Voltcore will present its next-generation conductive polymer filaments and heating fabrics, designed to deliver fast, homogeneous and energy-efficient surface heating. During the session, we will demonstrate how our ultra-thin and flexible materials can be integrated into seats, interior surfaces, wearables, food delivery systems and industrial applications, replacing traditional copper-based heating with lighter, more recyclable and easier-to-integrate solutions.

00:02Hello Fabrice!
00:04Thank you Eric. How are you? Very good. Good. The four is yours.
00:08Thank you very much. Hi everyone.
00:11So Fabrice from Voltcore. Today
00:15around 40% of CO2 emissions are coming from
00:20heating technologies. And surface heating
00:23has not been optimized. It's still working on last century
00:27technologies using snake shape copper
00:31wires that are slow to heat, that have very
00:35low energy efficiency, that are rigid or bulky
00:39and which does not allow to have a very lightweight
00:43solution, very effective solution. Moreover
00:47copper is a problem in itself. There is a dramatic
00:51growth of copper demand which is driven by
00:55the increase of electrification
00:57so electrical car,
00:59data centers, which is driving
01:01the price of copper higher and higher
01:03which is as well making
01:05copper less and less sustainable.
01:08We need to dig for
01:09more and more low
01:11quality ore. It takes
01:13higher and higher energy to extract it
01:15and therefore copper is becoming more
01:17and more CO2 intensive
01:19material.
01:20Therefore, at Voltcore, we decided
01:24to work on changing
01:28the basis of surface heating
01:30from that last century technology
01:32to something which is more modern
01:34and more adequate with the
01:36expectations of today.
01:38And to do that, we start from
01:40commodity materials
01:42that are easily found
01:44like any polymer, any basic polymer
01:47in which we infuse some carbon nanotubes.
01:50So those are very long tubes of carbon
01:54at the nanometric scale,
01:57a million times smaller than a millimeter.
01:59And by doing so, we create compounds
02:02that are now conductive.
02:03So we move from a non-conductive polymer
02:07into a conductive polymer.
02:09And when we have that polymer,
02:10we can subsequently generate fibers.
02:13So those fibers are like a quarter of a millimeter,
02:17so 250 micron.
02:19It's slightly thicker than my hair
02:21of what remains of them.
02:23And that fibers can then later on
02:26be weaved into meshes,
02:29like you can see here.
02:31So very lightweight.
02:32We are talking about something like
02:3540, 50 grams per square meter.
02:37So very lightweight, very flexible fabric
02:40that has in its core
02:43those conductive fibers
02:45that are as well heating fibers.
02:47We can as well make a bit thicker
02:49fabrics like this one
02:52which contains on all those
02:54black horizontal line
02:56or heating filaments.
02:58Now when you apply electricity
03:00on those fibers,
03:03on those fabrics,
03:05it will create heat.
03:07It will start to heat up
03:09the application that you are having.
03:13So the beauty of that technology
03:19compared to the historical copper wire
03:21is that we can position ourselves
03:24directly under the surface
03:26that needs to be heated.
03:28So if you think about your car seat,
03:31your car seat today,
03:32in your heated car seat,
03:34you have those historical copper wire
03:36that are deep in the seat
03:38and that are using a lot of the electricity,
03:41the energy of the car
03:42or the battery
03:43in order to heat up the surface
03:45because a lot of the heat
03:46is dissipated in the seat itself.
03:50Now before technology,
03:52instead of being at 5 to 13 millimeters
03:54from your skin,
03:55instead of losing a lot of the energy
03:57by heating the seat,
03:58we are closer to your skin,
04:00closer to your body
04:01and therefore we can save a lot of energy
04:03to heat you up.
04:04And that's what we call the second skin.
04:07This ability to be very, very close
04:09to the surface that needs to be heated,
04:11the place where you are standing.
04:15Now the advantage driven
04:17by that kind of positioning
04:18and by that kind of technology
04:20compared to the copper
04:21is that we will be using
04:23two times less energy
04:25to deliver the same sensations,
04:28the same comfort feeling.
04:29we will be having
04:31very homogenous temperature.
04:33So when you look at
04:34from a low temperature point
04:36or high temperature point
04:38in the same heating mat,
04:39we have less than 4-5 degrees
04:41of difference between
04:42different parts of the fabric
04:44which is much more homogenous
04:46than historical copper-based solutions.
04:50And we heat much faster.
04:52We heat 30 to 40% faster
04:54than a copper system.
04:57Obviously,
04:57we benefit as well
04:59of the fact that being synthetic.
05:01So the fact of being synthetic
05:02and not metallic
05:03means that all fabric is very light.
05:05So it's significantly lighter
05:07than classical heating mats
05:09that you would have in the industry.
05:11And by the fact that we can fine-tune
05:15the recipes that we are using
05:17and the quantities of filaments
05:19we are using,
05:19we can play with different voltage.
05:22So we can plug those heating fabrics
05:25directly to your phone battery
05:27or we can plug it to your 230 volts at home.
05:30So we can fine-tune the technology
05:32from 5 volts to 230 volts
05:35depending on the source of electricity
05:38that you have around you
05:39when you need it.
05:42That comes as well with the fact
05:43that we use only one material.
05:47So when you look at the fabric
05:48it looks like
05:49we have multiple kinds of filaments
05:50but at the end of the day
05:52all of them
05:53are based on the same material.
05:54So we would be using
05:55only polypropylene
05:57or only nylon
05:58or only polyesters
06:00for the black filaments,
06:02the white filaments
06:02and as well the conductive yarn.
06:04So at the end of life
06:06we can easily recycle the material
06:08because we don't need to separate
06:09the copper wire
06:10from the rest of your fabric.
06:13So it's a very easy to recycle material.
06:17Now that triggers the ability
06:20to be integrated into many different applications.
06:24We are integrated into what we call
06:26the comfort cocoon in the automotive.
06:28So this is basically covering all the surfaces
06:32that are around you in your car
06:33to heat you up
06:35instead of using the ventilation
06:36to reduce the consumption of your battery
06:39in your electrical car.
06:42We can as well be used into things
06:45that are even closer to you
06:46which are all heated apparel.
06:48It can be heated jacket for outdoor activities.
06:51It can be heated jacket for workers.
06:53It can be as well medical devices
06:55like heated belt
06:58that would help on some disease.
07:02And finally,
07:02we have as well
07:03the ability to be integrated
07:05in delivery applications
07:08like for example
07:09the hot food delivery
07:10where we can connect
07:12the heated box
07:13with the platform of the rider.
07:17So when the rider goes to pick up an order
07:19the box is switching on.
07:21When he is delivering the order
07:23the box is switching off.
07:24If he goes to a sushi place
07:26of course the box is not heating up.
07:28So we can fine tune
07:29the way the box is automatically heating
07:31and shutting down
07:32depending on the final application.
07:34So that's what we do.
07:37We are obviously very eager
07:38to work with any companies
07:40which is interested in developing
07:42a heated application
07:43in lightweight
07:44in a very flexible fabric way.
07:47And as well in order
07:48to drive applications
07:49that are much more sustainable
07:51than the existing application.
07:53So with that
