From the prior art are after DE 103 28 359 A1 already modular, washable electronic systems known. For example, modular microelectronics systems exist for use in wearable electronics, where the electronics are rigidly housed and the contacts to the connection module are completely covered, with a seal between the modules, resulting in a relatively large size and does not meet the requirements Demands for miniaturization and component integration The flatness of the electronic system and its flexibility required for integrating the electronics in textile / flex material can not be achieved in this way.

The DE 10 2004 024 718 A1 describes populated printed circuit boards, which are surrounded by a housing, for example, from an injection-molded thermoplastic material body. The circuit board has contact elements, which are guided to the outside. Electronic components may be enclosed by the housing so that they are moisture-proof.

The EP 1 231 824 A2 also shows electronic components, which together with a conductor foil, on which they are connected by conductor tracks, between a first housing part and a second housing part can be embedded, the latter elements are in turn embedded in a plastic sheath. In particular, an optimal seal against external influences such as water is mentioned. On the surface here windows for contacting the conductor sheets / components are arranged. The components, the conductor foils and the windows can be arranged on both sides. By means of the contact windows and further, overlapping arranged receiving parts and other, externally accessible components can be arranged.

The EP 1 646 271 A2 shows cushioned electronic components, which can also be arranged on both sides of the central board, wherein the electronic components are liquid-tightly enveloped and can be contacted by outwardly guided line connections.

The DE 198 56 839 C2 shows a central conductor element to which electronic components can be connected, which can then be arranged sealingly in a transmission control unit.

The DE 10 2005 004 443 A1 shows a system integrated in clothing for the acquisition and analysis of pulse and activity parameters of persons. Electrodes can be affixed to the inside of the clothing using "electrodes with pushbuttons", and the assembly which picks up the signals can also be mechanically fastened to the clothing by means of press studs.The pushbuttons can serve as signal conductors US Pat. No. 6,350,129 B1 refers to portable electronic devices, here by means of bands using conductive snaps individual devices can be electrically interconnected.

The DE 11 2004 002 136 T5 describes flexible switch devices that can be implemented integrated into garments. Again, push buttons can be used as electrical conductors.

The US 6,210,771 B1 describes textiles in which, for example by means of conductive fibers electrical circuits / electronic components are integrated. The DE 20 2004 019 172 U1 describes electrodes that are integrated into the clothing. The DE 10 2004 042 397 A1 describes electrically conductive fabric fibers for the formation of electrically conductive, textile contact connections. Again, electrically conductive push buttons are described. The DE 10 2004 063 061 A1 describes variously executed, bendable and / or foldable flat conductor to which electronic components can be connected. Also the US 5,895,277 A describes similar conduit elements. The DE 10 2005 003 132 A1 describes the lathering of flexible or rigid printed circuit boards.

The Disadvantages of such solutions consist mainly in that for the washing process, the connection contacts completely waterproof covered or must be closed. This requires either an additional Part for hermetic sealing the contact area or such a modular structure, the between the modules located contacts through the modules themselves and their closes intermediate seals. This is with additional expenses connected.

electronic systems with encapsulated or housed electronics and direct lead out of insulated wires or strands or flat conductors from their enclosure may indeed Demands for miniaturization and flexibility meet, but are not waterproof sealable, since the detergent between insulation and wire or Strand, in particular by capillary action, penetrate into the enclosure and damage the electronics can.

Usual electronic connectors with rugged pen or knife contacts can not even under washing conditions and the required flatness of the electronic system can be used because the associated Spring part, such. B. a spring bar, has a relatively large height, mechanically very sensitive and not sufficiently chemical or chemothermisch resis tent is. Also often used, via female headers with closely spaced contacts connectable flat conductor with on the surfaces arranged hermetically sealed electronics, the mechanical and climatic influences protected is not particularly washable on the contact side and robust enough.

The reference numerals used in the description of the general embodiment correspond to those described in the specific embodiments (hereinafter) described (US Pat. 1 to 10 ) be used.

According to the invention, the electronic flat system 1 as a base element a flat formed flat element 5 . 6 on whose surface at least one contiguous first area, hereinafter also as a dry area 2 in which all enclosed elements are not washed with washing liquid 18 come into contact, ie remain dry, and at least one contiguous second area, hereinafter also as a wet area 3 denotes, in which the exposed part of the terminal contacts located there 10 . 11 of washing liquid 18 is wet, that is wet, having. In this case, a subsection of the surface of the flat element is referred to as a coherent region 5 . 6 within which each surface point can be reached from any other surface point in at least one way (all surface points of the contiguous area are thus connected by at least one path which runs completely within this area). The surface can advantageously also each have several dry areas 2 and several wet areas 3 have, which do not overlap and which together form the exact total surface of the flat element.

In the following, if there are a plurality of dry areas and / or wet areas, the total dry area formed by all the dry areas is simplified as the dry area 2 designated (corresponding to wet areas). Whether the term "dry area" is intended to mean a single area or several combined (dry) areas results in each case for the person skilled in the art from the present context 2 or wet area 3 corresponding section of the flat element 5 . 6 (if necessary, including the associated enclosure 9 . 15 ) as a dry area 2 or wet area 3 designated; Here, too, results for the expert from the context, what exactly is meant.

According to the invention, the washable electronics flat system 1 in at least one definable water- or wash-resistant dry area 2 and at least one wet area 3 separated. This will be in the dry area 2 the electronic components 8th (electronics to be included) safely and dry enclosed as well as by a first enclosure 9 integrating wash-resistant sealed. Im at the dry area 2 adjacent wet area 3 become the fixed, biocompatible connection contacts 10a . 11a in their contact area or exposed section 10a-1 . 11a-1 fully exposed to the washing and disinfecting process and in their mounting area 10a-2 . 11a-2 together with the connecting cables 12 . 13 already with solder-stop paint 14 have a first application layer, on more delineated protective layers 15 protected (second enclosure). Dry and wet areas form for this purpose 2 . 3 over the protective covered connecting cables 12 . 13 , electrically connected, an electrical system in which a flat element 5 . 6 as a flexible, rigid or rigid flexible printed circuit board with the connection cables 12 . 13 for the connection contacts 10a . 11a and the electronics 8th pro rata in the dry area 2 and proportionally in the wet area 3 located.

The circuit board part 6 , also referred to below as a printed circuit board or printed circuit board element or flat element part, with electronics 8th in the dry area 2 is (by an enclosure 9 ) hermetically sealed. The circuit board part 5 , hereinafter also referred to as a printed circuit board, printed circuit board element or flat element part, with the connection contacts 10a respectively. 11a and their connecting cables 12 . 13 (to electronics 8th ) in the wet area 3 , up to the contact area (exposed portion) of the terminals 10a respectively. 11a enclosing by protective layers 15 is covered and protected and the circuit board side mounting area 10a-2 respectively. 11a-2 the connection contacts and parts of the connecting cables 12 . 13 is about these protective layers 15 also hermetically sealed. Here are dry and wet area 2 . 3 at the separation point or separation surface 4 over the hermetic closure (enclosure 9 ) of the drying area 2 and also about overlapping with the closure 9 below it (or between PCB part 5 and closure 9 ) extending protective layers 15 of the printed circuit board part 5 sealed.

The dry area 2 will be included the electronics 8th through a hermetically sealed enclosure 9 formed only on the surface with washing liquid 18 can be acted upon. This ensures that the electronics 8th that is completed in the enclosure 9 is functionally not affected and electrically only the wash-resistant terminal contacts 10a . 11a that with the electronics 8th over the circuit board 5 . 6 with their connecting cables 12 . 13 communicate and outside the dry area 2 in the wet area 3 lie proportionately in their free contact areas with the wash liquor 18 come in contact. The terminal contacts may be formed of nickel-free metal or a nickel-free metal alloy, wherein the contact surface preferably consists of a layer of white bronze (tin content preferably about 27% to 30%).

The circuit board parts 5 and 6 can, for example, via PCB connectors 7 be flexibly connected or articulated. In special embodiments, only a flexible or rigid or rigid-flexible circuit board 5 . 6 be present (plate elements 5 . 6 as exactly one part executed in one piece, if necessary then with flexible section 7 ). The circuit board 5 . 6 , in additional special embodiments also additionally segmentable, may, partially projecting, from the hermetically sealed dry area 2 stick out and thereby a wet area 3 form. Alternatively, the Nassbe rich 3 completely on the top or bottom of the PCB 5 . 6 be arranged and embedded in a completely surrounding him dry area or integrated. This may be the enclosure 9 the electronics 8th at the separation point or separation surface 4 to the wet area 3 sealing to the circuit board 5 . 6 nestle. On the surface of the wet area 3 are then the connection contacts 10a . 11a fixed in the exposed sections 10a-1 respectively. 11a-1 chemically or chemothermisch and physically claimed.

By separating the electronics flat system 1 in a dry and wet area 2 . 3 only the outer contours of the enclosure 9 the electronics 8th and the outer contour of the by means of protective layers 15 protected contact-carrying printed circuit board part 5 as well as the connection contacts 10a . 11a even with the washing liquid 18 surrounded and acted upon, wherein electrically only the contact area 10a-1 . 11a-1 the connection contacts, but not their attachment area 10a-2 . 11a-2 , with the washing liquid 18 communicates.

The circuit board 5 . 6 is in the wet area 3 designed so that the connection contacts 10a . 11a preferably freely accessible, in the contact area 10a-1 . 11a-1 Uncovered push buttons are those of the wash fluid 18 can be wetted freely, their electrical connection cables 12 . 13 to the electronics 8th (in the dry area 2 ) in the wet area 3 through protective layers 15 are covered, being in the wet area 3 a cover 15 is present, preferably with the same structure in the dry area 2 partially draws in. Here are the layers 15 to the outer contour of the push buttons 10a . 11a in their attachment area (at the connection position to the lines 12 . 13 ) and embed them there. For push-button spring parts 10a or other connection contacts with washable-wettable interior (or inner courtyard I), the layers 15 , guaranteed by an overflow recess 23 of the printed circuit board part 5 or by an overflow recess 24 of the connection contact 10a , into the interior I into it. This generally prevents local element formation. For an existing flat element-side drain 25 in the area of the connection contact 10a positioned a flow barrier 26 the layer 15 (see later 7 to 10 ).

The protective layers 15 Cover except the top surfaces or flat sides of the circuit board 5 also their front sides and protect them from alkali influence and water absorption. This is the complete circuit board 5 in the wet area 3 chemically or chemothermally resistant. This also ensures the use under extreme environmental conditions (heat, cold, humidity, elevated air pressure, tropical climate, sweat, etc.). In the dry area 2 are the protective layers 15 the circuit board 5 only überleitend available and can with increasing distance from the separation point or separation surface 4 largely eliminated. Here the enclosure provides 9 , which the flat sides and end faces of the circuit board 5 , starting from the separation point or separating surface 4 , surrounds and including the electronics 8th hermetically seals, for the conclusion of the invention.

The guarantee of body compatibility are preferably nickel-free push buttons as connection contacts 10a . 11a and to further increase reliability, the wash-resistant, robust, and chemically or chemothermally resistant snaps are preferably on the circuit board 5 soldered (only pushbutton spring part 10a and push button ball part 11a without riveting), which prevents local chemical reactions by rivet tearing and their surface destruction and leads to a particularly low height. For soldered connection contacts 10a . 11a Reliability is further supported when the surface of the terminals 10a . 11a consists of a layer of white bronze.

To protect the solder joint from suds 18 this is in their environment between the attachment area 10a-2 . 11a-2 the connection contact and the circuit board 5 by simple or multiple protection serving 15 sealed and thus hermetically sealed. This also includes the hermetic protection of the connecting cables 12 . 13 on the circuit board 5 one.

About these push buttons 10 . 11 the adaptive signal and energy transmission takes place via external electrical supply lines 17 , which are connected separately and also in flexible textile element 16 can be integrated, with an overall very low height and the contact pairing (terminals and associated counterparts on the leads 17 ), with the push button counterparts 10b . 11b with the snaps 10a . 11a the circuit board 5 can remain connected in the washing process. This mainly affects supply lines 17 for devices, electrodes, sensors etc. or the interconnection of several partial electronic flat systems. The electrical connection modification of the electronics flat system 1 is done by type, number and arrangement of the push buttons 10a . 11a , about all with the electronics 8th to be connected electrical leads 17 as signal lines and power lines (connection energy source 20 ) or other electronic flat systems contacted and solvable with the connection contacts 10a . 11a on the circuit board 5 (Button pairing).

This results in the inventive solution of the electronic flat system 1 and its modifiability in releasable or inseparable connection with the textile element 16 of the textile / Flexgebildes under preferential use of snaps 10 . 11 as connection contacts, in particular from a proportionate (in the wet and dry area 2 . 3 ) electronics and pushbutton populated printed circuit board 5 . 6 with electronics and pushbutton-related delimited stratified or layered cover (enclosure 9 , Protective layer 15 ) of electronics 8th , their connecting cables 12 . 13 , Supports (circuit board parts 5 . 6 ) to the connection positions 10a-2 . 11a-2 the push buttons, their contact area 10a-1 . 11a-1 for the realization of the contact pairing of the protective layer 15 is excluded. Here are the connection contacts 10a . 11a protective in the attachment area 10a-2 . 11a-2 embedded, but so that a contact pairing is always guaranteed. It is irrelevant whether the cover layers 9 . 15 the proportionate PCB surfaces 5 . 6 consist of the same or different material and whether their design is the same or different.

This also includes very diverse, special solutions for the waterproof flexible or rigid leak-free enclosure 9 the electronics 8th in the dry area 2 one that ensures the electronics 8th remains dry during operation and washing (eg encapsulation or potting). For flexible, foil-like pocket-shaped water-resistant housing of the electronics 8th lets the seal 9 the circuit board 5 . 6 advantageously by clamping the film (eg polyurethane) itself over the circuit board 5 . 6 at the separation point 4 , taking advantage of the elastomeric sealing properties of the film realize. For a rigid capsule-shaped enclosure 9 (eg, plastic housing) is an additional seal that fits the prismatic, tolerant cross-section of the PCB 5 . 6 encloses and their clamping at the separation point 4 allows, required. A split housing 9 can also be advantageous over a closed sealing system in the dividing surface and in the separating surface 4 hermetically seal. When housing the electronics 8th By casting with a potting compound (eg elastomeric potting) eliminates an additional clamping at the separation point 4 because the potting compound advantageously seals these itself. In such a potting z. B. for medical applications also advantageous electrodes 21 , z. As ECG, EMG, EEG, impedance electrodes and other control and functional elements 22 Embedded, sealed, with the connecting cables 12 . 13 are permanently connected.

Basis of the electronic flat system according to the invention 1 forms a flat formed flat element 5 . 6 , This flat element consists of two individual, rigid circuit boards 5 and 6 , which are arranged side by side in the flat plane and a flexible connecting element 7 are flexible or articulated connected. In other versions, this can also be a rigid flex PCB without PCB connector 7 be used (see 3 to 6 : 7 then designates a flexible section of the rigid-flex circuit board 5 . 6 ). On the top of the first circuit board element 6 is a the PCB element 6 partially covering, electrically conductive layer for the formation of electrically conductive connection lines 12 . 13 arranged. Also above the PCB element 6 and adjacent to this are the electronic components 8th arranged. These are z. For example, components for an MP3 player; however, other electronic components are also conceivable. These are connected to the conductor elements (connection cables 12 . 13 ) electrically conductively connected.

The electrical connection cables 12 . 13 of the first printed circuit board part 6 are over the electrically conductive connector 7 with accordingly on the second circuit board part 5 above the same arranged electrically conductive connecting lines 12 . 13 connected. The ladder elements 12 . 13 or the corresponding connecting line layers consist here of two superposed individual layers of copper (lower, the circuit board element 5 facing arranged layer 12 ) and tin (overlying layer 13 ). On this second circuit board element 5 are the connection cables 12 . 13 embedded and above this conductor element 12 . 13 electrical connection contacts 10a (in the form of a push button spring part, see advantageous embodiments 7 to 10 ) and 11a arranged (in the form of a push button ball part). The two snap fastener parts 10a . 11a are here above the PCB element 5 and laterally juxtaposed with the lead layers 12 . 13 electrically connected. This is the consistent contact of the electronics flat system 1 guaranteed. For the sake of simplicity, the connection contacts 10a without bottom section BI and without washing liquid 18 drawn in the interior I (for details see 7 to 10 ).

According to the invention, the flat element is in the flat plane 5 . 6 of the electronics flat system 1 now in two separate areas, the drying area 2 and the adjacent wet area 3 divided up. The two areas abut each other directly (separation point or separation surface) 4 ). In the dry area 2 is the flat element 5 . 6 at the top (including the enclosed electronic components 8th and the connector 7 ), on the front sides or narrow sides and on the underside opposite the upper side completely from a first enclosure 9 (here: rigid plastic housing) surrounded. In other advantageous embodiments, the first enclosure 9 of the dry area 2 z. B. be formed by massive, flexible potting. The enclosure 9 closes here to the elements 8th . 6 . 7 so immediately adjacent that they are hermetically sealed to the outside. As described in more detail below, a to the circuit board element 6 remote portion of the printed circuit board element 5 including the attachment sections 10a-2 . 11a-2 the connection contacts 10a . 11a through a protective layer 15 also hermetically sealed. The protective layer 15 is this on the top of the PCB element 5 , arranged on the narrow or end sides and on the underside so that the on the circuit board element 5 arranged connecting cables 12 . 13 , the electrical connection points or attachment points 10a-2 . 11a-2 and the exposed portions of the circuit board element 5 completely enclosed and hermetically sealed. This concerns in further embodiments with differently shaped connection contacts also possible interiors I of the connection contacts 10a (please refer 7 to 10 ). For a hermetic sealing of all elements 8th . 5 . 6 . 7 and the attachment sections 10a-2 and 11a-2 to ensure are in the area of the separation point 4 the protective layer 15 as well as the enclosure 9 , seen in the direction perpendicular to the plane, partially superimposed or overlapping arranged (the protective layer 15 In this case it is partly below the first enclosure 9 between this and the circuit board element 5 embedded). In the present case, of the two lying side by side on the circuit board element 5 arranged connection contacts 10a . 11a the connection contact shown on the left 10a designed as a push button spring part of a push button, the connection contact 11a as a push button ball part of a push button. The lower portion of the respective push button part is in this case of the protective layer 15 so bordering that the attachment area 10a-2 respectively. 11a-2 with the connecting cables 12 . 13 and an overlying portion are hermetically sealed to the outside. Only the upper part 11a-1 respectively. 10a-1 the push-button parts 10a . 11a is exposed, not through the protective layer 15 covered.

The external connection lines 17a , b can thus be detachable via their corresponding pushbutton part counterparts 11b . 10b with the push-button parts 10a . 11a of the electronics flat system 1 get connected. Also the connection contact 10b is for simplicity's sake without washing liquid 18 drawn in the interior I.

In the present case, the electronics flat system 1 including the above-described components in the interior of a textile element 16 (for example, a garment) integrated. Only the connecting cables 17a , b are only partially in the element 16 integrated. In a washing process (shown: washing liquid 18 ), in which the electronic flat system 1 and the garment 16 are exposed to a cleaning liquid, are thus of the electronics flat system 1 only the surface of the enclosure 9 , the protective layer 15 and the upper sections (exposed sections 10a-1 and 11a-1 ) of the electrical connection contacts 10a and 11a subjected to wetting with liquid. All other components of the electronics flat system 1 (except for the separate connecting cables 17a , b with their likewise hermetically sealed connection contacts 10b and 11b ) are opposite to the washing liquid 18 hermetically sealed.

The circuit board 5 wears in the wet area 3 as terminal contacts the push-button spring part 10a and the push button ball part 11a , which are designed to ensure biocompatibility nickel-free. The wiring on the circuit board 5 to the push-button spring part 10a and to the push button ball part 11a is a delineated conductor from the laminated copper layer 12 and one over this copper layer 12 lying and this covering tin layer 13 realized. This will be the dry area 2 with the wet area 3 electrically connected. In the embodiment, the out of the delimited copper layer 12 and the tin layer 13 existing connecting line in one layer on one side of the circuit board 5 realized.
