File Name: artificial muscles from fishing line and sewing thread .zip
An international team led by The University of Texas at Dallas has discovered that ordinary fishing line and sewing thread can be cheaply converted to powerful artificial muscles. The new muscles can lift a hundred times more weight and generate a hundred times higher mechanical power than the same length and weight of human muscle. Per weight, they can generate 7. The powerful muscles are produced by twisting and coiling high-strength polymer fishing line and sewing thread. The muscles are powered thermally by temperature changes, which can be produced electrically, by the absorption of light or by the chemical reaction of fuels. Twisting the polymer fiber converts it to a torsional muscle that can spin a heavy rotor to more than 10, revolutions per minute. Subsequent additional twisting, so that the polymer fiber coils like a heavily twisted rubber band, produces a muscle that dramatically contracts along its length when heated, and returns to its initial length when cooled.
The application claims priority under 35 U. A field of the invention is artificial muscles. Applications of the invention include any application in which actuators are used, and especially in applications where low weight, fine motion and high contractile work are required, including, for example, robotics and prosthetics. Twisted and coiled fibers have been recently proposed as a new class of artificial muscles . A torsional actuation from highly twisted fibers was demonstrated for the first time in .
These artificial muscles utilize non-coiled or coiled yarns and can be either neat or comprising a guest. Devices comprising these artificial muscles are also described. Patent Appl. These patent applications are hereby incorporated by reference in their entirety for all purposes. This invention was made with government support under Grant Nos. N awarded by the Office of Naval Research. The government has certain rights in the invention.
Toward an Artificial Muscle In designing materials for artificial muscles, the goals are to find those that will combine high strokes, high efficiency, long cycle life.

Она была потрясена. Прямо перед ней во всю стену был Дэвид, его лицо с резкими чертами. - Сьюзан, я хочу кое о чем тебя спросить. - Звук его голоса гулко раздался в комнате оперативного управления, и все тут же замерли, повернувшись к экрану.
Я был там, внизу. Резервное питание подает слишком мало фреона. - Спасибо за подсказку, - сказал Стратмор.
Хорошо бы их вытянуть. Терпи, - сказал он. - Терпи. Потом закрыл глаза и глубоко вздохнул. Беккер не сразу почувствовал, что его кто-то подталкивает. Подняв глаза, он увидел старика с усыпанным родинками лицом, который стоял перед ним, намереваясь пройти. Беккера охватила паника.
