- Researchers at EPFL LMTS and Politecnico di Bari have developed thin, flexible pumps in the form of fibers. In essence, tubing that generates its own pressure and flowrate. This allows high pressure fluidic circuits to be sewn directly into textiles and clothing without the need for an external pump. In the future, these pumps could be used to power artificial muscles for soft supportive exosuits, or for wearable heat management systems.
The work was published in Science in March 2023.

I don't have access to the full article, but the summary over on Science says the fluid needs to be dielectric. Pure water is a dielectric, but dissolved impurities can make it somewhat conductive. How pure does the water have to be for this device to work well?
Idk probs 98 pure.. i mean you can pic up distilled water from the store or make it yourself pretty easy with the right set up
Don't forget that distilled water will leech ions from the tubing and become conductive if not continually cleaned.
Probably better to use oil like in high voltage transformes.
@@g_glop My thought too, but viscosity could be an issue with the diameter of the tube being used.
@@custos3249 oil also has lower thermal mass so you'd need to pump a lot more of it
@@g_glop Yep, and since the point is to use it as a coolant, it'd likely be wildly inefficient. Even as is, it likely pails in comparison to a simple peristaltic pump. Neat idea though.
Imagine a species that evolved self-pumping veins instead of hearts.
whta is a heart but a self pumping vein.....
@@bottlekruiser A centralized muscle with valves, chambers, and a shape that is not a tube... not a decentralized network of tubes that can contract down their entire length, has no valves, chambers, and is definitly NOT heart shaped...
You need a creature that can generate and also control energy though there are creatures here with self pumping veins (like jellyfish) however the function of it is very slow compared to a human heart that needs more flow when exercising or less when resting.
I think for larger individuals affected by gravity, a heart pump works better as it uses less overall energy to function.
However if gravity is less concerning, perhaps you can have a creature that doesn't need a singular pump and survives on electricity(wiring) as the vein structure. Perhaps the AI field can help create it.
@@tjpprojects7192 heart's shape is a few short and thicc tubes stuck together, with a couple constrictions here and there for better peristaltic action. valves are the logical limit of such constrictions, and chambers are just tubes between them. a strong enough peristaltic tube is *all* valve.
If you look at the heart of a primitive chordate like a tunicate, it is literally just a muscular section of vein that pumps blood. A fish heart is not much more complicated than that, and it's not until amphibians and reptiles that you start to have real chambers. The four chambered mammalian heart evolved very slowly from literally a self pumping blood vessel.
Active cooling is the most important thing in clothing EVER. They have gotten heaters but coolers are way more important
@@SanityTV_Last_Sane_Man_Alive it's easier to make something warmer, but once you already strip naked, it's harder to make clothes that cool you down more than that.
Also, there's a lot less temperature available to go down, vs how much higher it can go up. You can be at +1000C but -1000C literally doesn't exist.
@@SanityTV_Last_Sane_Man_Alive When the ambient temperature rises significantly, the body relies on mechanisms like sweating and increased blood circulation to dissipate heat and maintain a stable internal temperature.
Individuals might withstand temperatures of around 120-130 degrees Fahrenheit for a limited time, such as in a sauna or hot tub.
However, prolonged exposure to such extreme temperatures can lead to heat-related illnesses like heat exhaustion or heatstroke and death.
@@SanityTV_Last_Sane_Man_Alive Right. Heat stroke doesn't exist.
Oh help we are all gonna dye because of climate change ;-)
@@onnonius It's not that we are all going to die from it, but there will be massive population displacements, civil unrest, more intense storms, more intense drought/famine...
Or do you think you've outsmarted all the climate scientists?
It doesn't doesn't show a big part: the power source. It says "high voltage", isn't that dangerous for a wearable?
Voltage says nothing without the Amperes. E.g. 100v x 0.001A= 0,1W, you could not feel it!
High voltage is only dangerous if handled in an unsafe way, if all the proper insulation is there then it is fine.
@@conorstewart2214well but accidents happen and you cant just wear large voltages with lots of current lol I think you dont really need is much power so it wouldn't be too dangerous anyway
I have checked the links you can find some graphs with all the info you ask, but there are al lot of configurations and power settings for example: at 8kv/mm with 2mm diameter it can use ~12 w/kg for 800mm lenght
In theory everything wearable is dangerous. It’s all about application and who’s applying it
Since you have high voltage in contact with water, do you have any issues with electrolysis occurring?
Afais there is no direct contact with a liquid
@@weberito There is contact. Look on YT for "how to make a fiber pump". Since there is contact there will also be erosion of the wires .. both chemical and charge induced
@@xenunoYou answered the question I was having: Why are they selling this as being for clothes? Maybe long-lasting is difficult and clothes get worn out anyways?
@@0ooTheMAXXoo0 Toxic maybe if all weather. For lower temperature freezing protection, salt solutions would corrode the wires and antifreeze (ethylene glycol) can be poisonous. This video is more a proof of concept than any pros-cons analysis
The fluid doesn't have to be water.
this is AWESOME!
What voltage/current is used to power these "pumps"?
It's probably using a battery or a wall outlet.
(Sorry, I'm just trying to be on the same level as the rest of the group... lol)
High voltage but I guess low current. Actuators with similar electrostatic principles work around 10kv to 15kv or more. But with low current is just as bad as a shok you get from rubbing your feet on the carpet. (You may already know that but I put it here so no one comes shouting about the "dangers" of high voltage)
Mind blowing ❤
Impressive !!!
Is it strong enough so you don't need to do the winding everywhere ? Can you use a 10 cm long "pump" and attach it to normal tubing ? Like what pressure does it produce ?
Each meter of pump generates 1 atmosphere of pressure (100 kPa), and flowrates exceeding 50 ml/min are also possible.
Great idea
Yea, we always need music with tension in it to accompany a tech item.
I turned off sound.
Superb!!!!!
I need one of these for when i wake up
conventional pump system can be miniature in scales but there are lobies do not want that, because Their consumer interests Compatible with complex electrical and consumer electronics. that my opinion, It is nice for someone to try to miniaturize the hydraulic system from pumps, hydraulic motors, and valves so that we have another independent control system in itself that does not require electricity or complex electronics.
Well i guess the main application is heat transfer, because it can only use dielectric liquids such as mineral oil. However since the tubes are so small they dont move a lot of volume, and i doubt they would do a very good job at moving heat.
Maybe attractive for scooter engines
Pure water is also dielectric though. I could imagine someone using this to cool a VR headset
so what happens if the wire breaks somewhere along the tube... then entire length of the pump dies. Physical pumps my be rigid... bu they can also be made very small and made to run on very low voltage... high voltage circuitry surrounding the body is very bad for other sensitive electronics.
This is brilliant
I am more interested in its efficiency compared to a regular pump. Does anybody have some Info?
Probably only good for small stuff like this fr. Using the whole magneto deal on larger volumes of what requires so much power and isn't efficient at all
Yet one more step closer to my idea of hydraulic carbon nanotube muscles :D
"Your idea" 😂
Looks great but efficiency is really bad. They write that they use about 0.9 Watt and reach a flow rate of 55ml/min... a simple small fluid pump uses about the same energy but puts about 30times the flow rate. So the efficiency of this "fiber pump" is about 30 times worse than a regular, cheap pump... and this ignores the fact that the fiber pump needs a power source that delivers several kilo volts, such a power supply will lose additional efficiency, while the mentioned regular pump works directly with the voltage of regular batteries.
Is there an application for this in biomedical field?
This is very interesting, I wonder what other applications fluidics could have in the future.
Considering it's high voltage, is touching water, is most likely profusely expensive to produce, requires costly distilled water to run and also being pretty niché, not many.
fluidics technology needs to be freed from electricity and electronics, in fact it is nice to see a system that does not need electricity and does not have electronics. If they could, for example, create a fluid control system that does not depend on electricity and electronics, this would be very futuristic.
It would be amazing if it weren't for electricity and complicated consumer electronics.
Are all of these from idependent resources ? Or of any institute?
How do I order some of that tubing?
che figata!
Ok, boss, we've made the video, now all we need is some inane music.
"Mom!! You forgot to charge my pants!!" 💀
Isn't need more energy for ionizing fluid?
That music is your typical eletronic keyboard futuristic music using a few simple notes, popular in in the 80s and 90s. Gives me a laugh everytime I hear it.
Hi there, I am a student majoring in interactive design, and I am focus on one project about microfluidic and liquid pump. This video really inspires us, so I am wandering whether this fiber pump could be bought in some online shopping apps or can only be made in lab. Looking forward to your reply.
@@micahpacileo2307 No shot lmao, TEMU sucks.
Cool
can this device reversed for generating electricity through water flow?
because i think the principle is like triboelectric nanogenerator
I don't think so. They are ionizing the water using high voltage. Once ionized, the water will respond to a magnetic field. Ionizing water would require quite a bit of energy, so probably you would consume more energy than you could capture.
it may. there are other expirements that i've seen where water is dropped through two opposing rings connected to two circuts. and it generates enough voltage to cause a spark to jump a gap. the name of the device slips my mind right now.
Great, more parts for the Terminator Robots.
This will be very useful in the future, for making cooled clothing, that will be necessary once the outside temperatures become intolerable... at least for those that can afford them.
If outside temperatures become unbearable to the point that you need a portable air conditioner not being able to afford it is the least of your problems.
@@hiiamnick1992Sarcasm, my friend... hard to translate into a comment.
I just wonder if our pods will be air conditioned.
@@GeneralChangOfDanang Build underground... it's nice and cool down here.
One step closer to myomer and battlemechs.
100% Silent Liquid Cooling for CPU\GPU\Everything? Cheaper and more efficient than heat pipes?
The system in the video is energy hogging and very inefficient. The CPU itself consumes a lot of power, so let alone adding the one in the video to it !
Now that is freakin cool. Imagine the cooling systems that would be possible with this stuff, now! No physical pump to wear out and die. Just an A/C to D/C converter and a coil pack.
Cooling systems with this flowrate wont be very effective
@@engineer0239 Not for vehicles, nah. But I’m talking about heat sinks for computer equipment, small electric motors, and appliances. These tubes are also a really new technology. There will probably be further ways to optimize the designs to get more flow rate, or make the tubes themselves larger.
It corrodes and dies quickly and is inefficient. A physical pump will have a much longer lifespan and a much higher efficiency than the one in the video.
I wonder if it can pump blood or not
Amazing, why has this no comments?
Thanks for being the first one!
Would be great for space suits.
downside being very inefficient , tho I guess in a closed loop system at least usable
Interesting. And it's bound to have several practical applications.
Finally. I can own a Mecha.
This must be in the next dune movie NOW!!!!!!!!!!!!!!!!
Then use that electro-hydro tube pumps for the hydraulic artificial muscle actuator.
i can certainly see this being useful in cosplay as well as electronics along with other fields
Your first idea to apply new technology is to incoporate it into _cosplay_
Jesus. What a waste.
@@dillis2188 Cosplay can inspire kids to pursue engineering careers. Dismissing ideas without putting a bit of effort thinking is an actual waste
Can this be used as a blood pump?
No.
so instead of a bulky pump I am now wearing bulky high voltage generator and risk getting shocked?
No, because the high voltage generator is not as bulky or as heavy as a pump that also needs electronics anyways but it is also well insulated and the circuit can have protections that sense human contact 200 times per second if you want. Everything you pointed out was already solved decades ago 🥱
Clicked for the LEGO guy, stayed for the amazing science 🤩
Thanks ;)
Thats what Im taking about, Now imagine that will nano hydraulic tubing,I told you tis 4 years ago super strong
good going ,you should get a award or something
You forgot veins for humanoid robots
Mechwarriors your cooling vests are coming.
Spoiler: you have to apply a current to power the process.
Why would it work without energy?
If this is real, to me this is groundbreaking 😮🤯
For Robotics
That thing is just gonna eat power tho
now make it 1000 times smaller
Haha, right, my earphones that die after 1-2 months of use from flexing would like a word
STILL SUITS
What about degradation of electrodes? This is principle known for a long time
oh god the clowns are evolving. now they'll be able to spray people even without flowers
🤨No pumping is happening without an energy source.
What did you expect? Free energy?
@@Ezio-Auditore94 : Of course not, that was my point.😂 Silly.
@@______IV You thought they claimed free energy? You're even worst than I thought 🤣
@@Ezio-Auditore94 : The video shows water being pumped without a power source. So either they went to great lengths to hide the power source which is the purview of free energy hacks, or they’re implying the tube can pump without an energy source which is implying that perpetual energy is real.
@@______IV And you thought they claimed free energy because the focus of the video is the new tech of fiber pumps instead of the decades old electronics? Then every car commercial where they don't show the gasoline being poured in the tank leads you to assume it's claiming free energy? Or that they claim cars grow from trees because they didn't show how they manufactured the car? Are you incapable of understanding implied facts? They even show you the copper wires, what else do you expect? They also have to explain to you they filmed the video with a camera or you can't even deduce that? That's some kind of autism yk
That music was distracting
Water cooled clothes is the big thing that will change fashion
These are not self pumping at all. They need a power source to cause movement, just like any other pump. Piezo effects are not new.
Clearly by “self-pumping” they meant that it is itself the pump, rather than requiring a separate pump. Obviously they didn’t mean that it was violating conservation of energy?
Ah cool another thing that never gets used in anything
capilar effect
It's not the "fiber" that's important, it's the electricity, which moves the water, which produces heat, and the magnetic field that creates the contraction. Fiber is flexible.
I don't think it's physical force or thermal force. I think it's magnetic force itself that propels the water through the tube.
@@benargeeit's the electrostatic force applied with an alternating field on a polarized fluid.
Who will want high-voltage wires wrapped around their biology - not me, thanks.
explains everything except the very basic functioning principle
One step closer to making my mjölnir suit.
These will also be used for fuel lines...... Yes, I'm kiding, don't do that....
Sounds like some black project declassified shenanigans.
Mmmm water and high voltage in my clothes!! Succccccchhhh a good idea.
If it works with blood this could replace or augment failing hearts one day.
A river doesn't pump water and neither does this. Water moving does not equal pumping.
Flow rates? Pressures? Efficiency?
What you show is a pump managing several mL per minute, so it can't flow well. That pump has ~1cm lift, so it can't build pressure. Then you show it running for several seconds…before it started melting…
Tell me you made a great leap in technology for the sake of vanity without telling me.
looking at the thumbnail, what if the petri dish walls were 20 feet tall and it still had the little hose and you used the water pressure to get flow back up to the top where a waterwheel was turned to create electricity. The water would fall back into the same container keeping all that volume and pressure. Scale it up 50x. Would that not work? I'm no engineer, obviously
This is great, but... High voltage wires embedded in clothing? Oh boy... someone has a death wish... or at least some masochistic trates...
INOVATIONNNN
Can you replace my veins with this so I never have to worry about heart failure.
i love hwo you just rip and tear old 3D printer to make mashine for creating those tumes XD
tbh i think this is a not so great idea, first off, high voltage, secondly, you have to keep the water really really clean, and last but not least, this has been around for ages! submarines/ships used this as silent engines (well, really similar to that)
Another miracle that nobody will ever see.Yawn...
Brilliant concept....most annoying music ever.
Yet another in a long line of "Duh! Why didn't *I* think of that and make a million dollars?!?" ideas... :)
This is a multimillion $£€ idea for F1 racing suits.
Thermal regulated body armor.
NOT high pressure
All fine and dandy until competing corporations developing the technology spark the Tube Wars of 2057 over a tube patent.
self-pumping? very misleading.
"Still Suits" there almost real.!!!
literally laughed when I saw "Future" in the title. This trick is literally the oldest in the book (Faraday) when it comes to understanding electricity. Good laugh, but credibility went out the window.
Literally placing active electric wires inside of water pipes is the future? That sounds a bit dystopian.
horrendous repetitive tune
Why is this not a perpetual motion device? How is it not connected to tiny water wheels? I smell bs somewhere in this.
Annoying music.
