The World Of Microscopic Machines
HTML-код
- Опубликовано: 22 май 2024
- Micro-electromechanical systems or MEMS are tiny integrated devices that combine mechanical and electrical components. Traditional manufacturing techniques such as milling, turning, and molding become impractical at small scales so MEMS devices are fabricated using the same batch processing techniques used to fabricate integrated circuits. These devices can range in size from a few microns to several millimeters.
Because MEMS devices are a hybrid of mechanical and electronic mechanisms, they’re generally fabricated using a combination of traditional integrated circuit technologies and more sophisticated methods that manipulate both silicon and other substrates in a manner that exploit their mechanical properties.
In bulk micromachining, the substrate is removed in a manner similar to traditional integrated circuit techniques.
Surface micromachining, by comparison, is a predominantly additive in nature and is used to create more complex MEMS-based machinery. Material is deposited on the surface of the substrate in layers of thin films.
High-aspect-ratio micromachining differs dramatically from the other two techniques in that it’s reminiscent of traditional casting.
The accelerometers used in automotive airbag sensors were one of the first commercial devices using MEMS technology. In widespread use today, they measure the rapid deceleration of a vehicle upon hitting an object by sensing a change in voltage. Based on the rate of this voltage change, the on-die circuity subsequently sends a signal to trigger the airbag’s explosive charge.
In most smartphones, a MEMS-based gyroscope complement the accelerometer. They’re also found in navigation equipment, avionics and virtually any modern device that requires rotation sensing. MEMS gyroscopes work by suspending an accelerometer on a platform that in itself uses a MEMS-based solenoid to create a constant oscillating motion.
Another hugely successful application of MEMS technology is the inkjet printer head. Inkjet printers use a series of nozzles to spray drops of ink directly on to a medium. Depending on the type of inkjet printer, two popular MEMS technologies are used to accomplish this; thermal and piezoelectric.
DLP
One of the earliest uses of MEMS devices in the form of large mechanical arrays on a single-die has been for display applications. Invented by Texas Instruments. Each pixel is made of a multi-layered device consisting of an aluminum mirror mounted on hinges. These pixels rest on a CMOS memory cell.
Digital micromirror devices form the basis for another emerging application of MEMS technology, electro-optics. These bottlenecks can be eliminated by using fully optical networks that offer far superior throughput capabilities.
One of the more promising applications of MEMS technologies has been the emergence of biomedical MEMS devices. Referred to as Bio-MEMS devices, they tend to focus on the processing of fluids at microscopic scales.
One of the first and simplest examples of a bio-MEMS device is the micro=machined microtiter plate. A microtiter plate is a flat plate with multiple wells used as small test tubes for testing and analysis.
The possibilities with MEMS devices are astounding. Applications from low-loss, ultra-miniature and highly integrated tracking radio antennas to sensors that can measure heat, radiation, light, acoustics, pressure, motion and even detect chemicals.

One of the few times when RUclips recommendations lead to gold.
Pb to Au? Sounds about right to me 😁😂
@@danielmacbride525 RUclips is the best alchemist
Beans are tasty though
This absolutely is some of the most mind blowing modern science that the vast majority of the world is completely clueless about........... presented perfectly for us dumb people. Amazing presentation!!!!!
You aint seen nothing yet. www.sciencedaily.com/releases/2018/05/180523104300.htm
It’s difficult to realize what it is we’ve already created, yet we’re still going higher and higher...
I'm smart
Some people rather waste time in church (religion),
others spend time trying to study and experiment newer advancements in technology or biological fields(science)
This is shit to us learned people.
When I clicked on this video, I expected a futuristic idea.
Turns out it's already happened
Right?!
FIFY
*Turns out it's already happening
@@chaomatic5328 it was on porpuse. think twice.
@@brunolidade *Barely resists the urge to correct porpuse to purpose*
Jokes aside, we usually say "Turns out it's already happening". I guess that the "it's already happened" would be ok if it wasn't for the " 's" ("it is already happened." That's not how grammar work :P)!
Thinking the same thing. It's like you think its cutting edge and then find out it's invented 20 years ago.
As an engineer I have high respect for the knowledge and research put into this video 👌 I'm only an RF engineer but I require endless amounts and types of MEMS for radio frequency devices to work the way this modern world needs from micro-microphones to data transfer and tilt sensors on sat dishes. This was a very enjoyable video and I appreciate it 😎
Wow, I did research in a small branch of MEMS for my master's thesis, and this video still told me a lot that I didn't know. I can't imagine how much work went into this. Spectacular educational video.
Your comment put into perspective the amount of data this guy gathered into one video and presented spectacularly. Really makes me appreciate people like him.
Brilliant comment. Someone who is qualified to provide evaluative feedback. Unlike myself as this video is so far above my knowledge level but still very engaging-
Exactly who can think up the processes to make such things!!?? Amazing simply amazing...
This channel is so underrated
yes
David B I was just gonna comment that
It's getting better fast, and the growth reflects that nicely :)
I discovered this channel today!
I agree wholeheartedly. This channel earned my sub before I even finished the first video I saw. I like that he isn't scared to go into technical detail, or have a video that's longer than 5 minutes. So many channels are doing this these days and it doesn't even feel worth the effort to watch a 2 minute video about something I'm interested in. It's just a tease. If you're interested in the content, shouldn't a long video be a good thing?
0:48 Believe or not, that dust mite is our best employee of the week. Hes so focused on fixing that wheel gear, completely not noticing somebody is taking picture of him.
And now he is famous on the Internet, we are so proud of him, as long as he will not asking for a raise because of this, of course.
1:22
Now its demanding free healthcare, paid sick leave and equal pay as the humans...
Thanks alot
@@deafmusician2 Saw it with a sign... Will work for molecules...
Are you sure it wasn't just 'performing' because he knew he was on camera? :-)
The needle just utterly brutalised that blood cell at 15:45
Do we need to call the police for physical assault ?
Lol it’s like ooh, ooh, it won’t go in, just a little more, no, wait, BOOM
Anthony Paull yes
When you're that needle
@@renosgarage7451 go easy, it's my first time
I'd love to see more about Microfluidic devices! Physics at that level is completely unintuitive (liquids flow with 0 turbulence!), and I'm vaguely aware of a few applications: separating cancer cells from blood samples, creating micro bubbles to contain chemical reactions, "labs on chips", electrostatic+microfluidics to move chemicals around ad lib and react them in interesting ways... YT is a bit poor in this area, and the world needs more!
holy! micro bubbles! you can make logic gates with those! you can make a biological digital computer with that.
You’re proof that there is still more talent to discover!
Somewhat of a meaningless statement.
噢馬 let me help you there mate, the meaning of the statement was to show my overall enjoyment with the content put forth by this channel.
Ain't ya mate, yet the talent you seem to be applauding is the ability to read and coalesce consumable understanding.
I mean he most likely got all of these techniques from a scientific journal and a few hours of wiki searches.
噢馬 Thank you for pointing all this out 😘
It's called hard work, buddy.
You hear "nano tech"... Then you SEE nano tech! This blew my mind.
To be honest most of this is micro technology, nanotech is 1000 times smaller than that
Nanotech is just weird, you have to take into account quantum physics and is less used at the moment
Those are MEMS. Look into NEMS, for the true nano electro mechanical systems. it's just plain crazy what we can achieve :)
The amount of information, examples and visualizations that you have in each of your videos is amazing. You must do a lot of research on each topic. Great work.
I remember learning about this because I accidentally wrote mems instead of memes
Funny that you read more about it :p
Always wondered how my phone knows which way is up!
Duh.
Seems like something I would do
Awesome content, I'm glad that RUclips recommended you to me
Same. I'm new/instant fan!!
RUclips did it again.
RUclips is truly the greatest learning resource ever created on this planet. Thanks for being a part of that.
I've read about MEMS before but never really understand it then this video happened. Very concise, to-the-point, and easy to understand! Good work man.
It's mindboggling how much technology has evolved since I was a kid and I'm only 43.
It is amazing, isn't it?
OK, Boomer 😅 (j/k I'm 42)
Since 1944 I have seen the development of: transistors, integrated circuits, lasers (and laser diodes), light emitting diodes of all colors, a "computer on a chip," electronic gyroscopes and accelerometers, flat screen TV and computer monitors, touch screens, and not least, a credit card with a chip.
I saw the transition from monaural vinyl records to long-play stereo albums, and then magnetic tape (like 8 track cassettes), to CD's and video discs, all of which is now obsolete.
And of course, GPS, smart phones, and the internet. It has been amazing to watch! The thing that has impacted me most is the internet and the availability of information. Back in the day, you had to go to the library and look stuff up!
Don't call me "Boomer!" I'm older than those young whipper snappers.

Props, pops... Veneration for your generation.
It's amazing what yourself/my parents/et al have been positioned in history to witness, 'techno-culturally', i guess I'll call it. The perspective of each generation is indeed largely unique, and yours was, in this sense, a special generation among ALL of them.
Do you remember 5.25 inch disk drives with that clip to keep the disk in place? You had to turn the clip through 90 degrees.
As a master at Microelectronics and Optronics and aerospace engineer I must admit that this is seriously well prepared, entry level presentation for people that might want to sink in a micro world of MEMS/MOEMS.
Do you have any recommendations for going further? After watching this video, I think I want to go into this field. It fits perfect for my majors.
MEMS was emerging when I started my Ph.D. in it, over 25 years ago. Most, if not all, of the pictures shown of the rotating wheels etc. are from that time. It was great fun to work in that field and I’m very happy that I had the opportunity to work in one of the leading groups at the time.
2:10 the wafer itself is a slice (literally a wafer) of monocrystalline silicon. it is not coated in silicon. you also got your labelling of positive/negative photoresist exactly backwards. upon UV exposure, a positive PR will wash away during development while a negative PR becomes insoluble. the way to remember it is that after exposure and development, a positive PR becomes a copy of the UV mask, while a negative PR becomes the negative copy of the UV mask. in traditional film photography the light exposed parts precipitate silver and become insoluble to developer so the lightest part of the picture is the darkest (that's why developed film is called a negative). also doping is not done through oxide. that is etched off first.
Follow Media He could have gotten away with that if it weren’t for you.
Every single thing you said is actually unequivocally false.
Dude... I’m here before your channel explodes. Remember the little people.
Another excellent video! I am again impressed. I am also shocked at the few subscribers. Don’t give up. Quality videos like these will eventually catch on with people and rise up in the numbers.

"If you're not cops, you're little people!"
You are the new Wendover Productions, and as with Wendover, I'm glad I found your channel when you had less than a few thousands subscribers.
Keep up with this quality and you will soon reach the same subscribers as real engineering, Wendover and real life lore
Currently doing undergraduate research on silicone nanomembranes :) it took me about a year to get what some of the things described in this video are. Great video keep it up!
great! thanks for the unintended support
practically all of it went over my head
and I thought iyam too dumw to get it
are those any good for making mics
The airbag videos are so gentle and soft and not reminiscent of my finger being broken, my arm having chunks of skin ripped away, and the explosion of my own experience with airbags going off.
What an excellent video! So much information, well researched and compressed into 16 minutes. Love this channel!
Not only was this a fantastically informative video which kept me gripped for its entirety, I’d forgotten how wonderful it is to NOT have music in the background distracting and confusing what is being said. its absence was a bliss that I was unaware I required 10/10 you have a new subscriber good sir!!
I am thoroughly impressed with mems technology and all of the various applications in use and under development. That being said, 15:30 was a curve-ball I wasn't expecting. Thank you for delivering that near the end.
One of the best videos to give a glimpse of the state of the art technology in MEMS. Thank you so much for this magnificent video. Mind-blowing presentation
Another very common application of MEMS is the filters in the RF frontends inside our phones. A lot of microphones in computers and phones these days are usually MEMS too.
I wouldnt call saw filters mems devices neccessarily
@@BrosBrothersLP They are MEMS devices in operation, and manufactured by photolithography. The only reason they are not called MEMS is that they predate the term.
@@vylbird8014 i would disagree. As their is no part that gives. Its just a vibrating chunk
@@BrosBrothersLP In English the words THERE and THEIR are spelled differently because they mean different things.
@@MrCuddlyable3 that was a neccesary comment? I think everyone understood what i meant
Simply amazing overview/in-depth review of the entire field which I wasn't really aware of, until now!
Thank you so much!
Much love!
Thank you! - You’re channel makes complicated subjects so understandable - it’s fascinating.
I love how symmetrical and perfect all the little gears and rods are. Also, how quickly do the moving parts wear down with them being so small?
This is by far the most outstanding thing I have seen this whole month. Amazing video, I'm now really intrigued by this subject.
I am studying this and I still get fascinated pretty frequently by new awesome chips&technologies
Dude your production value is far beyond this channels size. Excellent knowledge and commentary, high quality self-made animations, and the rest of the clips are perfect for what you are explaining. I hope this channel blows up soon
What a pleasure to get recommended a video which describes all the things I study at the moment and want to work with in future. Material Science with focus on semiconductor technology is such a futuritic field.
Also MEMS
We were so close to greatness
U mean Memes?
sutarno tarno, yes my dude
Micro electrical mechanical engineered systems.
Nano tech son the MEMS
there is no HARM to making MEMs anyways
Finally, another channel I can binge watch all day, thanks for the awesome content!
Amazing. This video brought together several topics that I've heard about over the years, but never thought were related. Keep up the great work !
Amazing. I m stunnn. This is what called engineering. Hats off to all those great minds.
honestly shocked how mcuh stress these can take. Same with mocro complient mechanisms. Great video. Great channel keep it up
My horizon did get just a little brighter, thnxs for your efforts to make this happen.
This is one of the most fascinating things I have ever seen!
Many thanks to the narrator for explaining these complex issues in a readily accessible manner.
Omg I'm writing my senior thesis on RF MEMS and this was super helpful. It was just recommended to me. Would love to see how some MEMS work in more detail. Thanks again, nice content!
You will have 500k subs by next year for sure. Maybe even over 1mil. Your content is INCREDIBLE. Thank you so much for your effort
Very informative and well made video! Keep em coming! 💪
Amazing video! One of my favorites recently. Well done!
I've watched this several times and it never gets old! Absolutely mind altering.
Definately subscribed. This is the first video I've watched on your channel. I'm STUNNED. WOW. First bringing real life examples, than explaining the subject and going into detail. I imagine that this video took weeks to make and the detail is just amazing. Thanks for making RUclips better
Brilliant. This video was so educational since I'm studying mechanical engineering (first year) it was really fun to explore this new production method. Keep up the good work!
I might have just found my new favorite channel
This channel is pure gold!!! Great stuff here
Honestly, this is a terrific channel. Your videos are wonderfully done, definitely on the level of quality (or even surpassing that) of most of the sponsored or Patreon based channels. This channel definitely deserves to be sponsored by Brilliant, Curiosity Stream or one of the other scientific oriented commonly-seen sponsors found on RUclips. Excellent content and please keep up the wonderful work :)
_Sooo,_ I was searching for "Apollo Flight Journal" and RUclips recommended your channel. I guess the algorithm knew I'd like your content, and it was right! I've already watched several of your amazing videos _and_ I subscribed! 👍🏻
*All hail the algorithm!* 🙏🏻
Out worldly perhaps. Best possible video for detailed understanding. Loved it.
Worth watching.
These videos are godly. I predict < 1 Year until this is one of the top educational channels on RUclips.
Excellent video! This is the kind of content I'm always looking for. Subbed!!
Bruh!!! I subscribed to your channel in a heartbeat!
Keep up the good work, subscribers will follow.
Top quality, explains some fascinations i've long had; now the mystery of how these work is less cloudy
This was beautifully presented and kept my attention fiercely. My eyes kept widening and my mouth even dropped open.
Brilliant thank you for the knowledge, and the education.
But still my android phone takes 8 minutes to notice I've switched to landscape 🤷♂️
Same here xd
(And that is why iPhone is better)
@@ThylineTheGay iPhone takes just as long, and uses the same chip. It's seriously fucking forever, it takes 3-4 seconds ever since they switched from accelerometer to gyro and accelerometer. I get it works better in shaky environments but still
HAHA!
My Huawei takes about a half second.
But some times its more lile minutes or not at all 😅
I think this was perhaps the single most informative thing I've ever seen. Much of this being understood already at a surface level, but seeing this so clearly and so simply conveyed... So many things that were just accepted to "do what those things do", are now understood... The inner how's and why's are known. And that's pretty dang neat! Thanks man... subscribed!
Dude thank you! This was a rollercoaster of shock and awe! More on this, no one's talking about this stuff!
Again great content man, this channel will blowup any day now. Interesting topic too, cool stuff. Keep it up man, don't let anyone tell you you're doing it wrong
Great video!
However I think at 2:29 it is the other way round.
Positive photoresist: Exposure to UV-light increases soluability
Negative photoresist: Shielded areas from UV-light get dissolved during development
Thank goodness I'm not the only one who noticed
I'm glad you pointed it out -- it's a good video, but there are errors in there. There's the description of a "wafer being coated with silicon", which isn't accurate -- the wafer IS silicon. And boron bombardment isn't a photolithography technique, it's called ion implant.
@@4422011 Thanks for your additions :)
Mind Blown! I didn't even imagine something like this possible.
The amount of information was like a flood gate bursting in my face.
This is really high quality! You need more subscribers!
Just wanna say thank you for this. I learned A LOT
Nice work.
I appreciated knowing the manufacturing methods and seeing such a wide range of applications. I think further exploration of the future of this field would be excellent. If you are up for it, even getting in touch with a top academic in the field with 5-10 questions would be a welcome addition. Keep it up mate.
Amazing. Fascinating. Well explained. Thank you
Wow, this channel is just amazing! It really open my minds about how tiny stuff were manufactured.
Wow. This mems stuff is pretty interesting. I'd love to see a mems contact lens with display or something like that. Great potential for huge success in this field in the future I would say.
One of the BEST science channels! Great job & thank you for your terrific videos!
So glad I found this channel. Loving every video I've seen.
Incredible! After seeing this I feel like I have just walked in from the cave. Thanks.
I am glad that i found this channel ♥️💜
Beautiful video. It's rare to see such detailed footage of these micro-technologies.
Keep up with your work!! You will get everything you deserve for being so talented!! A huge fan from Argentina!
Blows my mind how advanced humans are at some things, while being completely stone aged about others.
I'm studying MEMS at university and even I learned something from this video.
Thank you and good job!
Have you ever done a live stream on your research process? It sounds like it would be super interesting to watch.
Your doing such a good job. This could be a 4 hour video and would still contain too much information to comprehend. But don’t water it down. I may have to replay the video 10 times to fully understand them but man it’s worth it!
We are living in the future. What a time to be alive
This topic is well timed with the Neuro Link announcement a few days ago!
Again and again you hit it out of the park! Thank you
Just discovered your channel and it's awesome. Your videos are so diverse and very educational. It's always what I'm looking for. The narration is also superb. 👍
WOW, ok officially blown away, you could make several shows about what you just quickly went over.
That's for this video I always wondered how mobile gyroscopes.work
I'm just attending the first lecture in Microsystem Technology. This video relates closely and helps me to understand what MEMS is. Thank you!
These videos are amazing. Each better than the previous, with comprehensive insight and easy to understand facts. I know how hard it is to make something difficult and present it so that a vast majority will understand. This is just pure talent. Hope you reach the stars with this channel!
"bubble jet" - Now there's a word I haven't heard for a long time!
Still used a lot in industry and the food industry.
This is the sort channel that normally has 1.5 mil subs, instead of 70k 😂
This is one of the best informative channel I have seen, subscription should be more than 5 millions.
You just answered so many questions I had in life...and created many many more questions! Thank you for the video.
I thought the video was SUPER fascinating from the get-go - then out of nowhere you throw in the reason where bubble jets printers gets there name from and my brain exploded.
A shame that all these inventions are not known to the mainstream and neither are the designers and inventors :/
So fascinating! Great production and illustrations!!
wow this is such a well made video. I hope you soon get the kind of audience you deserve for all the work it seems you put in this stuff!!!
Don't mind me, i'm just here to see this channel blow up.
