Good to hear a brief comparison with FRORE Airjet. I recall in one previous interview, Frore mentioned that back pressure is an important metric for their cooling performance, and this one is about 60% of that of Airjet. Interested to see a real-world comparison when this MEMS chip is in production.

Kudos to interviewer for such a great question! That's peak critical thinking; if one is talking about arrays of smaller chips, the number of valves would indeed impact efficiency and design. Would be interesting to see if scaling up is actually practical when compared to a larger model.

This sounds like this could cause micro cracks in chips & cause interference related issues in chip with earths magnetic fields or even generate Eddy currents within chips due to nearby magnetic fields

I do wonder how airflow would work with smartphones when they've basically been trending towards sealing for water resistance purposes. If you're then opening up paths for airflow, how does that get dealt with in terms of water ingress.
It looks like this may be used to move heat away from the chips themselves to somewhere else within the device, likely a heatsink or similar, the hot air carrying that heat away. The point being it moves the heat away from where it will limit performance (like the surface of a chip), to somewhere where that heat is not going to cause a problem, like a heatsink or perhaps even to the outer casing of the phone (and then conduction pulls the heat out of the phone), but all this happens within a sealed device, rather than having open airflow in and out of the device. Just my guess.
@@raymonddsouza8948 air will never be as efficient as direct contact in terms of heat transfer. Hence my struggle to understand. I don't understand why you won't just use a heatpipe or graphene sheet or similar.
@@cassiohuithis is definitely more suited towards consumer electronics that doesnt need ingress protection, this technology would definitely replace the traditional heatsink + small fan combo in smaller devices such as a microcontroller, no way this would replace vapor chamber for smartphones anytime soon.

I didn't bring this up, but xMEMS says that it's IP58 dust- and moisture-resistant. To be honest, the IP specs don't seem to go into too much detail as to what that means in terms of particulate size and so on. It's a good question, though.

@@soulsbourne Piezoelectrics do not use magnetic force, and besides, the electronics inside a phone are already exposed to tons of rapidly varying magnetic and electric fields.
8 inch wafers means +130nm, 180/250/350nm. The 8in to 12in transition was in the early 2000's and 130nm and 90nm where the "new" processes during the transition period.
In standard lithography, you are absolutely right and you present a good summary, however, MEMS wafers are specifically designed for micro-electromechanical systems. They have different properties, such as thickness, positive photoresist coatings, and additional layers, to accommodate the MEMS - 1nm min feature 0.5 μm - fabrication processes. Handling and processing ultra-thin MEMS wafers often require special tools like carrier wafers or support wafers, typically blank plates.
The silicon-on-insulator micromachining PiezoMUMPs process has the following general features: 1. A silicon-on-insulator (SOI) wafer is used as the starting substrate. The substrate has the following characteristics: • 150 mm (100) oriented SOI wafer. o Silicon thickness: 10 ± 1 µm o Oxide thickness: 1 ± 0.05 µm o Handle wafer (Substrate) thickness: 400 ± 5 µm 2. The Silicon layer is doped, then patterned and etched down to the Oxide layer. This layer can be used for mechanical structures, resistor structures, and/or electrical routing. 3. The Substrate can be patterned and etched from the “bottom” side to the Oxide layer. This allows for through-hole structures. 4. A thermal oxide layer is patterned and etched to provide isolation between the SOI layer and the AlN and PadMetal layers. 5. A piezoelectric layer, AlN, allows for the development of piezoelectric sensors. 6. A pad-metal feature that allows finer metal features and precision alignment but limited to areas not etched in the silicon device layer.
they get straight to the point, and offer real functionality. I really look forward to this device being adopted and used widely by mobile phone companies.
integrating this inside a low profile nvme m.2 ssd would be a gamechanger for cooling the controller without relying on external airflow to stop throttling and manage the drive's endurance. Of course, vibrations would be a factor to consider
I was thinking the same. With vents providing openings, this definitely my first concern. Maybe the vented areas are sealed off separately from everything else that doesn’t need to be cooled as much.
@@miniVoo Good idea. However wouldn't they still leave the cooler itself prone to getting clogged? I suppose as long as it could be cleaned with compressed air or a light rinse it would be ok, I'm just curious because they didn't mention it in the video.
This is actually really really cool. My main concern has nothing to do with the product, but rather with the smartphone manufacturers that will refuse to implement it because it might not allow waterproofing or create a single 1mm slot in the phone's shell that gives designers an aneurysm. Although perhaps merely moving the heat somewhere else inside the shell might be an advantage already.
Dude.. awesome idea! Let's take it up a notch and sandwich a peltier component in between the chip and mems cooler and you'll have such a killer product.
Integrated cooling via 3D stacking would certainly be interesting for a big efficiency gain in power and area utilization. Given the limited surface area, I'm certain it will always be limited to very lower power chips though.
With how hot some of the fastest SSD's are getting. If they could collaborate with the right companies, this would be a fantastic opportunity to get rid of the potential overheating problem. And even if it costs a bit extra, most people only need the fastest SSD's for their OS so then Windows will run faster and more responsive. People can still get the cheaper/ slightly slower less hot SSD's for expanding storage. So it should realistically not add that much cost to a PC, I'm sure laptops could greatly benefit from this cooling technology.
Will you need two openings in the phone to let out the hot air and replace it with cold air, but this will only make you IP68. Or do you make this piece waterproof?
The specs seem pretty insane. 39 times smaller than AirJet but at 39% the airflow. Stack 3 of these and it wins across the board. I'm curious what the sound profile is like, especially at higher capacities.
I have my doubts that it would scale linearly or that heat removal is as efficient as Frore (it generates significantly less backplane pressure, which is presumably the critical variable that affects heat removal), but in mobile devices where heatsinking into the LCD successfully removes quite a bit of the heat and SoC power usage rarely goes above 5W, this could be a total game changer for improving the performance envelope. Most SoCs won't even go above 50-60C inside the core in order to prevent heat buildup from making holding the device uncomfortable -- with active heat removal, they could probably allow them to turbo up to 70-80C without affecting the skin-temperature feel of the device. Probably will be a game changer for preventing battery degradation and getting local AI chatbots running on mobile devices within the next couple of years.
I really appreciate the tech you are dealing in and its huge, but I have one question: What about dust? in general, the PC fan get dirty and we just open it and clean it once or twice a year. I hope it blow the air out of the device at certain level, if this chip is not ready for blowing the air out of the device then what is the point of circulating hot air inside the device!
It doesn't need any power Mr powers, you just charge capacitors in sequence using prime lattice 7 x 1,000uf -> 11 x 500uf -> 13 x 250uf -> 17 x 125uf -> 19 x 63uf -> 23 x 31uf -> 29 x 15uf, just has to be half, one series array to full multiplier at 220v 200mhz, because capacitors just store voltage, especially small ones. Going by half is the most efficient cycle using less than one arrays worth for any size array, just has to be PNP. The prime offset makes the full multiplier always discoherent in every four stages forcing the charge pump with 558 timer logics.
I wonder how good these are inside a sealed phone, or will this require some holes to work? And will it cancel the big gains in water protection rating?
Perhaps it would be possible to have a tiny heat pipe or even a more simple metal plate to deliver the heat from the main sealed body into a very small non sealed cavity in from which it would circulate the air? Just an idea, I have no knowledge to base this concept off.
I think there is an issue with approaching smartphone cooling given the ever greater emphasis on efficiency in smartphones. We want more performance, but we can't very well increase the power because we dont want a larger battery, so that means we want more performance at the same power... Active cooling will still require some additional power to run and will thus provide a worse experience on smartphones that tend to already have rather limited battery lifes.
I'm skeptical how something 1mm would effectively cool a phone because they are talking about cooling the chip by getting small areas but it's not just the chip that heats up, it's also the body. So I'm curious how this chip would stand up to laws of thermodynamics.
Not too fast without proper testing. What happens if they get plugged with dust, degradation lifetime and power to cooling efficiency compared to other methods?
I'm interested to see how this tech can go. I wonder how good the audio is of headphones that use it compared to other methods. Also for chiplet cooling, how efficient is it as far as power and airflow compared to fans? I wonder how long these things can last without degrading or is there a chance in some months of using it for cooling they can get plugged up with dust? If they did get plugged with dust, can they easily be cleaned?
Newtons pSI measured in LBS - lol sound and micro thermals at the nanoscale in MEMS/NEMS measurement of pressure, use "minute differential pressure sensors" (MDPS's), resonant MEMS pressure sensors are the most accurate and stable pressure sensors available. In a counterintuitive paradigm shift that turns intrinsic thermal noise from an impediment to a constituent of the sensor by harvesting it as the driving force, obviating the need for external actuation and realizing ‘noise-driven’ sensors, microspeakers and microcoolers, is what is being discussed, not drag racing cars! 🤣
That would be an interesting concept with MEMs. They have basically been working on a similar idea since the 90's with microchannels, the silicon itself being the cooling block, but never really went anywhere. The idea got new life in ~2010 thanks to 3d stacking. It was thought that it would be a good way to remove heat from chip stacks.
This is nice tech but whats the tolerance die micro vibrations produced by ultrasonic pulse would it be safe for the chips they are cooling what if there are micro fractures due to it and make a soc useless it should be tested
The thing is that after all these years and all the promise of these things, Frore’s AirJet product is still not widely deployed out in the field. Not sure what the holdup is on this tech.
Well this technology opens up a lot possibility” with physical activity at the micro level” we can use this to also generate energy to power the microprocessor, we could have self powered microchips, we could one day have phones 📱 that don’t require charging 😮
I don't think phones need this at the moment. 95% of phones are doing well enough with passive cooling and have more than enough performance by a factor of x2. However, ... bring this tech to laptops already. GOD DAMN ! It's been almost 5years.

Active cooling will still require some additional power to run and will thus provide a worse experience on smartphones that tend to already have rather limited battery lifes.
True but this is different I've herd it doesn't take much power at all from the battery and it's small for a reason imo that's impressive
It consumes less than a watt don't think it even matters
Now this one is looking much more interesting unlike the first one claiming it can cool without air vents according to the guy that presented it.
I'm skeptical how something 1mm would effectively cool a phone because they are talking about cooling the chip by getting small areas but it's not just the chip that heats up, it's also the body.
So I'm curious how this chip would stand up to laws of thermodynamics.
Please sell this to tsmc they will make it industry standard
hope it goes mainstream fast
Not too fast without proper testing. What happens if they get plugged with dust, degradation lifetime and power to cooling efficiency compared to other methods?
I really interested in this technology and wait it to spread aout
How loud is it?
Can this technology also move liquids?
I'm interested to see how this tech can go. I wonder how good the audio is of headphones that use it compared to other methods. Also for chiplet cooling, how efficient is it as far as power and airflow compared to fans? I wonder how long these things can last without degrading or is there a chance in some months of using it for cooling they can get plugged up with dust? If they did get plugged with dust, can they easily be cleaned?
WOW! looks really good.
Slap that in gaming handheld, and it'll be a banger
Should have a little fin at the end to direct the air away from mother board
soo what, do we get new headphone technology ? Also could we build supermall and compact and silent vacuum cleaners with this?
That is fucking awesome
Would love this and airjet to be available on CPU and GPU applications
What is the max newtons thrust from one of these chips?
Newtons pSI measured in LBS - lol sound and micro thermals at the nanoscale in MEMS/NEMS measurement of pressure, use "minute differential pressure sensors" (MDPS's), resonant MEMS pressure sensors are the most accurate and stable pressure sensors available. In a counterintuitive paradigm shift that turns intrinsic thermal noise from an impediment to a constituent of the sensor by harvesting it as the driving force, obviating the need for external actuation and realizing ‘noise-driven’ sensors, microspeakers and microcoolers, is what is being discussed, not drag racing cars! 🤣
noctua, hire this man
Is this for air only or could they also pump a thin cooling liquid?
Proper competition going on chip air cooling.
maybe cooling the CPU won't be an issue in future.
Keep supporting both FRORE and MEMS then.
5:08 I guess that kind of true, redmagic is the only phones I know that has a built-in cooling fan.
There were the legion phones too.
I want to know one thing, will this affect the water resistance of devices?
any words or reliability of that cooling chip?
scale this up and we can have truly SILENT fans
Imagine a thin liquid cooling block powered by the MEMS... a CPU liquid cooling block being its own pump :)
That would be an interesting concept with MEMs.
They have basically been working on a similar idea since the 90's with microchannels, the silicon itself being the cooling block, but never really went anywhere.
The idea got new life in ~2010 thanks to 3d stacking. It was thought that it would be a good way to remove heat from chip stacks.
What's the efficiency like? Obviously if the thing has low efficiency it will generate heat and may have little value.
Tam tersine yapsalar soğuk havayı alttan alıp yukarıdan verseler. Böylelikle diğer kompanentlerden ısınmış hava uzaklaştırılmış olur
This is nice tech but whats the tolerance die micro vibrations produced by ultrasonic pulse would it be safe for the chips they are cooling what if there are micro fractures due to it and make a soc useless it should be tested
Make an NVMe heatsink, xMEMs & Frore! Esp for desktop users, this would be minimal power draw for a big win.
Murata were doing very similar 20 yrs ago, have the patents run out.
pretty sure some other people called him Professor X. and he is xMEMS right?
Follow your instincts. That is where true wisdom manifests itself.
Can this technology be used for active aero control on vehicles? More energy-efficient cars and longer range airplanes, for example.
Might need a conductor to release the heat to the environment, as mobile phones are typically water resistant, so external airflow near non existant.
The thing is that after all these years and all the promise of these things, Frore’s AirJet product is still not widely deployed out in the field. Not sure what the holdup is on this tech.
I'd love to see this in a DAP, those things get hot.
with most phones being waterproof now, how would this be effective if the chip has nowhere to exhaust the heat out of the device?
what about water proof phones, if the whole phone is sealed so that water cant get in, how the hot air will come out from those phones?
What lies behind us and what lies before us are tiny matters compared to what lies within us.
That's cool
definitely sounds similar to AirJet cooling chip
Well this technology opens up a lot possibility” with physical activity at the micro level” we can use this to also generate energy to power the microprocessor, we could have self powered microchips, we could one day have phones 📱 that don’t require charging 😮
Sounds like a dream 😅
I don't think it can be reversed to act as a generator.
Super cool!
One of the problem about smartphone, they are used in harsh enviroment. Waterproof may not as good as before.
"It's really cool, 1 mm thin" - I see what you did there.
Whats the difference between this and Frore systems?
So we add moving to the phone
So how much is this going to cost repair
I don't think phones need this at the moment. 95% of phones are doing well enough with passive cooling and have more than enough performance by a factor of x2.
However, ... bring this tech to laptops already. GOD DAMN ! It's been almost 5years.
But how do you clean it when it clogs up with dust and hair?
