Poly LMN: Nanomaterials for Making Stretchy Circuit Boards

[@reps]

I hope the forehead theory has been verified :)

[@joejoe4games]

If you use this stuff to make an antenna you could tune it by stretching it... lol

[@AlexanderBukh]

hey, frequency variation can be used to measure the stretch

[@EatRawGarlic]

You're one day ahead of me :) Maybe if you print a mesh on a flexible sheet, you can even use it as a parabolic reflector with a variable focus, by pulling a vacuum on one side.

[@Friendroid]

You could stretch it to fill a 1km wide impact crater on the moon

[@Bakamoichigei]

6:40 Can't wait to see Applied Science's video about making this stuff in his garage, the absolute mad scientist. 🤣 Great video, man! This is absolutely fascinating! 👍👍👍

[@CNLohr]

I was hoping for that, too. Maybe someday!

[@nikidino8]

Man you really need more recognizition, that is so awesome!

[@CNLohr]

You knoowwww you can share my video, and it'll get more recognition :-p

[@nikidino8]

@@CNLohr I already do ;)

[@Scrogan]

That could be very useful for putting an array of electrodes/sensors on something flexible, like on a human’s skin.

[@dummypg6129]

sorry i read it human foreskin. lol

[@wxifze]

@@dummypg6129 that's one of the possible applications

I was immediately thinking of medical sensors and wearable tech. Glad other people were too. Imagine your sleeve being able to take your pulse, measure blood oxygen, etc.

[@BHBalast]

Woah, this has a potential be be a really good electronic skin, just throw a this thing touch matrix, and you can envelop any surface (even elastic) in this! The second idea is to make 3-layer skin, 1. elastic matrix 2. Elastic isolator 3. Elastic matrix, this way the material would be able not only to sense touch, but also the pressure. Also this would be a great material for e-textiles.

[@BHBalast]

@Carl Thrasher (Capt) As I think about it it could be used for VR gloves, with some AI the pressure gradient of such "skin" could be transformed to individual finger tracking, and from the user standpoint, the glove would look just like normal elastic glove, maybe just with a few air wents and a rigid elements for electronics. That gaget would be a hot sell for around 300 USD, so with mass production of elastic circuits it could be done in the future. I think the electrical stimulation of the human skin in a predictable way is also possible. Great work, the possibilities for this tech are endless.

[@rngQ]

Gloves, clothing, etc. This is where it starts

[@UmbraAtrox_]

Hey youtube alghorythm time to start recommending this channel.

[@senwork4163]

Wooo I'm i dreaming ??? I love this kind of project bruuu. Y'all Awesome

[@MauroScomparin]

Pretty nice, no more breaking flex pcbs when over bent?

[@Buzzer]

I see many applications for this and so impressed by it, I think it would excel for wearable electronics. I reckon it would be the perfect material to make full hand tracking VR gloves that would be lightweight, compact, and comfy.

[@moncef0147]

The first thing i could think of is flexible stretchable oled screens, since one of the bigest issues is the stretching of the screen arount the bend because of it's radius, if the resolution is high enough they could easily compensate for the stretching in software.

[@AlexanderBukh]

very, very cool. i think, many practical applications will not require stretching it to the limits, as in: durability in small but frequent deformations goes a long way. another concern, how far could it be scaled down, for at this scale i think it can be replaced by fabric embedded flexible wiggly thin wires

[@AsbestosCrisis]

So awesome! This is a game changer for wearables!

[@artrock8175]

And we are officially one step closer to making the liquid metal terminator (T-1000) a reality! Terminator: Not like me. A T-1000. Advanced prototype. John: You mean more advanced than you are? Terminator: Yes. A mimetic polyalloy. John: What the hell does that mean? Terminator: Liquid metal.

[@Maxjoker98]

Wow, this is epic. Can't wait for my pants to smell my farts digitally :P Kidding aside, this is probably one of the coolest PCB's I've ever seen, and I actually can't wait until my pants can charge my phone.

[@CarlBugeja]

Wow! I'm definitely asking for a prototype!! Bdw just come across your channel 🙂 intreseting stuff!

[@CNLohr]

Thanks. Hope you like the content.

[@azinfidel6461]

Ty, reminds me how much I miss doing research. 💔

[@crackwitz]

now combine this with materials that stretch/contract when given some voltage

[@avibank]

Amazing content. Thank you!

[@kraklakvakve]

Stretch-tuning possible cause could be you mechanically straining the microcontroller itself - on the main board. Mike's Electric Stuff has a video on this effect in Microchip PICs.

[@guilhermealveslopes]

but it will be quite literally floppy eh

[@montenegro3167]

cool and crazy. a 3d circuit would make a wonderfull application (vase or similar).

[@Mil-Keeway]

That nanoliquid shouldn't be too hard to DIY even at home -> Gallium-Indium is available commercially as a liquid metal thermal conductor (like for CPU heatsinks) from various companies, ultrasonic parts cleaners can be bought cheap for household use, and stirrers can be found on ebay too. The carrier liquid is an unkown though.

[@CNLohr]

That's where the magic is :-p

[@4.0.4]

This is mind-blowing, I hope this becomes something commercial DIYers can tinker with.

[@CNLohr]

I can't wait.

[@sellicott]

Super cool as always!

[@kucingkeren8042]

if possible, I think it would be better if they add thread or fabric to limit the stretch

[@CNLohr]

That seems quite reasonable.

[@Stingpie]

is it possible to detect how streched the material is? that could be very useful for VR applications. You would just need to put on these LMN traces onto a glove, and then you could accurately track finger & hand position by how much the material has been streched.

[@davemarm]

If the resistance changes slightly and predictably as it is stretched then it should be possible.

[@johnuferbach9166]

@@davemarm Maybe you could also measure the distance with the run time of voltage?

[@CNLohr]

Ooorrrr sweeping a frequency down it and seeing how it attenuates.

[@geogeo3644]

[@colanuss4985]

Am i the only one, who is also impressed by the esp32 websocket realtime graphs? Have you uploaded it to Github?

[@CNLohr]

No, but glad I'm getting to this comment now, as I will have a version of that for the ESP32-C3. Or rather a version already but without graphs. github.com/cnlohr/esp32-c3-cntest

[@w4f7z]

Regarding the antenna de-tuning. I would suspect that it is also possible to create "stretch" sensors using not much more than a a few oscillators, orthogonal antennas, and a remote sdr.

[@CNLohr]

I totally agree!

[@cowofdeath777]

Hell ya

[@shanebekker]

Cool. Circuit skin...circuit skin...

[@eatonasher3398]

Couldn't you activate it using ultrasound instead of distorting it by stretching?

[@CNLohr]

I believe that is possible. Though you should totally reach out to them if you're interested.

[@nuovaheat1882]

Are you still working with these materials? I would be interested to have a discussion regarding a new device. How can we connect?

[@CNLohr]

I am not personally working on them, but The Poly LMN folks are continuing on!!! You can get sample quantities of their materials! You can reach them here: www.ues.com/elmnt
