01.01.1970 //Engineers created special polymer for the artificial muscles of robot
Scientists from the university of Japan they created new material for the artificial muscles of robots for creating such muscles they frequently use electroactive polymers. One of similar EAP they decided to improve Japanese scientists. "our material is the dielectric elastomer (one of the types EAP). Now such materials known several, but our is the original mixture of the self-organizing (at the molecular level) polymer (block copolymer) and the oligomer ", says Spontak.
The key advantages of this "mix": small price, ease and the high strength of material. "scientific literature is overfilled by articles about the tests of the effectiveness of material- candidates for the title of artificial muscle the advantage of our approach in the fact that we thoroughly select the mixture of different components for obtaining the material with the assigned (and by the most varied) properties", is added Ford.
Artificial muscle for the robot - this undoubtedly good, but can this material be used as the implant in the human body - unclearly. Scientists show that their materials manifest the large tension (more than 200%) during the application of the considerably small electric field (less than 40 volts to the micrometer). From the material- predecessors it was possible to attain only 50% of tension during the application of field of more than 50 V/ m. But also this yet not all. "new material manifests the salient electromechanical properties, its effectiveness of the conversion of electric field energy into the mechanical work exceeds 90% (thus far this maximum reaching in this region) and in this case it does not lose its properties even after many cycles of work", is added Ford.
Such materials can be used for the creation of the small flying and creeping mechanisms, the "reacting" cloths, controlled catheters, different micropumps and other biomedical devices, other equipment models. Let us note also that the creators of new material, certainly, dream, that their development will help the creators of artificial hand to win in the contest on armrestling between the people and the robots.
