I’m an orthodontist…we also use this to align your teeth with braces. The wire comes in a “standard” arch shape (the shape of straight teeth around an arch, it’s a U shape). The wire deforms when we put it in the brackets which are on mis-aligned teeth (aka not in a perfect U shape), and the wire slowly returns to its original perfect U shape, helped by the heat of your mouth, which causes your teeth to move to their ideal position (which happens by your teeth causing your jawbone to dissolve and reform). It revolutionized orthodontics. Awesome material for sure!

Allright I want to use this with my 3D printer. I wonder who will be the first to create Notinol as a filament. I'm handicapped and would love to use it to help me walk longer distances. Right now I can only walk about 30 feet (10 meters) before I have to sit down for a minute and rest my leg. God bless the scientist who discovered this amazing metal.

Years ago when worked in medical devices we used it as a framewlrk for vascular stents and grafts. Realy cool material.

I remember seeing videos on ufo documentaries that showed a piece of metal that could be folded and would go back to its original Shape. I bet it was made of nitinol and the filmer was just blowing hot air on it off camera.

I have this inside my veins. I have a rare condition in which my iliac artery compressed my iliac vein due to my anatomy and caused a blood clot. My Interventional cardiologist put this inside my vein so that my iliac vein won’t collapse again. It literally saved my life.

Wasn't this kind of material mentioned after the Roswell crash?

This metal will never forget

I'm an optician and I'd never do the wild bending like the lady. I've seen my share of broken nitinol frames 😆 Great video though, a lot of informations I didn't know.

my brain is not enough to understand all these stuff!!! its really a magical one and I am thankful to all the scientists who are working on this. God bless you all ❤❤. love and respect 🙏🏻

Every man in a cold pool could relate to that spring

Metal that remembers: Instant Nostalgia hits!!!

Ah yes. The old heat gun to the foot shoe. What an awesome idea.

"The Metal That Remember" kind of awesome scifi movie title

You could use this as an alt to traditional fiberglass casts and those big bulky boots they give you when you break bones. 3d scan the persons arm, then 3d print the cast out of a stiff but comfy material and then line it with Nitinol so everything is reenforced

2:48 - I have glasses made of the same stuff. Go ahead, keep bending them around 90 degrees or more. It stresses the metal and at some point it WILL break, despite the otherwise amazing properties.

Sounds similar to the meta-material, or “memory metal” supposedly found at the Roswell incident in July 1947. Reverse engineered?

Great video about the practical applications You guys are really engeneerers! 👏👏👏👏 I will certainly look for more information about that metal in itself!

Not that it matters, but the first time I purchased Nitinol was in the late 1980's. It was through an educators science source catalog, so I'm not sure if that classifies it as being available to the general public? 🤔 Cool stuff!

Jacque Fresco talked about materials with memory 20-30 years ago

Kinda like when the military uses similar technology on their aircraft, one it reaches certain altitude, the heat changes the form of the craft, allowing it to go much faster

Wow!One of the awesome metal on earth.

Shape memory of metals or alloys are common thing but some alloys exhibit this property more to small variable temperatures. Applications are much more vast and start from using in human hearts to Space shuttle and sensors.

Straight from the Roswell UFO crash. Thanks to Phillip Corso.

Amazing Content

Metal can actually hold memories better than most materials and very few can see the past memories of that object by holding it.

This is great. Amazing Metal! Thank you for sharing!

Thumbnail: "WOW! HOW DOES A METAL HAVE SHAPE *MEMORY?*" Video: "Nitinol! Chance! Heat! Industry! Sound! Names! Magic!" Netizen: "Where's the science? When's the question going to be address-... it ended."

I heard of this in the Roswell crash

I find it very interesting that the naval centre were doing research with Wright Patterson air force base as the time of this so called chance discovery.

Been used in fishing lures for 20 years. Was in the space industry before that.

Learned something usefull Thank You

Can you highlight the cost associated with that? And what about places with sub-zero temperature

US: make a missile capable of orbit re-entry William: k imma make sick sunglasses 😎

So we’re finally seeing the benefit of Roswell

Ok, it's official, I need that.

this is great

They should use this for the new sr72 blackbird or as gaskets bw the titanium panels since the exterior acts as a fueselage for maximum fuel capacity and weight savings needed for hypersonic travel. As the previous sr71 had fuel leakage after high temp from flights would cause the titanium to warp. But this would allow fitting clearences to remain more precise in duty. Lockheed martin should look into this, if they havent already. Imagine if this alloy could combine w silicon to allow for elec flow, chip degradation and electronics reliabilty would greatly improve bc it would retain it shape from heat stress.

Thankzzz for this informative video 🔥

Love your channel. 👍👍👍❤❤❤❤

Nitinol is so cool

Why tf hasn’t all these discoveries changed all of people’s lives yet

Thanks for sharing!!!

This metal had better memory than me

Never heard about it, that's great, thanks RU-vid.

Seems like every time you hear “brilliant young scientist” these days it’s always a black and white photo.

I'm mad I didn't see this sooner. I spent a bunch of money on titanium frames for my glasses 😞

It's the material of the kid's spoon from the Matrix movie

You can definitely create free free free electricity from. Not entirely free of course but once created cost etc,. as structures combinations in staged levels and hooked up to generators in swarms let's say and then they can be used in seasonal daily weather conditions.

Que interesante es este material y creo que el ser humano es capaz de crear materiales o máquinas maravillosas

Nitinol sales on Alibaba have skyrocketed since this videos' upload.

FYI The files used for root canal treatment are made up of nitinol... They are called heat treated files

Kids: I'm the smart material Yes somehow you're right

Good content 👍

Trickled down, reverse engineered, ET tech I'd sugest

I feel like this video could have been three times as long with no filler tbh

The first thing that came to my mind was the scene from batman begins where fox explains the memory cloth

Tungsten holds the similar properties which are found in old bulbs

There's a reason this metal is not mass produced. It has very specific tasks and can not untangle itself.

It was developed by studying the material from the Roswell crashed in New Mexico

They found fragments of this metal on covid test strips.

Ok, so here are the materials for the elastomer muscle bundles found in the arms and legs of MechWarrior Mechs. Now we can make giant walking machines for multi terrain warfare. First comes science fiction then science fact. Never fails. Imagination is everything.

How does the property of metal ringing when it is dropped and hits the ground become a feature that you want in nose cones? That is, what characteristic is indicated by a ringing metal that makes it a potentially useful material for nose cones?

I bought a pair of nitinol glasses. They are good but expensive in my country. I think its better to buy cheaper ones and buy another pair if you break them rather than buying a pair of nitinol ones...

This material is cool

Where's my car? Certainly reduce insurance costs.

Like described during Roswell impact

Sciece is sooooo cool😎 Awsome metal💪

Thanks for naming it after me ..😅

Will this metal remember my birthday?

It would be nice to use that technique for the people who have their legs problems of concern. Some people have a really stiff legs, and some people have to wear specially tight socks and they cannot wear their shoes on by bending themselves easily anymore since they lost bending functions quite a lot. Is it possible to help patients with parkinson, as well as the people who cannot wear shoes with ribbons for men, women and kids? The shoe' thread type ribbons are great, but it would be nice to have the "alternatives" to have such "purposes to be able to survive as one of the survival solutions to be able to escape, in order to live to enjoy LIFE" by having such "flexibilities of shrinking functions "to serve the needs "to connect the LIFE of the ribbon to ABLE to "al" WALK"? I think, I saw such tie rubber like ribbon shoes for kids, but I don't think I have seen such "FUNCTIONS" for the WOMEN and MEN'S Shoes for their expensive working shoe laces 👞 👢 . Perhaps I should visit the shoe shop to see, if I have not only found it yet, by maybe I have not asked "the right questions". 🤔❤️😘 By the way, I was wondering if such particles of metals are in our body already applied? I don't want to my acquaintance to "throw away" the shoes, if we could save their shoes in finding this "alternative solution". I see, it will help men and wome greatly with their w-"al"-king shoes to literally be able to w-"al"-k. ❤️😊😘🤭

Hello Sir Good evening I have a request to you, Can you please make videos of all civil engineering test. Soil mechanics test are very helpful me and watched all videos.

I am a smart material. 😂 Lol the kid is 💥

Ive never seen or heard of anyone having Nitinol spectacles. I wonder why?

What was the plane in the video?

Strange uses? Iron Man suit, am I joke to you?

why is he credited with discovering it when he took the formulation from a book?

Reminds me of the roswell metal.

I thought they call it that cause it was made at night and all .

The NASA mars tire hasn’t launched into space yet but hopefully that will change soon.

Didn't know it was widely used

Would it be possible for the wheel to work on the Traxxas Xmaxx 8s rc car?

What kind of energy it is losing to get back to its original state??

Turbo flex eye glasses 🤣🤣

Why no one is mentioning nintinol engine?

you still didn't answer the question in the thumbnail. "How does the metals have the shape memory" ???

You know what's a good use for this? Key cards.

Getting some T1000 vibes over here.

Dude the whole time I was waiting for the big but, like how lead was a super alloy but, is toxic AF.

In advance, planet's 4 different lives,lessor 1's having seen this alloys cheej.

They could have simply named it North so that we could say The North Remembers

Molecules and possibly atoms that are grouped together 🤓

How do set the initial state of the metal

В СССР я смотрел про такие металы ещё в 80-х в детских передачах. Но в СССР жили самодостаточные люди считающие, что им всего хватает, что быть богатым плохо, работать нужно руками, а не инструментом, а проще сказать пьяные и необразованные люди. Сейчас таких большинство в россии и беларусии. Ин всего хватает, они покупают дешёвые китайские вещи, или старые бывшие в употреблении. Новые и дорогие им не нужны. Даже если у них есть деньги, они считают, что тратить их на современные удобные вещи глупо. Это тормозит прогресс. Многие даже не умеют пользоваться современной техникой. Многие способны только на механические действия выполняя однотипные операции на конвеере. Наверно это выгодно другим производителям - мы давно ничего не изобретаем, но поставляем дешёвую рабочую силу.

I think,Nitinol can transform prosthetics engineering and cyborg technology.

The army would certain ly be intressted in these wheels! Only a strong guess tho!

It is used in braces too

they call it witchcraft in medieval time when a nobody wear a nitinol armor thus they were burned on stake

I have a generator idea using nitinol.

Not to sound like a idiot but in the 1940s Roswell, NM UFO crash they found a metal that does the same thing. I wonder if this isnt reverse engineered
