Description
Die Erfindung betrifft eine Anordnung gemäß Oberbegriff des Anspruchs 1. Hochpolymerfolien (z. B. aus Polyvinylfluorid) zeigen piezoelektrische Eigenschaften, die — im Gegensatz zu piezokeramischen Werkstoffen — sich für unkonventionelle physiologischmechai.ische Anwendungen anbieten.The invention relates to an arrangement according to the preamble of claim 1. made of polyvinyl fluoride) show piezoelectric properties, which - in contrast to piezoceramic Materials - opt for unconventional physiological-mechanical Offer applications.
Dabei werden elektrische Ladungen frei, wenn diese Folien verformt werden. Durch Metallisierung der Oberfläche entsteht ein Kondensator, dessen Ladung durch den piezoelektrischen Effekt hervorgerufen wird. Diese Eigenschaften piezoelektrischer Folien werden schon benutzt zur Konstruktion von Mikrophonen, Lautsprechern (Sessler G. M., Fortschritte der Akustik, DAGA76, S. 81 —95) und auch zur Messung physiologischer Größen (Elastokardiogramm) Süssner H., Dissertation München 1976). Weiterhin sind intrakorporal angeordnete Geräte, z. B. Herzschrittmacher, mit Batteriebetrieb bekannt. Da Batterien aufgeladen werden müssen, soll eine Stromversorgung, die ohne eine wiedereinsetzbare Batterie auskommt, geschaffen werden.This releases electrical charges when these foils are deformed. By metallizing the A capacitor is created on the surface, the charge of which is caused by the piezoelectric effect. These properties of piezoelectric foils are already used for the construction of microphones, Loudspeakers (Sessler G. M., Progress in Acoustics, DAGA76, pp. 81-95) and also for measuring physiological Sizes (elastocardiogram) Süssner H., dissertation Munich 1976). Furthermore are intracorporeal arranged devices, e.g. B. cardiac pacemaker known with battery operation. Because batteries are charged need to be, a power supply that works without a reusable battery is to be created will.
Erfindungsgemäß geschieht dies durch eine Anwendung nach dem Kennzeichen des Anspruchs 1; vorteilhafte spezielle Anwendungen sind in den Unteransprüchen angegeben.According to the invention, this is done by an application according to the characterizing part of claim 1; advantageous special applications are specified in the subclaims.
Soll z. B. ein Teil der vom Herzmuskel erzeugten mechanischen Energie, die eine pulsierende Dehnung der Arterien zur Folge hat, in elektrische EnergieShould z. B. a part of the mechanical energy generated by the heart muscle, which is a pulsating stretch the arteries result in electrical energy
ίο umgewandelt werden, kann sie durch eine geeignete Anbringung der Folie (Umwicklung) an einer Arterie erfolgen; es können auch ganze Körperteile, z. B. das Handgelenk, umwickelt werden.ίο can be converted by an appropriate one Applying the film (wrapping) to an artery; whole body parts can also be used, e.g. B. that Wrist, to be wrapped.
Falls Kombinationen (Serienschaltung und/oder Par-If combinations (series connection and / or par-
'5 allelschaltung verwendet werden sollen, können die Folien mit Kontaktdrähten oder -streifen versehen und durch einen leitenden Kleber oder Lotung mit niedrig-schmelzendem Lot galvanisch miteinander verbunden werden.'5 allele circuit should be used, the Foils provided with contact wires or strips and with a conductive adhesive or soldering low-melting solder are galvanically connected to one another.
Es wird dabei der transversale piezoelektrische Effekt der senkrecht zu den Oberflächen polarisierten Folie ausgenutzt. Vorteilhaft erscheint die Anwendung besonders dünner Folien: Wegen der größeren Kapazität ist die bei gleicher Dehnung erzeugte piezoelektrisehe Energie größer. Außerdem ist die für den piezoelektrischen Effekt maßgebende mechanische Spannung umso größer, je dünner die Folie ist bei gleicher wirksamer Kraft und gleicher Oberfläche der Folien.It becomes the transverse piezoelectric effect exploited the film polarized perpendicular to the surfaces. The application appears to be advantageous Particularly thin foils: Because of the greater capacity, the piezoelectric generated with the same expansion is high Energy bigger. In addition, the mechanical one that is decisive for the piezoelectric effect The tension is greater, the thinner the film is with the same effective force and the same surface Foils.
Insbesonders kann man mit der dadurch erzeugten elektrischen Energie einen Herzschrittmacher über einen kleinen, als Pufferspeicher dienenden, aufladbaren Akkumulator mit Strom versorgen. Dadurch ist ein Auswechseln einer Batterie mit begrenzter Lebensdauer nicht nötig.In particular, you can use the electrical energy generated by a cardiac pacemaker supply a small, rechargeable accumulator, which serves as a buffer storage, with power. This is a There is no need to change a battery with a limited service life.
Eine weitere Anwendung des Erfindungsgedankens liegt darin, intrakorporal angeordnete Meßfühler, die eine Stromversorgung benötigen und physiologische Funktionen des Körpers überwachen, durch derartige Folienwandler unabhängig von äußerer Energiezufuhr zu machen.Another application of the concept of the invention lies in intracorporeally arranged measuring sensors, the need a power supply and monitor physiological functions of the body through such To make foil transducers independent of external energy supply.
Auch die Auslösung physiologisch bedingter Vorgänge (z. B. das Öffnen eines Magnetventils, mit dem eine Harnblasenprothese ausgerüstet ist), kann mit Hilfe eines elektrischen Energiespeichers erfolgen, der von einem Folienwandler gespeist wird.The triggering of physiologically conditioned processes (e.g. opening a solenoid valve with which one Urinary bladder prosthesis), can be done with the help of an electrical energy storage device that is powered by a foil transducer is fed.
