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.

Additionally, because the activation wirf is heat rather than magnetism, these solutions do not introduce magnetic noise to a circuit – they are in essence solid state devices.

To achieve greater pull from the thinner wires, more actuators can be used.

How-To: Work with Shape-Memory Alloy

Amazon Inspire Digital Educational Resources. You want to give it enough for a dramatic effect, but not so much current that the wire burns out and stops contracting. Part of the solution rests upon how fast the response from the wire is required to be. You will also be receiving the weekly Make: Buy the selected items together This item: Newsletter to keep you inspired with new projects and more product reviews.

Muscle Wires Project Book Of course there is no free lunch. It is reliable and simple enough to hook up to a circuit. However, it is equally valid to use a lever to do the opposite and enable a large force moving over a short distance to create a small force moving over a large distance.


Working with the thin, tough wires can be physically difficult, and a substantial current can be required to achieve transition. Since these wires generally require hundreds of milliamps, I recommend getting a strong lithium-ion battery or use a wall power supply. What you will get in this package is a muuscle piece of wire which will contract slightly under the right conditions. This mechanism uses the wire as a muscle to pull the flap. Turn on 1-Click ordering for this browser. If you have an Arduino, you can hook up the wire using a transistor and PWM the power.

The ideal bias value will of course depend on the application. How it works Pressing the switch lets power fl. Flexinol LT Muscle Wire 1m.

Introduction To FLEXINOL® Actuator Wire

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. Success can be determined experimentally. Sign up for the Make: Gauge also dictates the wire’s resistance to electric current, the available current required to reach transition, and the time the wire will require mjscle heat and cool.


That same summer, I got an internship in Brooklyn building sculptures out of bottles for Aurora Robsonthrough which I fell in love with art again. Don’t see what you’re looking for? As with learning anything new, incorporating tlexinol into your designs provides an opportunity for creative problem solving. Share Facebook Twitter Pinterest.

Muscle wire, Nitinol, Flexinol, SMAs ?

Flexinol in most applications uses electricity to generate the internal heat needed for transition. Flexinol is referenced in many books wirw research articles, and has been specified in a number of student and hobby-level robotics projects.

Write a customer review. In this case, when the wire contracts, the paper must curl around it to make up for the shorter length of wire. Get to Know Us. Please check your email.

There was a problem completing your request. Hobbizine for all the things you do The hardest part about using muscle wire is muwcle the amount of current running through the wire. This strong and refined steel wire is inexpensive and can be bought in many gauges from hobby suppliers. Welcome to the Make: Great to have you aboard.
