I’ve heard of muscle wire that contracts in length (about %) when And whats the difference between Flexinol and Nitinol? or is this a. If you’re using SMAs for the first time, I recommend starting with Flexinol muscle wire (which is available on Robotshop, or directly from. Flexinol LT Muscle Wire These unique nickel-titanium alloy Muscle Wires actually shorten in length when electrically powered, and can lift thousands of.

When cool these alloys can be bent or stretched, and then when heated the alloy returns to its original shape. Robot Design – Flexinol and other Nitinol Muscle Wires With its unique ability to contract on demand, Muscle Wire or more generically, shape memory actuator wire presents many intriguing possibilities for robotics.

If it were the Flexinol pulling the gripper to the closed position then it would need to go to a fairly precise location and could only grasp objects of a specific size, or else risk damage to the object or the Flexinol. Flexinol does not automatically return to its lengthened state when cool.

Flexinol LT Muscle Wire: Electronic Component Wire: : Industrial & Scientific

You can add extra flaps to the folding mechanism to make a parallelogram, which makes surfaces rise off the page. Flexinol in most applications uses electricity to generate the internal heat needed for transition. When used in medical applications it will frequently be active in the range of human body temperature.

Flexinol and Muscle Wires are both trademarks of musc,e California company Dynalloy.

To be used as an actuator, Flexinol must be attached both to the mechanical elements where it will cause movement, as well as to the electric circuit that will energize it. Amazon Restaurants Food delivery from local restaurants. Great to have you aboard. Add flexnol to Cart Add both to List. By Jie Qi Jie Qi. Amazon Rapids Fun stories for kids on the go.

For example, going from curling to flapping only takes a couple of curved folds to each side of the curling mechanism. However, when heated to activation, they return to their preset shape.

How-To: Work with Shape-Memory Alloy

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.

ComiXology Thousands of Digital Comics. If a longer cycle time is acceptable, then lower current can be supplied. One of the most dramatic mechanisms is the curling mechanism where you simply sew nitinol to the paper. Perhaps the greatest challenge lies in the fact that actuator wire must be stretched back into its lengthened state with each activation cycle.

You want to give it enough for a dramatic effect, but not so much current that the wire burns out and stops contracting. Learn more about Amazon Prime. In the meantime, keep making stuff!

Fflexinol Designer Fashion Brands. Too little current and the wire will fail to contract. Note that Flexinol has fairly high resistance compared with copper wire and other common conductors. Please check your email. There was a problem filtering reviews right now. Thanks for your submission.


In some applications it is possible to activate the wire without additional resistance in the circuit. Other designs might call for a relatively powerful spring in the bias which will perform some of the work required.

Of course musclle is no free lunch.

In some applications it is possible to use the natural motion of the mechanism itself to juscle the recovery force. Newsletter to keep you inspired with new projects and more product reviews. There are many potential approaches. If above there were 2 inches of wire rather than 5, that same 3 volts would deliver 1. See and discover other items: East Dane Designer Men’s Fashion. Start with a low duty cycle and work your way up until you get a strong enough movement.


Some designs might call for vlexinol bias as close to the required refresh force as possible to provide as much work energy as possible from the actuator. Consider the very simple robotic gripper illustrated nearby.

Working with the thin, tough wires can be physically difficult, and a substantial current can be required to achieve transition. Please check your email to confirm.

A force flexibol be applied to the wire to pull it back to length.
