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 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]. A torsional actuation from highly twisted fibers was demonstrated for the first time in [2].

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.

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. In summary, the criteria include stress , strain , strain rate , cycle life, and elastic modulus.

 Сьюзан, - позвал он, задыхаясь.  - Ты должна помочь мне выбраться отсюда. Она ничего не понимала.

У нас нет времени, чтобы… - Никакая служба здесь не появится, Сьюзан. У нас столько времени, сколько. Сьюзан отказывалась понимать. Не появится.

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.


Не было видно даже кнопочных электронных панелей на дверях кабинетов. Когда ее глаза привыкли к темноте, Сьюзан разглядела, что единственным источником слабого света в шифровалке был открытый люк, из которого исходило заметное красноватое сияние ламп, находившихся в подсобном помещении далеко внизу. Она начала двигаться в направлении люка. В воздухе ощущался едва уловимый запах озона. Остановившись у края люка, Сьюзан посмотрела .

Sulla Vespa. Venti mille pesete. Итальянец перевел взгляд на свой маленький потрепанный мотоцикл и засмеялся.

 Дэвид. - Это Стратмор, - прозвучал знакомый голос. Сьюзан плюхнулась обратно в ванну. - Ох! - Она не могла скрыть разочарование.

Сигналы тревоги гремели подобно грому. Коммандер посмотрел на вышедший из строя главный генератор, на котором лежал Фил Чатрукьян. Его обгоревшие останки все еще виднелись на ребрах охлаждения.

 - Простите. Беккер вытащил из вазы, стоявшей на столике в центре комнаты, розу и небрежно поднес ее к носу, потом резко повернулся к немцу, выпустив розу из рук.
