How-To: Work with Shape-Memory Alloy

For example, in the case of an arm that lifts a dead weight, when power is removed and the Flexinol cools, the weight flexihol the payload will stretch the wire back to its extended length.

Too little current and the wire will fail to contract. Home Links Privacy Policy.

Please try again later. At the atomic level, the crystalline structure of an SMA changes with heat from one regular structure to another. If you have an Arduino, you can hook up the wire using a transistor and PWM the power.


Please make sure that you are posting in the form of a question. B00BY4 Item model number: There are many potential fkexinol. Roger Gilbertson, author of the Muscle Wires Project Book, recommends the N-scale rail joiners which are used to connect model railroad conductive track. It uses Flexinol and a rubber band around a pivot. Amazon Second Chance Pass it on, trade it in, give it a second life.

Flexinol LT Muscle Wire. A force must be applied to the wire to pull it back to length. So I changed my major to mechanical engineering because they get access to the machine shop! Image Unavailable Image not available for Color: Would you like to tell us about a lower price?

Share Facebook Twitter Pinterest. His writings on these on other diverse topics appear glexinol here and across the Internet. Hobbizine for all the things you do If you see a jerking motion, chances are the wire has gotten too much power and might in fact have burned out. When cool these alloys can be bent or stretched, and then when heated the alloy returns to its original shape.

The potential advantages to working with Nitinol actuators are significant. Add both to Cart Add both to List. In most cases it is necessary to engineer a biasing force into the mechanism. When designing the mechanism care must be taken to ensure the the Flexinol is free to move along its entire range of contraction.

The most commonly used SMA is nitinol nickel titanium. Success can be determined experimentally.


How-To: Work with Shape-Memory Alloy | Make:

Likewise, a robot leg that lifts the machine itself can use the weight of the robot to refresh the Flexinol. A spring in this context mscle any elastic device that will regain its original shape after being compressed or extended. Usually ships within 2 to 3 days. Share your thoughts with other customers. A couple of convenient and readily accessible sources of springs for experimentation include rubber bands and the compression springs found in retractable ball point pens.

Newsletter to keep you inspired with new projects and more product reviews. You want to give it enough for a dramatic effect, but not so much current that the wire burns out and stops contracting.

Introduction To FLEXINOL® Actuator Wire

Flexinol is referenced in many books and research articles, and has been specified in a number of student and hobby-level robotics projects. To make a self-folding flap, anchor the ends of wire on muacle main side of the crease and attach the center of the wire very close to the crease on the flap. However, most bias solutions will involve a spring of one sort or another.
