged opposite the detection layer relative to the detection layer with sufficient accuracy both static (time-independent) and dynamic (as a function of time) in the three -dimensional space at specific times or can be recorded continuously. In this case, a synchronized, pulse-like emitted activation of the integrated in the functional layer emission array in combination with location and time-resolved readout of the also arranged in the functional layer radiation sensor array. In this case, the radiation emitted by partial areas or by the entire radiation sensor array is reflected by the objects located in front of the detection layer. As a result of the different distance of the respectively reflecting object surface subregions from the radiation sensor array, detectable propagation time differences of the radiation components absorbed and / or reflected in the individual sensors of the radiation sensor array occur. The radiation sensor array signals that are temporally and spatially resolved in this way are subsequently digitized by downstream electronics and a correspondingly executed software program subsequently permits the evaluation and visual representation of the position, direction of movement, relative speed and curve shape of one or more objects located in front of the detection layer.

In a special arrangement, this special case can also be used to detect the level of a container or a shelf. Here, the invention is installed so that the detection layer is spatially arranged above the objects and detects the objects from above. In this case, the combination of emission array and radiation sensor array is used to produce a spatially resolved surface profile of the objects located below the detection layer in the container or on the shelf. In this case, according to the method described above, the distances of the individual surface elements facing the acquisition layer are detected and then combined by means of suitable software to form an overall surface profile. In the highest resolution case, one partial element of the total surface profile corresponds to one sensor element of the radiation sensor array in the detection layer. By individual subtraction of the spatial distance of the individual sub-elements of the total surface profile thus detected from the spatial distance of the respective equivalent sub-elements of the total surface profile of the empty container or the empty shelf can in combination with appropriate scaling of length and width of the area covered by the surface profile surface by means of suitable software the net volume occupied by the objects is determined. This can be used in conjunction with a defined maximum fill level (equivalent to a minimum distance of the total surface profile from the acquisition layer) for determining and displaying the fill level of a container or shelf.

By emitting and electromagnetically sensitive components are meant components that can emit or detect both electromagnetic radiation in the visible wavelength range, in the IR and / or UV range and in the RF range. Furthermore, the various emitting and electromagnetically sensitive components can be designed and matched to one another such that they can selectively emit or detect respectively only radiation in the visible, in the IR or UV range, or in the RF range. In this respect, this arrangement also allows the spectroscopic analysis of the correspondingly positioned object.

The emitting and electromagnetically sensitive components are manufactured by means of additive techniques, d. H. they consist of materials that z. B. layered one above the other, and are applied to a lying under the emitting and electromagnetically sensitive components layer. During fabrication, there was no conversion or change in physical or chemical properties of the material of the underlying layer.

Thus, the sensor device surprisingly allows rapid and reliable detection of an electromagnetically readable code mounted in an object, or more specifically an optoelectrically readable code attached to an exterior surface of an object such that information about shape, location, motion vector, motion velocity, reflectance and absorption characteristics including color and the content of the object, its origin, or its destination, but also about its state (empty, full) or properties for z. B. a powerful Storage system are available. In this case, the sensor device has a simple structure without moving parts for radiation deflection and is therefore particularly robust. It is suitable for. For use in an environment where strong machine induced vibration would degrade or destroy moving parts of a radiation deflecting system.

In addition, this sensor device can be integrated in particular in so-called E-pads, i-pads and similar, interactive flat-screen touch screens to one or more objects placed on such a pad in terms of optical, in connection with suitable software applications installed there (so-called apps) Characteristics, size, motion and optically or electromagnetically readable codes to capture, recognize and characterize with respect to other, retrievable in databases properties or identify. This generally includes the electromagnetic and especially optical analysis of solid, liquid or gaseous substances or living organisms and, in particular, also applies to the presence, the spatial distance or relative movements of one or more fingers of the human hand relative to the E-pad. The latter can be used in particular for non-tactile, analogue guided, interactive, control and monitoring processes by means of suitable apps for various control and regulatory processes where software on the pad directly or indirectly via other software and / or facilities (via cable, WiFi, Bluetooth, GSM etc.).

It is preferably provided that the first functional layer has first partial regions, in which at least one electromagnetically sensitive or optically sensitive element is arranged, and the first functional layer has second partial regions, in each of which an electromagnetically emitting or in the optical region light-emitting Component is arranged. Thus, the electromagnetically sensitive and the emitting components are arranged in a plane side by side, which are limited to the sensor device upper side from the detection side and the sensor bottom side of the support layer. The electromagnetically sensitive and the emitting components are thus applied to the same layer, such as in an electrode layer serving as a ground terminal. The advantage here is that both the electromagnetically sensitive and the emitting components via the same electrode layer can be electrically connected, for. B. with a ground potential. The functional layer may also have two sub-layers, wherein in a first of the two sub-layers z. B. the electromagnetically electromagnetically sensitive components and in the second sub-layer, the electromagnetically emitting components are arranged.

Furthermore, it is preferable for at least one second subregion to be arranged in the functional layer between two first subregions. Thus, the emitting and electromagnetically sensitive components are alternately in the form of a matrix or a grid -. B. in rows and columns - arranged. By this arrangement, a uniform and therefore optimal lighting z. B. the code located on an object by the emitting components and at the same time a reliable detection of the code achieved by the sensitive components.

In general, the functional elements can be realized as material dots on a layered matrix material, which can be applied in particular to the matrix material in a printing process. The layered matrix material may in particular comprise a polymer or consist of a polymer.

In the special case of optical applications, all suitable solid-state components, ie. H.

The electromagnetically sensitive components may passive components, such. As photodiodes, which are functional without power supply and convert the light incident on them directly into electrical energy. The advantage here is that no power supply and thus no traces for energy supply must be made so that the total manufacturing cost is reduced.

The electromagnetically sensitive components but also active components, such. B. phototransistors, whose electrical resistance varies depending on the light intensity. Phototransistors have the advantage over photodiodes that they are more sensitive to light intensity changes and at the same time amplify the sensor signal. However, the response time of phototransistors is greater than changes in photodiodes, ie slower. It is also possible to use a photoresistor which changes its resistance as a function of the light intensity. It is preferably provided that the plurality of electromagnetically sensitive components is formed by organic photosensors (OPS). Such organic photosensors may consist of several, additive applied, z. B. from printed layers of different materials exist, and be designed as a photodiode, phototransistor or photoresistor. The materials to be printed may contain polymers in liquid or pasty form, which may be electrically conductive, semiconducting and insulating. As printing techniques z. As the screen printing technique, the inkjet technique or mass printing techniques such as gravure, offset or flexo printing use. In particular, but not exclusively, allow mass printing techniques such. As the gravure printing, flexible materials such as films to print, so that the carrier layer itself can be flexible. A film is understood to mean a flat material section which is limp, ie it deforms under the influence of its own weight force. Furthermore, the nanoprite lithography can be used. These printing techniques allow a structured application in which material is applied to the desired structure accordingly. So it is only applied material at the desired locations, while at the points where no material should be, no material is applied. Alternatively, in a first step, a full-surface order, z. B. be done by its coating or spraying an aerosol, wherein the material applied over the entire surface is structured in a second step by means of photolithographic techniques. Finally, a deposition can be provided from a gas phase, such as. As the organic vapor deposition (OPVD). These embodiments also apply to the more general case of electromagnetic sensors, in the simplest case receiving antennas, which can also be made by the various illustrated material and printing techniques.

In the special case of optical applications, all suitable solid-state components can be used as light-emitting components that can convert electrical energy directly into light, such. B. electroluminescent components or devices with a semiconductor junction, take place at the recombinations. It is preferably provided that the plurality of light-emitting components is formed by organic LEDs (OLEDs). Such organic LEDs may consist of several, additive, z. B. printed layers of different materials. The materials to be printed may contain polymers in liquid or pasty form, which may be electrically conductive, semiconducting and insulating. As printing techniques can also z. As the screen printing technique, the inkjet technique or mass printing techniques such as gravure, offset or flexo printing use. Again, allow in particular mass printing techniques such. B. gravure printing, flexible materials such as films to print, so that the carrier layer itself can be flexible. Furthermore, nanoprinter lithography can also be used here. These printing techniques allow a structured application in which material is applied to the desired structure accordingly. Furthermore, in a first step, a full-surface order, z. B. by coating or spraying of an aerosol, wherein the material applied over the entire surface is structured in a second step by means of photolithographic techniques. Finally, a separation from a gas phase can also be provided here, such. As the organic vapor deposition (OPVD). The OLEDs may include polymeric OLEDs that are deposited from solution, and SOMLEDs, PLEDs, or SOLEDs, in which organic layers have been evaporated from the vacuum onto an anode. These embodiments also apply to the more general case of electromagnetic transmitters, in the simplest case transmit antennas, which can also be made by the various illustrated material and printing techniques.

The carrier layer can be formed as a substrate, on which only the electromagnetically sensitive and emitting components are applied, and which otherwise has no further function. It is preferably provided that additionally one or more pressure sensors are embedded in the carrier layer. The pressure sensors allow such. Example, in a simple manner, the detection of the presence of an object by directly contacting the detection side of the sensor device with the outer surface of the object. The pressure sensors can be designed as strain gauges. Furthermore, piezoelectric or -resistive areas or elements can be introduced into the carrier layer, for. B. in the form of doped portions in a semiconductor material. Finally, a ferroelectret can be used as the carrier layer. Such a ferroelectret is an elastomer or polymer foam, such as. B. polypropylene (PP) having cavities in which particles, for. B. of calcium carbonate (CaCo3), which are electrically charged and thus polarized. The electrical conductivity of such ferroelectrics changes under pressure. This allows z. As the detection of the presence or a weight determination of an object, or a contour detection of the bottom surface of the object, when the detection side of the sensor device is designed as a footprint and the outer surface of the object as a bottom surface. Thus, on the one hand by the weight z. B. the degree of filling of the object can be determined and on the other hand by the contour detection more information can be determined. Thus, on the one hand by the weight z. B. the degree of filling of the object can be determined and on the other hand by the contour detection more information can be determined. For this purpose, the sensor device z. B. have two surface portions, namely a first with the radiation sensor array and the light emitting array, and a second one with the pressure sensors. For example, the second portion of the first portion may circulate in a frame shape, wherein the first portion is embedded in a recess, so that a weight load of the first portion is transferred to the second portion. So z. For example, the outer contour of an outer surface of an object may be detected by the pressure sensors in the frame-shaped second section while the code is detected by the radiation sensor array in the first section in the center.

Finally, provision is preferably made for the carrier layer to be flexibly deformable by deformation of the detection side. In order for the carrier layer to be deformable by the weight force of an object, at least the functional layer arranged between the detection side now formed as a footprint and the outer surface of the object correspondingly designed as a bottom surface is likewise designed to be flexibly deformable.

Furthermore, the invention relates to a sensor system, comprising at least one such sensor device, as well as with an evaluation and control device, which is designed at least for reading the radiation sensor array and for driving the emission array.

The evaluation and control device controls the detection process of an optically readable code z. B. as follows: To read the code, the light-emitting components of the light-emitting array are supplied with electrical energy, for example from a battery. Thus, the light array illuminates the code. The light reflected from the code is detected by the radiation sensor array. It is then read by the evaluation and control device, which provide the electromagnetic sensitive components which sensor signal. Thus, the code can be evaluated with the evaluation and control device.

On the carrier layer 4 can completely cover the insulation layer 26 be upset. It serves for electrical insulation of the subsequent layers of the carrier layer 4 if the backing layer 4 consists of an electrically conductive material. If, however, the carrier layer 4 is made of an electrically insulating material, can on the insulation layer 26 be waived.

The optional on the insulation layer 26 applied contact layer 28 consists of an electrically conductive material or is formed or composed of an electrically conductive material. In the electrically conductive material, it may, for. Example, be a metal such as aluminum, or an electrically conductive plastic or adhesive. The contact layer 28 forms a ground connection for the at least one functional layer 10 and Z. B. for the radiation sensor array 8th and the light-emitting array 14 ,

When forming a radiation sensor array 8th in the functional layer 10 this has a plurality of electromagnetically sensitive components 12 on, which is electrically connected to the contact layer 28 are connected. When forming a light-emitting array 14 in the functional layer 10 this has a plurality of light-emitting components 16 on, which also electrically with the contact layer 28 are connected.

In this example, the light-sensitive devices 12 the first subareas 10a the functional layer 10 arranged while the light-emitting devices 16 in the second areas 10b the functional layer 10 are arranged. Thus, the electromagnetically sensitive components form 12 and the light emitting devices 16 a matrix or grid-shaped arrangement with rows and columns, in which an electromagnetically sensitive device 12 of light emitting devices 16 is adjacent and vice versa (see 2 ). This arrangement provides optimum illumination for detecting optoelectronic codes with the electromagnetically sensitive components 12 reached.

In the electromagnetically sensitive components 12 These are, in particular, organic photosensors (OPS) which, in the present embodiment, are in the form of organic photodiodes (OPS), which, for. B. on the contact layer 28 are printed. Instead of photodiodes but also other electromagnetically sensitive components or optoelectric sensor elements can be used, such.

In the light emitting devices 16 it can be organic LEDs (OLEDs), the z. B. also on the contact layer 28 are printed. Instead of organic LEDs (OLEDs), electroluminescent components can be used.

The on the functional layer 10 applied masking layer 29 has a plurality of contact openings 31 on, with the electrical contacting of the electromagnetically sensitive components 12 and the light emitting devices 16 becomes possible. For this is on the masking layer 30 made of electrically non-conductive material, a conductor layer layer 31 made of an electrically conductive material, for example, again a metal, such as aluminum, or of an electrically conductive plastic or adhesive. The masking layer 29 is made of a material which is pervious to such wavelengths as that of the light emitting devices 16 emitted and from the electromagnetically sensitive components 12 be received. In contrast to the masking layer 30 obstructs the conductor layer or burying layer 31 due to their small areal extent in the form of strip conductors 15 respectively. 44 the passage of light only insignificantly.

Around the conductor track layer 31 but also the underlying layers, to protect against mechanical or chemical damage, is on the conductor track layer 31 the transparent protective layer 32 applied. The transparent protective layer 32 is special for such wavelengths permeable to those of the electromagnetically sensitive components 12 received and from the light emitting devices 16 be emitted. Thus, the detection accuracy can be increased, as this interference is filtered out by light signals of different wavelengths.

The transparent protective layer 32 forms the sensor device top of the sensor device 2 and has the capture page 6 which can be brought into contact with an outer surface of an object described below.

The embodiment of the sensor device 2 according to the 7 differs from the embodiment of the sensor device 2 according to the 1 in that for the functional layer or carrier layer 10d In the present embodiment, a ferroelectret is used. Such a ferroelectret is an elastomer or polymer foam, such as. B. polypropylene (PP) having cavities in which particles, for. B. of calcium carbonate (CaCo3), which are electrically charged and thus polarized. The electrical conductivity of such a ferroelectric changes when pressure is applied. Will this functional layer or carrier layer 10d Pressed together, the electrical conductivity of the carrier layer changes in sections 4 , Thus, the functional layer or carrier layer 10d according to the 7 a plurality of pressure sensors 18 on.

Furthermore, in the embodiment of the 7 all other layers similar to the functional layer or carrier layer 10d elastically deformable, ie the insulation layer 26 , the contact layer 28 , the masking layer 29 , the conductor track layer 31 and the transparent protective layer 32 , This allows a deformation on the footprint 6 the sensor device 2 from the transparent layer 32 over the other layers, namely the insulation layer 26 , the contact layer 28 , the masking layer 29 and the conductor layer 31 in the functional layer or carrier layer 10d can be transferred and there is a deformation of the functional layer or carrier layer 10d causes. This deformation causes a change in the electrical conductivity of the functional layer or carrier layer 10d and thus can be detected.

Because such pressure sensors 18 are also sensitive to light or heat, the insulating layer is optically opaque, to prevent light to the pressure sensors 18 reach and there causes a Messwertverfälschung.

It will be up now 8th Reference is made to a sensor system 1 with a sensor device 2 according to the 1 . 5 or 7 shows.

In the embodiment according to the 8th are like in the embodiments of 1 . 5 and 7 the light emitting devices 16 as organic LEDs (OLEDs) formed while the electromagnetically sensitive components 12 are designed as organic photodiodes that are able to convert light directly into electrical energy. The electromagnetically sensitive components designed as photodiodes 12 do not need power supply lines. About the tracks 44 the conductor track layer 31 are the electromagnetically sensitive components 12 of the 8th with an evaluation and control device 60 of the sensor system 1 electrically connected, with which an evaluation is possible, which of the individual electromagnetically sensitive components 12 are exposed to light and which are not. To supply the evaluation and control device 60 and the light emitting devices 16 has the sensor system 1 also a battery 62 as an energy source or storage on. In this case, the sensor system 1 of the 8th be formed such that electrical energy with the formed as photodiodes electromagnetically sensitive components 12 , is recovered, to charge the battery 62 can be used. This is a particularly energy-saving operation of the sensor device 2 or the sensor system 1 possible. The power supply lines 63 can over the interface 37a or a separate interface 39 be guided in the respective functional layer or be connected to this.

9 shows an object 20 formed in the present embodiment as a container having five outer walls defining an interior of the container, of which an outer surface 24 is formed in the present embodiment as a bottom surface. On this outer surface 24 is a data carrier in the form of an opto-electronically readable code 22 applied, which is a two-dimensional barcode ("2D barcode"). The code 22 can be in coded form z. B. Information about the content of the object 20 , its origin or a destination included.

10 shows a schematic representation of the reading of a code 22 using a sensor device 2 according to an embodiment according to 1 or 5 , The object 20 is with its designed as a bottom surface outer surface 24 on the capture page 6 the sensor device 2 arranged, which is formed in the present embodiment as a footprint. That is, the object 20 with its bottom surface by its weight on the footprint of the sensor device 2 pressed. Deviating from this, the sensor device 2 also used to codes 22 read on a trained as a side surface outer surface of the object 20 are arranged. In this case, the sensor device 2 no acquisition page selected as footprint 6 but a lateral acquisition page 6 on.

In the in 10 shown position is selected as the bottom surface outer surface 24 of the object 20 in direct contact with the registration page 6 the sensor device 2 , However, a readout of the code 22 with the sensor device 2 even possible if a small distance between the detection side 6 and the outer surface 24 of the object 22 consists. By a small distance is meant a distance whose length is smaller than the lateral dimensions of the outer surface 24 of the object 20 or smaller than the lateral dimensions of the footprint 6 the sensor device 2 are.

For reading the code 22 become the light emitting devices 16 (please refer 1 . 2 and 3 ) of the light-emitting array 14 with electrical energy, for example from the battery 62 (please refer 8th ), provided. Thus illuminates the light-emitting array 14 the code 22 , For this purpose emits the light-emitting array 14 Light with a wavelength in the visible range. Alternatively or additionally, the light-emitting components 16 of the light-emitting array 14 be designed so that they emit light with wavelengths in the IR or UV range. The emitted light passes through the masking layer 29 , the conductor track layer 31 and the transparent protective layer 32 , The light is from the code 22 reflected, and the reflected light is after passage of the transparent layer 32 , the wiring level 31 and the masking layer 29 from the radiation sensor array 8th with the electromagnetically sensitive components 12 (please refer 2 and 3 ) detected. Due to the matrix or grid-shaped arrangement of the light-emitting components 16 of the light-emitting array 14 becomes a uniform illumination of the code 22 achieved and by the likewise matrix or grid-shaped arrangement of the electromagnetically sensitive components 12 of the radiation sensor array 8th can the code 22 with at least one resolution, which is the minimum feature size of the code 22 equivalent. It will then pass over the conductor layer 31 from the evaluation and control device 60 read. Thus, the code can 22 by means of the evaluation and control device 60 (please refer 8th ) be evaluated.

If an object 20 with its outer surface 24 on the footprint 6 the sensor device 2 is placed, are the electromagnetically sensitive components 12 at least partially obscured. These electromagnetically sensitive components 12 provide significantly less electrical energy, which also with the evaluation and control device 60 can be detected. Thus, by evaluating the electromagnetically sensitive components 12 be detected, whether an object 20 on the floor 6 the sensor device 2 or not.

Furthermore, by evaluating individual electromagnetically sensitive components 12 the outer contour of the outer surface 24 of the object 20 be determined, giving more information in relation to the type of the object 20 can be determined.

The possibility of the presence of an object 20 on the footprint 6 To capture, as follows, to control the sensor system 1 ( 8th ) be used:
On detecting the presence of an object 20 on the footprint 6 be through the evaluation and control device 60 (please refer 8th ) the light array 14 and the radiation sensor array 8th activated, that is, the evaluation and control device 60 causes the light emitting devices 16 with electrical energy from the battery 62 be supplied. At the same time evaluates the evaluation and control device 60 that of the photoelectrically sensitive components 12 supplied sensor signals to the code 22 to determine. Thus, the electromagnetically sensitive components serve 12 almost as a switch to activate the sensor system.

In an analogous way, the electromagnetically sensitive components 12 also act as a switch to the sensor system 1 to disable. On a removal of an object 20 from the footprint 6 changes the of electromagnetically sensitive components 12 supplied electrical energy, what of the evaluation and control device 62 is detected. Then the evaluation and control device disconnects 62 the light-emitting components 16 electrically from the power supply device or the battery 62 , As the electromagnetically sensitive components 12 are designed as photodiodes, the evaluation and control device 62 the mode of operation of the photodiodes formed as light emitting devices 12 change. While the photodiodes for detecting the code 22 operate in quasi-short circuit or in the stopband, now the photodiodes are operated as photo elements, so that now no longer from the object 20 Covert photodiodes provide electrical energy that is in the battery 62 can be cached to the evaluation and control device 60 in a stand-by mode, in which the evaluation and control device 60 only the electromagnetically sensitive components 12 evaluated in terms of their generated electrical energy and after activation z. B. the light emitting devices 16 to supply with electrical energy.

The sensor system 1 can be a functional layer 10 with a plurality of emission components emitting electromagnetic radiation 16 for forming an emission array and a plurality of electromagnetically sensitive functional components 12 to form a sensor array. In this case, the evaluation and control device 60 a code recognition function for recognizing one by the electromagnetically-sensitive functional components 12 detected pattern on one of the acquisition-side surface 2a facing surface 22 of the object 20 exhibit.

In particular, it can be provided that the code recognition function is an approximation function 65 which is embodied such that, in a predetermined determination period, it emits, by at least one emitting functional component, the emission of a radiation pulse predetermined in terms of its time by emission components emitting at least one electromagnetic radiation 16 commanded and of at least one electromagnetic-sensitive functional component 12 in the period receives a reflective radiation pulse, in a pulse identification function compares at least one property of the emitted with the detected radiation pulse and identifies an identity of the radiation pulse at a match or at least predetermined similarity of the property of the emitted radiation pulse with a property of the detected radiation pulse.

The approach function 65 may comprise a distance-determining function which detects a time difference between the time at which the emitted radiation pulse from the evaluation and control device 60 has been emitted, and the time at which the detected radiation pulse from the evaluation and control device 60 via an input interface 63 has been received, and from the determined time difference by means of a duration of the emitted radiation, a distance of the object 20 between the object surface and the detection-side surface 2a the sensor device 2 determined. Furthermore, the code recognition function may comprise an information retrieval function which, in the case that the distance of the object 20 between the object surface and the detection-side surface 2a of the sensor device 2 falls below a predetermined code detection distance, by means of the electromagnetic-sensitive functional components 12 captured pattern derives a code information and at the output interface 64 provides. To the output interface 64 a display device can be connected, with which the code information can be displayed. Also can connect to the output interface 64 a transmission device can be connected, with which the code information can be transmitted to receiving devices.

The evaluation and control device 60 can be a flow control 69 have, with the functional modules of the evaluation and control device 60 can be controlled in their sequence.

According to one embodiment of the sensor system 1 is provided that in the functional layer 10 functional components 11 are arranged distributed over the surface, the visible light in at least one predetermined color to display display formats on the detection-side surface 2a can generate, and that in the functional layer 10 functional components 11 are arranged distributed over the surface, the pressure-sensitive to the action of an object on the detection side surface 2a or proximity-sensitive to objects that are below a maximum distance from the detection-side surfaces 2a are located. In this case, the evaluation and control device 62 have a function with which by means of the functional components 11 be activated to produce a visible light of a predetermined color such that by means of the color on the detection side surface 2a an input format or an input element, such as. B. is represented by a geometric representation element such as a circle input or actuation field for illustration and that in the thickness direction Z of the sensor device 2 seen within the input format located pressure-sensitive functional components 11 to be activated, the system having a command function that operates at a minimum actuation of the acquisition-side surface 2a generates within the display format a predetermined, the operation corresponding command signal for output to an application device or an application system.

11 shows a schematic representation of the reading of a code 22 using a sensor device 2 according to the second embodiment (see 7 ). The operation of the radiation sensor array 8th and the light-emitting array 14 corresponds to the operation of the sensor device 2 the first embodiment, with reference to 5 was explained.

The following explains the differences:
If an object 20 with its outer surface formed as a bottom surface 24 formed on the footprint detection side 6 the sensor device 2 is placed by the weight of the object 20 the protective layer 32 , the conductor track layer 31 , the masking layer 29 , the contact layer 28 and the insulation layer 26 deformed, giving the weight of the object 20 on the carrier layer 10d is transmitted. The in the carrier layer 10d integrated pressure sensors 18 then change their electrical resistance, which also with the evaluation and control device 60 can be detected. They are thus designed as weight sensors. Thus, by evaluating the pressure sensors 18 in the carrier layer 10d be detected, whether an object 20 on the floor 6 the sensor device 2 or not.

Furthermore, by evaluating individual pressure sensors 18 in the carrier layer 10d the outer contour of the outer surface formed as a bottom surface 24 of the object 20 be determined, giving more information in relation to the type of the object 20 can be determined.

Finally, by evaluating the pressure sensors 18 the weight of the object with its content 20 be determined and thus determined whether the object 20 empty or full, or its degree of filling be determined. Also, when you know the weight of the object 20 on the nature of the content of the object 20 getting closed.

The possibility of the presence of an object 20 on the footprint 6 can also be used to control the sensor system ( 8th ) be used:
On detecting the presence of an object 20 on the footprint 6 be through the evaluation and control device 60 (please refer 8th ) the light array 14 and the radiation sensor array 8th activated, that is, the evaluation and control device 60 causes the light emitting devices 16 with electrical energy from the battery 62 be supplied. At the same time evaluates the evaluation and control device 60 that of the photoelectrically sensitive components 12 supplied sensor signals to the code 22 to determine. Thus, the pressure sensors serve 18 in the carrier layer 10d almost as a switch to activate the sensor system.

In an analogous manner, the pressure sensors 18 also act as a switch to the sensor system 1 to disable. On a removal of an object 20 from the footprint 6 the electrical resistance of the pressure sensors changes again 18 , what of the evaluation and control device 26 is detected. Then the evaluation and control device disconnects 62 the light-emitting components 16 electrically from the battery 62 , Furthermore, if the electromagnetically sensitive components 12 are designed as photodiodes, the evaluation and control device 62 the mode of operation of the photodiodes formed as light emitting devices 12 change. While the photodiodes for detecting the code 22 operate in quasi-short circuit or in the stopband, now the photodiodes are operated as photo elements, so that now no longer from the object 20 Covert photodiodes provide electrical energy that is in the battery 62 can be cached to the evaluation and control device 60 in a stand-by mode, in which the evaluation and control device 60 the pressure sensors 18 evaluates and after activation z. B. the light emitting devices 16 to supply with electrical energy.

Of course, with reference to 5 described evaluation of the electromagnetically sensitive components 12 and the referring to 11 described evaluation of the pressure sensors 18 can also be combined to the evaluation accuracy and reliability of the sensor system 1 to increase.

There will now be a method of manufacturing a sensor device 2 according to the first embodiment (see 1 ) and the second embodiment (see 5 and or 7 ) explained. In the following, the layer which is provided as the first with a further layer is referred to as the substrate.

Starting from a serving as a substrate carrier layer 4 . 10d that without pressure sensors 18 or with pressure sensors 18 may be provided on the top of the carrier layer 4 . 10d an insulation layer 26 , for example, made of electrically insulating plastic applied over the entire surface. Further, the insulating layer may be optically opaque to prevent light from being applied to the pressure sensors 18 can get there and causes measured value distortions. The insulation layer 26 can z. B. in the form of a film on the carrier layer 4 is laminated, or a z. B. in liquid form present material is applied, for. B. by a printing process, after its drying out the insulation layer 26 forms.
