Encapsulating Conductive Polymer Actuators-Part I
มุมมอง 13K10 ปีที่แล้ว
Professor Geoffrey Spinks (University of Wollongong) demonstrates an easy method to encapsulate a conductive polymer actuator. Polymer actuators may contain an electrolyte which will leach out when submerged in water, hence reducing the life time of the actuators. Here, Prof. Spinks uses a simple nail polish to keep water away from the actuator. Other materials such as rubbers can also be used.

7:11 did he say professor robotnik?
potential to be huge industry- very clever.
You mention that it could be used for artificial muscles. Do you have any demonstration of this?
But its work or just dont?
The hard part was done, testing was not done at the end. This is like climbing a mountain and when you reach the water fountain you don't drink :)
Hhha he should go on the other end
What forces can that single strand produce?
Have you actually bundled them into something similar to a total human muscle and if so how did it go?
Hello sir : What is the name of the solution used? at 1:40
sir it is very good for india
Why an erotic background music
Seems to be a lack of labcoats in good old Wollongong
The yarn you use is no longer available, which product do you use now as a replacement?
For the specimen that was constructed in the video, how much force/work is the specimen shown able to do, per strand? (Newtons? Sry , I'm not any sort of expert, just curious) I'm assuming that they would function in bundles as would our own muscle fibres to do useful amounts of work? Thanks for the video.
come on, give the girl a good fitting lab coat.
Me estresa la bata que le queda grande
Necro comment, but how much would you say that one fiber of this can lift compared to a equivalent sized human muscle fiber?
I got a idea make a air muscles but instead of useing air compressing maybe try electric magnetic slime in a tube not sure if it will work but it be cool to try
I am sorry, but What does this glove do extraordinary with lymph?. Thank you.

really cool, love it
*Perfect and I’ve used it for ballon arches as **enjoyable.fishing** recommend well as other decor with parties. It is strong and will hold up well. It works so good that another decorator stole my roll at an event!*
I think that these are so interesting and this concept is awesome. I'm really curious as to how long these would last though. I mean say we built a arm will it keep working the same after thousands of contractions?
This video is amazing
Good thing she’s wearing so much protective equipment to protect her from that thread
I mean that is just typical lab procedure but heat treatment would also make the metal coil inside fairly hot also
Has this job been published?
No - this is unpublished work.
Nice
Nice
That's nice. But I wonder how thick the silver-coated nylon was and how long was it used.
The silver coated nylon yarn we used here was around 0.2 mm in diameter and we have used the coiled muscles made from these yarns for many thousands of cycles without any problems.
@@BionicMuscles Thank you for the reply. I appreciate it.
I'm sorry but I have an another question. I tried making artificial muscles at home. The length of the nylon was 1m and the thickness was 0.2mm. And I made a 20cm coil out of nylon. The coil was then heated to 180 °C in an oven for 1 hour. Those coils boasted significant shrinkage. We also compared the calculated and actual values using the linear equilibrium coefficient of nylon. However, the calculated value was much smaller than the actual value. so, can you explain the physical principle behind the coil?
@@SinWonMiSang The coils shrink in length because heating causes the fibre that makes up the coil to untwist. When this happens the length of the coil reduces. This is the same phenomenon that occurs during the stretching of a coiled wire spring: the wire actually twists as the spring is stretched. You can see the fibre untwist on heating by making a sample from fishing line and twisting it until just before coiling. If you then heat-set this twisted fibre you will trap in the twist. Next, if you heat and cool this fibre you will see it untwist on heating and re-twist on cooling.
Beaker needs a smaller lab coat.
I'm pushing your idea to Tesla. Soft robots are the future.
Tesla knows all about it, as does everyone else in the industry: th-cam.com/video/9XLw_cNwV88/w-d-xo.html
They don’t have money to give this scientist a proper sized clothing!!!
Hi BionicMuscles and Dr Spinks, do you have any videos showing the usage and operation of these electrically stimulated fibres and details on electrics, operational time... I would be really interested to use this for an art piece I'm working on
Hi Joe- operating these muscles is really simple. Just supply DC electrical power from a battery or similar. The more volts you put in the faster the muscle will contract. Cooling occurs when the power is turned off, although it can be slow. We typically use around 10V to heat up a muscle that is around 6cm in length and it contracts in 10 seconds or so. Note that they will get very hot- up to 150 degrees Celcius or more if you leave the power on. You can play around with different voltages to suit your needs. Best of luck with your project.
@@BionicMuscles oh too bad it’s so slow. For robots you need it to contract and relax in tenths of a second. Any way to make it snappier?.
@@k1ng401 We have made really thin fibres into coils by teasing out individual filaments from multifilament polyester yarns and then twisting and coiling them. They do contract and expand very rapidly but you would need many thousands operating together to generate high forces
@@BionicMuscles do you use a correspondingly thinner conductive thread when you do that or have you contined to use the same silver coated nylon you used here?
Is there other places that I can but the silver-plated nylon
We are not aware of any other suppliers for the silver coated nylon yarn. However, as an alternative approach we know that others have had success by first making coils from ordinary fishing line and then over-wrapping the coiled fishing line with a thin copper wire. Its best to wrap the copper wire in the opposite direction to the coil.
All I could think about was how big her lab coat was. Crazy. You are showing something as important as this and you take our attention away because of an oversized coat!!!
now whose fault is it for being distracted by a mere coat.
Maybe you have Attention Deficit Disorder? While I noticed the lab coat was a bit large, it in no way distracted me from the information what was being put forth. Regardless, if her lab coat distracted you to the point that you were unable to pay attention to the video, you should consider seeing a doctor. There are some who simply cannot learn in a classroom because they can only focus on the teacher/professor's hair, clothes, speaking style, etc., despite none of it being relevant to the course material. I can only imagine how difficult life must be for people with these types of focus issues. I know there are medications that can help though, so do consider seeing your doctor. Best regards.
Does this contract and lift as much as human muscle fibres do? Is it even possible that the artificial muscles could outperform human muscles in terms of both contraction length and lifting ability
Just wondering but arnt muscles usually interlaced? Like I’m not that much into understanding mechanics or anatomy or science but the diagrams I’ve seen of like arms usually there is many muscles so from what I’m picking up, arnt these artificial muscles kind of impressive? Like a few centimeters, Isant that more then ours move ? Again this is all going over my head .
you sir... are a genius
@@wiredvibe1678 a year later, wow this actually sounds smart. Was I actually understanding diagrams? Wild I don’t remember making this comment
@@awlomthesheepermen you are right. I have seen some other videos where people have tried twisting the actuators. And various other things to improve the strain... but honestly these things have massive range of movement compared to our muscles. Also, I haven't found anyone trying to abstract how our system of muscles work to move our limbs. Either they seem to be trying to recreate it 1:1 or not at all. Anyways I'm excited to see what I can build with these actuators!
@@wiredvibe1678 hey I just like learning about stuff, but hey maybe if you are building stuff you should try making a video talking about what you’re trying to build and your idea and process, it would be a very fascinating
@@wiredvibe1678 anyways yeah this whole field is so cool, I hope you make something cool. I’m not in engineering, I just do dishes at a restaurant
Very helpful video, thank you so much! What's the maximum contraction we can expect and how predictable is it?
The maximum contraction depends on the coil geometry and can be as high as 80% for large diameter coils. If you can access the figures of the original report (DOI: 10.1126/science.1246906) then you'll see from Fig. 2 that the contraction is set by the coiling conditions and the contraction is quite stable for a range of applied loads above a certain threshold.
How much voltage and ampere do you need to let it contract?
We generally apply around 1 W of electrical power per 5 cm length of muscle. This heats (and contracts) the muscle in a few seconds. The actual voltage applied depends on the sample length, but we typically use around 0.5 - 1 V per 1 cm length of muscle.

Could be misused to capture bikini shots of unsuspecting people who identify as women
For that to happen it must be used by someone thinking like you :)
It's called a lay. The twist in fiber or rope is the lay.
Very much enjoyed this, but would have been nice to see it actually work
Man has twisted fibers for thousands of years, so fun to see how extraordinary this concept really is.
I wanna make a fridge using this concept. The cooling and heating effect i find interesting. Could also be used to vaporize and condensate water for collection of distilled water. Which later could be filtrated for purified drinking water.
