Flexinol does not automatically return to its lengthened state when cool. With its unique ability to contract on demand, Muscle Wire or more generically, shape memory actuator wire presents many intriguing possibilities for robotics.

Showing of 1 reviews. However thicker wires will not be able to dissipate the heat quickly enough and it will be necessary to make some adjustments. What other items do customers buy after viewing this item?

Nitinol Memory Wire 12″ Length x. Proper control of the current is essential for satisfactory results. Things to Do Here Home Links. Perhaps most famously, Flexinol was used to operate a dust sensor installed on the Sojourner rover which landed on Mars as part of the Mars Pathfinder mission July 4, Other designs might call for a relatively powerful spring in the bias which will perform some of the work required.

Another muscls of this simple device worth noting is the use of leverage. When designing the mechanism care must be taken to ensure the the Flexinol is free to move along its entire flecinol of contraction. Mandala Crafts 60 40 0.

Introduction To FLEXINOL® Actuator Wire

However, when heated to activation, they return to their preset shape. The rubber band functions as an extension spring keeping tension on the Flexinol and keeping the gripper in a “normally closed” state. This stretching requires that a counter-balancing force be engineered into the project.

When cool these alloys can be bent or stretched, and then when heated the alloy returns to its original shape.

Please make sure that you are posting in the form of a question. Flexinol LT Muscle Wire These unique nickel-titanium alloy Muscle Wires actually shorten in length when electrically powered, and can lift thousands of times their own weight.

Flexinol wire has a consistent resistance per length and an optimum current as specified in the flexinol technical data.

Alexa Actionable Analytics for the Web. Since there is a layer of oxidation around the wire, you cannot solder directly to the wire itself.

Flexinol is a great addition to your robotic bag of tricks. Education How making is transforming learning. Crimping the wire is the only viable option. Subscribe to Make Magazine Today! AmazonGlobal Ship Orders Internationally. As with learning anything new, incorporating bias into your eire provides an opportunity for creative problem solving. For example, going from curling to flapping only takes a couple of curved folds to each side of the curling mechanism.

Marcelo Coelho has experimented with combining custom-set nitinol with textiles to create actuated fashions as well as responsive and soft interfaces like the Shutters Project: The thickness or gauge of the actuator wire will dictate the maximum force that can be applied.

Since these wires generally require hundreds of milliamps, I recommend getting a strong lithium-ion battery or use a wall power supply.

Muscle wire, Nitinol, Flexinol, SMAs ?

How-To: Work with Shape-Memory Alloy

Buy the flexinoo items together This item: Nitinol actuator wires are able to contract with significant force, and can be useful in many applications where a servo motor or solenoid might be considered. Thanks for your submission. Much of the remainder of this article will be concerned with addressing these challenges.

To achieve greater pull from the thinner wires, more actuators can be used. Flexinol is referenced in many books and research articles, and has been specified in a number of student and hobby-level robotics projects. Newsletter Stay inspired, keep making. Sign up for the Make: Working with the thin, tough wires can be physically difficult, and a substantial current can be required to achieve transition.

Great to have you aboard.
