Abstract

Electronic components that include sensors, consist of a biopolymer and can be converted to scrap by biodegradation.

Description

Die Erfindung ist in der gesamten Elektronik einsetzbar. The invention is applicable to the electronics.

Bekannt sind elektronische Bauelemente, die von der Funktion her mit unterschiedlichsten Materialien aufgebaut sind. are well known electronic components, which are constructed in function with different materials. Die Entwicklungsziele orientieren auf die Erfüllung der Funktion in hoher Qualität, eine möglichst große Lebensdauer und eine preiswerte Herstellung. The development goals are based on the performance of the function in high quality, longest possible service life and low-cost production.

Erreicht ein damit aufgebautes Gerät das Ende seiner Lebensdauer oder soll es entsorgt werden, so ist der anfallende Elektronikschrott schwer zu vernichten, zu recyclen oder sonst wie zu verwenden. Reached thus constructed device, the end of its life or is it to be disposed of, the accumulated e-waste is difficult to eradicate, to recycle or otherwise use.

Aufgabe der Erfindung ist, Elektronikbauelemente zu finden, die die Entsorgung einfach gestalten. The object of the invention to find electronic components which simply make the disposal.

Die Erfindung ist dadurch gekennzeichnet, daß elektronische Bauelemente einschließlich dazugehörender physikalischer, chemischer, biologischer Sensoren auf der Grundlage biologisch abbaubarer Biopolymere wie Poly-β-Hydroxybuttersäure (PHB) oder ihren Copoly meren oder Mischungen mit diesen oder weiteren Vertretern der Poly-β-Hydroxyfettsäuren realisiert sind. The invention is characterized in that electronic components including thereto belonging physical, chemical, biological sensors based on biodegradable biopolymers, such as poly-β-hydroxybutyric acid mers (PHB) or its copoly or realized mixtures with these or other representatives of the poly-β-hydroxy fatty acids are. Diese sind biologisch mit Mikroorganismen oder Pflanzen herstellbar und werden auch durch Mikroorganismen und Enzyme abgebaut. These are biologically produced with microorganisms or plants and are degraded by microorganisms and enzymes. Von den elektronischen Bau elementen bleiben nach dem biologischen Abbauprozeß nur Dotierungs-, Legierungs-, Mischungs- und/oder Beschichtungsmaterialien übrig. Of the electronic construction elements remain after biodegradation process only doping, alloying, mixing and / or coating materials left. Deren Anteil am elektronischen Bau element ist in der Regel verschwindend klein. Their share of electronic construction element is vanishingly small in general.

Der biologische Abbauprozeß für eine Verschrottung kann auf dem Komposthaufen erfolgen oder aber in einer dafür eingerichteten Anlage. The biodegradation process for scrapping can be done on the compost heap or in a purpose-built plant. Es können auch Depots in den Elektronik bauelementen oder in ihrer Nähe eingerichtet sein, die den Abbau nach Initialisierung in Gang bringen. It can also depots components in the electronics or be set up in its vicinity which bring the degradation after initialization started. Die Initialisierung kann sowohl durch einen Wärmeimpuls als auch durch einen kombinierten Wärme-Feuchte-Impuls ausgelöst werden. The initialization can be triggered either by a heat pulse and by a combined heat and humidity pulse. Die Feuchte kann dabei durch Einstellen des Taupunktes oder durch eine chemische Reaktion mit Wasserabspal tung besorgt sein. The humidity can thereby be worried by adjusting the dew point or by a chemical reaction with Wasserabspal tung.

Die Erfindung soll nachfolgend an Beispielen erläutert werden. The invention will be explained in the following examples.

Fig. 1 zeigt den Aufbau und den Abbau von PHB, wobei die Enzyme β-Ketothiolase ( 1 ), NADPH-abhängige Acetoacetyl-CoA-Reduktase ( 2 ), NADH-abhängige Acetoacetyl-CoA- Reduktase ( 3 ), P(3HB)/PHF-Synthase ( 4 ), P(3HB)/PHF-Depolymerase ( 5 ), D-(-)-β-Hydroxy buttersäure-Dimer-Hydrolase ( 6 ), D-(-)-β-Hydroxybuttersäure-Dehydrogenase ( 7 ) und Aceto acetyl-CoA-Synthase ( 8 ) wirksam sind. Fig. 1 shows the structure and degradation of PHB, wherein the enzymes β-ketothiolase (1), NADPH-dependent acetoacetyl-CoA reductase (2), NADH-dependent acetoacetyl-CoA reductase (3), P (3HB) / PHF synthase (4), P (3HB) / PHF depolymerase (5), D - (-) - β-hydroxy butyric acid-dimer hydrolase (6), D - (-) - β-hydroxybutyric acid dehydrogenase ( 7) Aceto acetyl-CoA synthase (8) are effective.

Fig. 2 zeigt ein allgemeines Substrat ( 9 ) aus PHB. Fig. 2 shows a general substrate (9) made of PHB. In dieses Substrat sind durch Laser Löcher gebohrt, die durch Verkupferung, Graphitierung oder Laserumwandlung leitend ge macht wurden ( 10 ). In this substrate, holes are bored by laser, which makes conductive ge by copper plating, or laser graphitization conversion was (10). Der Abbau erfolgt zunächst durch eine Depolymerase, die das Makro molekül in Monomere und einen gewissen Anteil (15-20%) von Dimeren der Hydroxy buttersäure zerlegt. The degradation is first (15-20%) of dimers of the hydroxy butyric decomposed by a depolymerase, the molecule in the macro monomers and a certain proportion. Durch eine spezifische D-(-)-β-Hydroxybuttersäure-Dimer-Hydrolase wird die Spaltung des Hydroxybuttersäure-Dimers katalysiert. By a specific D - (-) - β-hydroxybutyrate-dimer hydrolase cleavage of the hydroxybutyric acid dimer is catalyzed. Die entstandenen Monomere, dh Hydroxybuttersäure-Moleküle fließen über eine ATP-verbrauchende, durch die Acetyl- CoA-Synthase katalysierte Reaktion wieder in den Acetyl-CoA-pool der Zelle ein. The resulting monomers, ie hydroxybutyric acid molecules flow through an ATP-consuming, by the acetyl-CoA synthase catalyzed reaction back into the acetyl-CoA pool of the cell. Damit steht dieses Molekül dem zentralen C-Metabolismus der Mikroorganismuszelle zur Verfügung und kann zum Aufbau von zelleigenen Strukturen (Biomasse) oder zur Energiegewinnung ge nutzt werden. Thus, this molecule is the central carbon metabolism of the microorganism cell is available and can be utilized for the construction of the cell's own structures (biomass) or for energy ge.

In letzterem Fall erfolgt letztlich über den Tricarbonsäure-Zyklus (TCA-Zyklus) und die Atmungskette der Abbau zu Kohlendioxid (CO 2 ) und Wasser. In the latter case, ultimately via the tricarboxylic acid cycle (TCA cycle), and the respiratory chain degradation to carbon dioxide takes place (CO 2) and water. Da das PHB-Molekül nur aus den Atomen C, O und H besteht, können beim vollständigen Abbau nur CO 2 und Wasser entstehen. Since the PHB molecule consists only of the atoms of C, O and H, in the complete degradation only CO 2 and water can occur. Übrig bleiben minimale Mengen der leitenden Bahnen ( 10 ). Remain minimal amounts of conductive traces (10).

Fig. 3 zeigt ein Substrat wie in Fig. 2 aber mit einer Schicht aus einem leitenden Polymer ( 11 ), z. Fig. 3 shows a substrate such as in Fig. 2 but with a layer of a conductive polymer (11), z. B. Poly(2,5-furylen-vinylen) (PFV). As poly (2,5-furylene vinylene) (PFV). Dieses regiert auf bestimmte Gase durch eine Leitfähigkeitsänderung und ist damit ein Gassensor. This ruled to certain gases through a change in conductivity, making it a gas sensor.

Fig. 4 zeigt schematisch auf einem Substrat nach Fig. 2 eine mäandrierende Widerstands bahn ( 12 ) und eine laterale Kapazität ( 13 ). Fig. 4 schematically shows on a substrate of FIG. 2 is a meandering resistor track (12) and a lateral capacity (13).

Fig. 5 zeigt ein Substrat nach Fig. 2 mit zwei verschiedenen ionensensitiven Elektroden ( 14 ) und ( 15 ). Fig. 5 shows a substrate of FIG. 2 with two different ion sensitive electrode (14) and (15).

B. for detecting a pH value by means of irradiation by a light source.

Fig. 7 zeigt ein Substrat aus PHB wie in Fig. 6 mit eingelagerten Farbreaktionen zeigenden Enzymen ( 17 ). Fig. 7, a substrate of PHB as in Fig. 6 displayed with incorporated color reactions enzymes displays (17). Bei Durchstrahlung und Einwirkung einer zu messenden Konzentration ändert sich das Spektrum. In irradiation and exposure to a concentration to be measured, the spectrum changes. Das kann für einen Sensor genutzt werden. This can be used for a sensor.

Fig. 8 zeigt auf einem PHB-Substrat aufgebrachte Leiterbahnen ( 18 ) aus Kupfer und Lötbums ( 19 ) aus leitfähigem Kleber. Fig. 8 shows a PHB substrate applied conductor tracks (18) of copper and Lötbums (19) of conductive adhesive.

Fig. 9 zeigt die Ausgestaltung eines PHB-Substrats als Gehäuse ( 20 ) mit innen geführten Leiterbahnen ( 21 ) und nach außen geführten Verbindungen ( 22 ). Fig. 9 shows the configuration of a PHB-substrate as a housing (20) having inwardly directed conductor tracks (21) and guided outwardly compounds (22).
