Definitions
- the invention relates to an electromechanical transducer with a plurality of superimposed films of a
- electroactive polymer and with superimposed, applied to the films electrodes, each with
- At least one contact lug are provided.
- Electromechanical transducers are in manifold
- electroactive layers each carrying an electrode with a contact lug.
- the contact lugs terminate with outer walls of the converter and can be interconnected there.
- dielectric elastomer with superimposed, applied to the foil electrodes, each with
- At least one contact lug are provided, acc. of
- U-shaped is fixed to a stack of slides.
- Another advantage is that the polymer strip is prestressed. As a result, this one can move at one
- Fixing of the polymeric strip may be through an end cap and / or through an encapsulation, as further discussed below.
- the electrodes are connected in a simple but reliable manner and the connections are optionally fixed for further electrical connection and / or mechanical loading.
- life of the actuator is increased compared to the conventional, rigid interconnection of the terminal lugs and the dynamics of the transducer significantly improved by the prestressed and elastic polymer strip. If there are contact lugs on more than two sides, which are interconnected by polymer strips provided with electrodes, the dynamics of the transducer are likewise improved, since the electrical charge can be applied more quickly to the individual transducer foils. Also, such a contact can be made of contact lugs of sensors. It can be provided that an electrical
- connection rod-shaped formed in the polymer strip is rolled. As a result, the electromechanical
- protective cap can still be provided.
- Another alternative is a strip-like
- strip-like trained connection such as sheet metal
- strip-like trained connection can also experience greater mechanical stress than, for example, a rod-like trained.
- an end cap is provided in a transducer having a strip-like terminal or a crimped-crimped type, the fixing of the polymer strip and terminal in a slot in the end cap may be accomplished
- the electromechanical transducer according to the invention can be encapsulated to improve its mechanical stability, to protect against environmental influences, as a contactor and in particular for fixing the polymer strip to the stack.
- Such an encapsulation can take place by wrapping around at least one axis with at least one strip of polymer film.
- An alternative is one
- Encapsulation by a wound-elastic cap made of a polymer material This is spent stretched over the stack and the polymer strip with the at least one electrode of the individual film layers and holds after

- Contact lugs 4 is a polymer bonding strip 7 gem.
- Fig. 3 is provided, which has two spaced electrodes 8,9.
- the one contact lug 4 can, depending on
- the polymer contacting strip 7 is held in Fig. 1 by a further strip 10 of a polymer film in contact with the film stack 11, the gem. Fig. 10 the film stack 11 and the polymer bonding strip 7 wraps around.
- Connections can be formed almost arbitrarily, for example, like a clamp or as explained with reference to Figures 4 to 7.
- FIG. 4 shows, in a side view, a polymer strip 12 with two spaced-apart electrodes 13, 14 for contacting opposite contact lugs in an electromechanical converter, cf. FIGS. 1 and 2.
- the polymer strip 12 is two bar-shaped
- trained terminals 15,16 for example, formed by wires or pins, the electrodes 13,14 curled contacting.
- FIG 6. An alternative for holding rod-shaped terminals 23,24 is shown in FIG 6. There, the polymer strip 25 overlaps with the ends rolled-up terminals 23,24 the end cap 26 and the rod-shaped terminals 23,24 in the upper side of
