Artificial Muscle Fibres

Scientific animation produced by Magipics for the Intelligent Polymer Research Institute at Wollongong University.
The animation describes in a stylized manner how a nanofibre becomes super-coiled when twisted. This produces a fibre of exceptional strength which, under electric stimulation, can contract and lift heavy weights. This has a great potential for use in prosthetics/artificial limbs, robotics and "exoskeleton" devices.

I like that this one functions with electricity instead of being Pneumatic,like many others , seems way less likely to fail and easier to fix as opposed to an high pressure pmeumatic one , plus being less noisy since it doesn't needs a big and loud air compressor

On the contrary, working on air ( pneumatic ) or hydraulics is better than the need for electricity and batteries. Pneumatics do not require equipment that produces noise to operate. The compressor is often small at this level and can be isolated to reduce noise. It also does not require electricity to operate, but there are multiple sources of energy depending on the engine. Electricity generates a lot of heat and electromagnetic pollution, and the device is weaker and more likely to fail, so a self healing liquid is often used! In my opinion, we must diversify our energy sources and not rely only on electricity for everything small and large to operate appliances. This provides a much wider and more efficient range as it is off the grid ! Note: It is widely known that electrical appliances and the programming that accompanies them are usually difficult to maintain and therefore require a specialist. Even Tesla cars, for example but not limited to them, are only maintained at the Tesla factory !!

Thanks!

Nitinol coils to cause contraction with heat. Hella inefficient, 'cause it's based on heat

[@hebertfogos2020]

I was think about something similar! Is a great ideia! Let's see if this way of artificial muscles be really the most interesting and efficient!

[@williamtarabalka4920]

More research please.

[@14supersonic]

What kind of fibres would you use that can conduct electricity and contract when a current is applied? I've tried Nylon for undergoing the super-coiling process. It's very strength is a great quality, but Nylon isn't very good at conducting electricity from what I know. Any ideas?

[@magipics]

That is not my area of expertise. I just created the animation. You will have to contact the client: The Intelligent Polymer Research Institute at Wollongong University.

[@NecroAngelDeclaresWar]

Mix it with graphite or metal particles

[@theowild2524]

conductive nylon sewing thread for wearable electronics works really well. you can use a length of thread and of fishing line in the same coil for increased strength

[@kidnamedgrass]

The copper wire is twisted along with the fibre actually

Nitinol

[@PopBoomPop]

I really love this video

[@magipics]

Thank you!

[@Tenebrousable]

Very good. The power is provided by the signal to contract, as opposed to muscles own stored chemical power, that the nerve signals to use, seems to be the inherent difference. The power source is centralized outside the muscle itself. The 'fuel' is stored in the brain, instead of the muscle itself, right? But, it seems it makes it slower and use more space. Is this an egnineering challenge forseeable to overcome? Or inherently more inefficient approach, would be my worry.

[@rohncarver3585]

wonder how it would handle in 50*f to -20*f and then there is weather 80*f to 123*f how would these handle the temperature difference

Where's the sound? I don't understand how it works if you don't explain it.

[@magipics]

The client just wanted a silent animation, they did their own narration live. Have a chat to The ARC Centre for Electromaterials Science if you want a more detailed explanation!

[@bjl1000]

So you heat these to make them pull?

[@magipics]

Yes, a conducting coil generates the heat

[@fabianh.5848]

@@magipics Is heating not very slow?

[@magipics]

@@fabianh.5848 The speed in the animation is set so it is clear what is happening.

What is the yellow part?

The fabric

[@bengagliano7415]

wool usually, but it can be a interweave of silverplated polyester, cotton, wool

[@jackwhitestripe7342]

sir, is this technology available in India?

[@magipics]

You will have to enquire with the IPRI at Wollongong University.

amazing!!! magnetism....coil for muscles.....gish...with A.I. on the rise....Darpa robots will be humanoid

[@viveksidar8255]

Please Replace My arms muscles so that i can satisfy my Boss.

[@Torbjorn-ph7rt]

Very low efficiency, very small stroke, very low switching speed, and you still have to somehow remove heat. Now this is a dead-end direction. Much more interesting is the artificial muscles based on the piezo effect.

[@magipics]

Thank you for your comment. I suggest you raise your concern with the client, Wollongong University.

[@magipics]

I just created the animation as per the client's directives. Have a chat to The ARC Centre for Electromaterials Science if you want a more detailed explanation!

That's not really a muscle it's a plastic coil

[@magipics]

Absolutely- it is artificial! Just showing the working principle as per client's specifications.

[@anteconfig5391]

if the word "muscle" is a problem then you could make pretend he said actuator.

[@thatone2297]

Yes that’s true, it’s not actually a muscle, however the “plastic coil” functions in exactly the same manner real muscle fibres do and since real muscle is just made of chemicals and so is plastic you could say that they are one of the same but one is biological and the other an advanced imitation.

[@haruruben]

you would combine a series of these as "muscle fibers" to create an artificial muscle that can be actuated with electric current. There's a lot of benefits to this over motors like it's cheap, simple, and QUIET. Go look at the amount of noise those Boston Dynamics robots make... good luk bringing the Big Dog with you on a patrol...

[@Qeswara]

Pneumatic better than electricity, pneumatic can powered and controlled by anything but electricity limited by battery and semiconductors

[@dennyfpv1996]

Pneumatics also need electricity

[@Qeswara]

not necessarily!.@@dennyfpv1996
