Twisting strong fibres such as sewing thread and fishing line produces artificial 'muscles' that are stronger than their human counterparts.

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.

Muscles made from thread

Artificial muscles , also known as muscle -like actuators , are materials or devices that mimic natural muscle and can change their stiffness, reversibly contract, expand, or rotate within one component due to an external stimulus such as voltage, current, pressure or temperature. Conventional motors and pneumatic linear or rotary actuators do not qualify as artificial muscles, because there is more than one component involved in the actuation. Due to their high flexibility, versatility and power-to-weight ratio compared with traditional rigid actuators, artificial muscles have the potential to be a highly disruptive emerging technology. Though currently in limited use, the technology may have wide future applications in industry, medicine, robotics and many other fields. While there is no general theory that allows for actuators to be compared, there are "power criteria" for artificial muscle technologies that allow for specification of new actuator technologies in comparison with natural muscular properties.

High-performance robotic muscles from conductive nylon sewing thread Abstract: Natural muscles exhibit high power-to-weight ratios, inherent compliance and damping, fast actuation and high dynamic ranges. Unfortunately, traditional robotic actuators have been unable to attain similar properties, especially in a slender muscle-like form factor. Recently, super-coiled polymer SCP actuators have rejuvenated the promise of an artificial muscle.

Artificial Muscles from Fishing Line and Sewing Thread

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 [1].

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.

Я хочу уничтожить все следы Цифровой крепости до того, как мы откроем двери. Сьюзан неохотно кивнула. План неплохой. Когда служба безопасности извлечет Хейла из подсобного помещения и обвинит в убийстве Чатрукьяна, он скорее всего попытается шантажировать их обнародованием информации о Цифровой крепости. Но все доказательства к этому моменту будут уничтожены, и Стратмор сможет сказать, что не знает, о чем речь. Бесконечная работа компьютера. Невзламываемый шифр.

 Увы, я не знаю, как это делается. Я вызвал скорую. Беккер вспомнил синеватый шрам на груди Танкадо. - Быть может, искусственное дыхание делали санитары. - Да нет, конечно! - Клушар почему-то улыбнулся.  - Какой смысл хлестать мертвую кобылу.

 Я обошел программу Сквозь строй, - простонал коммандер. - Но вы же не знали. Стратмор стукнул кулаком по столу. - Я должен был знать. Да взять хотя бы его электронное имя.  - Боже мой, Северная Дакота. Сокращенно NDAKOTA.

С тех пор их отношения развивались с быстротой скольжения по склону горы. ГЛАВА 4 Потайная дверь издала сигнал, выведя Сьюзан из состояния печальной задумчивости. Дверь повернулась до положения полного открытия. Через пять секунд она вновь закроется, совершив вокруг своей оси поворот на триста шестьдесят градусов.

Стратмор приближался к ней, его лицо казалось далеким воспоминанием. Холодные серые глаза смотрели безжизненно. Живший в ее сознании герой умер, превратился в убийцу. Его руки внезапно снова потянулись к ней в отчаянном порыве.

Зачем им переходить на Цифровую крепость. Стратмор улыбнулся: - Это. Мы организуем утечку секретной информации. И весь мир сразу же узнает о ТРАНСТЕКСТЕ. Сьюзан вопросительно смотрела на .

 Конечно. Так, чтобы не осталось и следа. Сьюзан нахмурилась.
