As satellites become critical infrastructure, they need compact and reliable mechanisms to deploy solar panels or antennas, release payloads and operate safely in orbit. In this live demo, Nimesis will show how shape memory alloy actuators can replace traditional devices with lighter, ultra compact, ground testable, non-explosive and ITAR-free solutions. From material to qualified actuator, the session demonstrates a European industrial approach for cleaner, safer and more scalable space systems.

00:21Good morning, good morning, good morning, everyone.
00:27Yes, I have a lot of energy this morning.
00:30Welcome back to the Discovery Stage.
00:33Day 3, day 3, day 3.
00:36Yes, we are in.
00:38For those of you joining us for the first time today, welcome.
00:44My name is Eric.
00:45I'm your host for this stage.
00:47And for those of you watching us live, thank you for joining us.
00:52Yesterday, we covered energy, climates, and health.
00:58Today is bigger.
01:01Space, quantum, computing, AI, frontier technology.
01:07Things some people still call science fiction.
01:12They are wrong, ladies and gentlemen.
01:15Nine demos this morning, all in a tech beyond the obvious team.
01:21And this afternoon, we move to creative, cultural innovation, a full day.
01:28Ten minutes per startup.
01:30Real demos, real founders, live here at the Discovery Stage.
01:36Let's start with the first one.
01:38Our first guest is Nemesis Technology, a French startup.
01:42They built a smart actuator for satellites using shape memories,
01:49alloys a special metal that changes form on command.
01:54Their tools are what unlock antennas and solar panels once a satellite reaches orbit.
02:02Ladies and gentlemen, please welcome Alain Auker and Fabia Villigue from Nemesis Technology.
02:13Gentlemen, the floor is yours.
02:16Hello, hello.
02:17How are you?
02:17Good morning.
02:21Good morning.
02:22Good morning, ladies and gentlemen.
02:23Fabia Villigue, Nemesis Technology, and Alain Auker, our CEO, founder.
02:28We are happy to open the session today.
02:31We will start immediately with the demo because what matters is not only what we say,
02:36but also what you can see.
02:39So what you see here on the desk is a satellite mock-up.
02:43What we will show during the demo is the solar panel opening,
02:49so the deployment of the solar panel, what Nemesis Technology is developing,
02:53are mechanisms to open all various parts that move on a satellite,
02:59so either a solar panel, antennas for communication, masks, or some payloads.
03:08We have installed different actuators on the system,
03:12so the trigger time is slightly different.
03:14The technology is all the same.
03:16We are going to come to that in a minute.
03:20So now here was a show the satellite now, once launched, would be fully operational.
03:29So what did just happen?
03:32First, when you launch a spacecraft,
03:35what is very important is that all the moving parts are totally locked during the launch,
03:41because during launch, the vibration level can go up to 50 G,
03:45so in order to not destroy any of those parts, they need to be very firmly hold.
03:51Then there is a command, which is electrical in our case,
03:55so we heat our material, and then it unlocks the system for finally deploying the payload and the antenna,
04:05or in our case, the solar panel.
04:09So the actuators themselves are really small,
04:13but if they don't work, the whole mission can be either significantly compromised or even not work at all.
04:21If a satellite doesn't have the solar panel, it's not powered, and so it doesn't work.
04:27Connectivity.
04:28If the antenna is not deployed for a communication satellite, it's not communicating.
04:34It doesn't work.
04:35And also we support some various scientific missions with various payloads
04:39that need to be deployed, locked, unlocked, and so on.
04:44So if our systems are not working, the mission consequence can be extremely high,
04:50up to losing totally the functionality of the satellite.
04:56So today, there's already a lot of satellites in orbit.
05:00Legacy solutions are working.
05:04But now we are launching more and more small satellites, smaller satellites, bigger constellations,
05:11so the scalability has now new requirements.
05:14Legacy systems, some are pyrotechnic-based, they are providing some high shock,
05:19they are one-shot, and they have some handling constraints during testing on ground,
05:24but also during launch.
05:25There are some electromechanical systems, those ones have more parts,
05:29adding weight and volume on a satellite, which is highly expensive to send in orbit.
05:35There's also some other legacy thermal devices, which have more limited thermal window,
05:42because the alloy we are producing, we really adapted it specifically for orbit use,
05:48so that it's not triggered at a temperature that can be experienced in space.
05:54For instance, in low orbit, the satellite, whether it's in the sun or in the shape,
05:59can be exposed to minus 120 degrees C to plus 120 degrees C.
06:05So it's a huge range, and it needs to operate all time.
06:09So now the new space requirements are really, we need to have something that is compact,
06:14reliable, ground-testable, and exportable for sure,
06:18because if you need to handle some exportability challenges,
06:21it's a burden for the number of satellites that are launched,
06:24and scalable needs to be produced very, very regularly.
06:30We have the smallest actuator that exists in the world.
06:34It's 4 grams, and it can generate up to 185 kilograms of mechanical power.
06:41So space is becoming really a geostrategic economy.
06:45We are moving from an exploration to infrastructure.
06:48Some history, in 1957, the first satellite was launched, so one satellite.
06:54It took almost 70 years to get a little bit more than 10,000 satellites in orbit.
07:00The plan is by 2030, in the next four to five years,
07:05there's going to be 50,000 satellites.
07:07So it's really scaling significantly quickly.
07:12Talking about technology, you cannot be at VivaTech and not talking about a little bit of technology.
07:17So what we do is we produce ourselves what's called the shape memory alloy.
07:24The shape memory alloy is moving depending on the temperature.
07:30And once the temperature increases, it takes back its form.
07:35So what you see are some examples.
07:38The power and the mechanical motion that can be created is significant compared to the size and the volume and
07:48the mass of the material.
07:51So again, various examples all illustrating the smart property of the shape memory alloy itself.
08:00Now, having the technology is good, but we also need to move from the technology into flight-ready hardware.
08:09So what we do at Nimesis, we have the whole vertical integration.
08:13So moving from producing the shape memory alloy, designing the actuators, manufacturing them, testing them,
08:21and qualifying them all for space-grade requirements.
08:26So the two strengths and what is very important is, one, our technology is very hard to copy.
08:36And two, we are able to easily scale while maintaining quality and on-time delivery requirements
08:43that are absolutely paramount for our customers.
08:47We are not only at an R&D stage.
08:50We are really already in orbit.
08:53There's already some of our actuators turning around the Earth or being sent on Mars or other FAR missions.
09:02Deliver more than 500 actuators, supported more than 10 space missions, more than 30 customers already today.
09:09We were on the Ariane 6 inaugural flight with some missions.
09:17We also supported several SpaceX missions.
09:20Our current production capability is around 40 a year.
09:25That means we have the whole production processes in place.
09:29What is really now important?
09:31So we deliver products.
09:33They are flown.
09:34Now we are ready to scale.
09:36We also are providing a whole set of products for various missions.
09:43So what matters to our customer is that it's not only selling an actuator.
09:49It really, we reduce the risk for the whole mission.
09:53Our value proposition at Nemesis is to have smaller mechanism, safer missions, and scalable space infrastructure.
10:05Our three strengths, as you saw, are the technology differentiator.
10:11We have the smart, we have proprietary and patented processes and alloys, fully vertically integrated.
10:19We are very credible, as mentioned.
10:21I will not give you the figures again.
10:24And we are ready to scale, to build those products in Europe for more sovereignty.
10:33Now, next step.
10:34So Nemesis, again, we are fully ready to scale.
10:40We convert some property of the material into actuator, doing them very simple, very reliable, very light.
10:51We are in the process of getting a funding raise.
10:56We have already secured more than 600K of business angels so far.
11:02And we will very soon officially launch a crowd equity funding.
11:07The landing page is already open.
11:09If you're interested and if you want to join our adventure and be closer to the stars, you can scan
11:17this QR code.
11:18You can register and you can get some parts of our equity.
11:27Again, just to summarize, we are ready.
11:30Technology is there, products are there, products are qualified, already available.
11:37Fruit is funding.
11:39Sorry.
11:40We will also allow to develop new products because there is a significant lever.
11:48We already have secured some France 2030 funding that will be open once we have finalized this fundraising.
11:57So time is almost gone.
12:01Alain and myself will hang around.
12:04If you have any questions following the presentation, we would be super happy to discuss and go into a little
12:11bit more details.
12:13Thanks a lot and have a nice day.
12:17Bye bye.
12:17Thank you very much.
