The muscle wires brand name includes a wide range of shape memory alloy kits, books and more. Just as the brand wonder® represents a wide range of bread, rolls and more, the muscle wires name covers a range of shape memory alloy products. The best-selling muscle wires project book has provided clear and useful.
The niti 150 micron diameter shape memory alloy artificial muscle wires are used here. Shape memory alloy wireshave the characteristic of contracting when a voltage is applied to them. Shape memory alloys possess the ability to undergo shape change at low temperature and retain this deformation until they.

Abstract this paper presents a flexible artificial muscle actuator using coiled shape memory alloy (sma) wires. The actuator mainly consisted of flexible materials and sma wires and the fabrication was based on molding of silicon rubber. The actuator was also characterized by the motion with the body in flexion.

Shape memory alloys (sma's) are metals, which exhibit two very unique properties, pseudo-elasticity, and the shape memory effect. Arne olander first observed these unusual properties in 1938 (oksuta and wayman 1998), but not until the 1960's were any serious research advances made in the field of shape memory alloys.
Nitinol is one of several alloys which demonstrate the shaped memory effect. When cool these alloys can be bent or stretched, and then when heated the alloy.
This is only possible due to a remarkable range of smart materials. One of the materials being used is a nickel titanium shape memory alloy. It can be bent and twisted like ordinary steel wire, but when an electric current or heat is used to raise it above its threshold temperature it enters a super elastic state and returns to its original shape.
Micromanipulators and robotic actuators have been employed in order to mimic the smooth movement of human muscles (13,14).
This research studied the optimal design of shape memory alloy (sma) muscle wire bundle actuators. Current literature describes the use of multiple muscle wires placed in parallel to increase the lifting capabilities of an sma actuator, which however, is limited to wires of like-diameter.
The artificial muscles that actuate matapro-1 are shape memory alloy (sma) wires, which ensure effective grip strength for many everyday objects, without causing any noise. In order to avoid the need to cool sma wires in the small volume of the fingers, the sma wires are not routed through the finger phalanges.
A shape-memory alloy wire is an alloy that remembers its original shape and that when deformed returns to its pre-deformed shape when heated. These unique metals made from combinations of two or more elements, exhibit hardness and elasticity properties that change radically at distinct temperatures.
The shape-memory effect was discovered in a gold-cadmium alloy by arne olander in the 1930s, but practical shape-memory alloys (also called smas, muscle wires, memory metals, and smart metals) only started to become popular in the early 1960s after the development of nitinol at the us naval ordnance laboratory (nitinol actually stands for ni ckel ti tanium n aval o rdnance l aboratory).
Shape memory alloys will be used as actuators, simulating the action of the flexor muscles in the fingers, hand, and wrist.
The most widely used shape memory material is an alloy of nickel and titanium called nitinol. This particular alloy has excellent electrical and mechanical properties, long fatigue life, and high corrosion resistance. As an actuator, it is capable of achieving up to 5% strain and 50 000 psi recovery stress, resulting in ~ 1 j/g of work output.
Small bristles on legs are used for creating a difference of friction.
Muscle wires, nitinol, flexinol or -formally called- shape-memory alloys (sma) present a huge demand today because of their high power/weight ratio. That means that, when combined with cheap, light-weighted batteries available in the market, they are the best choice for mobile robotics.
Although these shape-memory alloys can be used in serious circumstances, they can still be used in a fun and educational setting such as robotics and making a robot butterfly flap its wings. Space wings uses only five centimeters of wire and flaps up to 36 times per minute.
Jun 24, 2019 furthermore, the exoskeleton developed by innophys uses mckibben-type pneumatic artificial muscles for the actuators, and because it is driven.
Also known as nitinol, nickel-titanium is a shape-memory material that releases heat to its surroundings when it is mechanically loaded in its superelastic state and absorbs heat from its surroundings when it is unloaded. This unusual property is the reason why nitinol is also referred to as a smart alloy or as muscle wire.
Smart-memory alloy is an alloy capable of returning to a specific physical shape with the proper.

The advantages of shape memory alloy (sma) artificial muscle are lightness and high energy density. The high energy density allows the actuator to make powerful motions. Meanwhile, sma wire contracts 6% of its length, which means that the required displacement cannot be achieved by a simple connection.
A shape memory alloy (sma, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that “remembers” its original, cold-forged shape: returning the pre-deformed shape by heating. This material is a lightweight, solid-state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems.
With its unique ability to contract on demand, muscle wire (or more generically, shape memory actuator wire) presents many intriguing possibilities for robotics. Actuator wire is made from an alloy called nitinol, and marketed under a number of brand names including flexinol, biometal, and muscle wires.
Q: so what is the difference between the all these terms: memory metal, shape memory alloy, nitinol, muscle wires, flexinol and biometal? are there differences.
Shape memory alloys are unique metal alloys that they contract when heated. The material does not actually contract, but, in the case of a shape memory alloy wire, expands radially much fast than longitudinally, so the overall effect is longitudinal contraction, as illustrated below.
Shape memory alloys muscles are the engine that your body uses to propel itself. Although they work differently than a car engine or an electric motor, muscles do the same thing -- they turn energy into motion. The solid-state phase change and bounce back effect (pseudo-elasticity) are used to make devices from muscle wires.
