 And we hear the ID TechHack show and hi, so who are you? Yeah, my name is Alberto Escudero, I am from Spain, but I am working in Salarucan for the Leibniz Institute of New Materials. We are a research institute based on the material science that cover on one hand the very basic part of the research with our students, laboratories, doctoral thesis, but also at least half of the institute is dedicated to doing research for industries, and among the different topics that our institute carries out, we are showing here some of them connected with the printed electronics. What is this machine there? This is one machine to make transparent electrodes with electrospinning. We are able to deposit fibers onto flexible substrates and to achieve conductivity and keep the transparency. So this is one of the processing technologies we are developing at our institute. Is it a big system? It is a big system because in the so-called innovation center of our institute we can perform studies for industry and on the way to a pilot plant to make some kind of upscaling also processes for the deposition of coatings, conductive structures and many other studies related to material science. What is this? This is a flexible substrate, this is PIT foil, but this is coated or deposited with silver. This is made by photometallization. This is one low cost technique that allows us to deposit silver, conductive silver structure onto flexible substrates and we can somehow control the thickness and the dimension from centimetres nanometers to right here, to almost micrometers, so this is the fact of almost transparent. And the application of this is something like for touch panels and these kind of flexible devices. So it's high precision? High precision, yeah, because it changes the productivity, the capacity and by the different geometry of the printing you can modify this kind of things. And what is this? This is one demonstration and this based on the other type of materials that we have developed because we also developed materials and processing. This is printed with ITO ink, I'm using oxide. This is a transparent ink. So I mean you can make the connections, something like the cables here on flexible substrates with transparent structures. So it's almost transparent, you cannot see the cables here but this is something printed there to make the electrical connections and in flexible substrates. Nice. What do you show in the wall here? Here in the wall we are showing three different products as we are showing. This one is a demonstration about this electro-spinning of fibers, conductive transparent fibers onto flexible substrates, something like for example this. And the positive you can make electrodes here, transparent. On this other way we present the photometallization. This is an easy and cost effective way of depositing silver structures onto flexible substrates by the composition of different precursors and we can play with the geometry from centimeters to nanometallism. It's not centering? Sorry? It's not like photocentering, what do you call it? This is photometallization. This is very similar to the traditional concept of making photos in the past. When you have to put this into different liquids and you apply light with different masks and then in this way you can control the geometry of the position and then also the different functionalities that you can apply. And finally here we are presenting another material from the chemical point of view. This is a sinter-free ink. This is one ink that can be applied with inject printing, depositing onto different substrates and the most important property of this ink is that it's sinter-free and that means that you do not need any extra treatment to achieve the conductivity. Just by drawing at room temperature you achieve the conductivity and this is quite interesting because then you can apply this ink to different substrates like paper, a polymer foil, plastic, this kind of substrate that you cannot heat at let's say 150-200 degrees so it's also appropriate for different flexible electronics. What is this? This is one demonstration of the ink, of the sinter-free ink based on gold nanoparticles. This is just with a gold ink, just printed with a standard printer to send that gold that we can have at home and just, I mean, I just printed just some minutes ago with this kind of line and just when drawing that it takes some seconds or some minutes we just demonstrate that we achieve the conductivity. You say it's gold? It's gold, yeah, it's gold particles. We achieve the conductivity in different... Let me check here. It was working just before. This is already working, yeah, so with this part. So you don't need... And this is the printer, yeah? Is it a special printer? This is a normal printer that we can have at home. I mean, for the studies in our laboratories we use more specific printers, yeah? We can control the parameters, something like this. But this sinter-free ink is something that we can also perform here like in a normal printer at home. Are you going to print some gold? I can print for you. So this is just one card and I am just going to close this series. Print the gold. I just come here. So you put the gold cartridge in there? Exactly, here in the cartridge we fill with the gold ink. But gold is liquid. Has to be 90 degrees? No, it's a dispersion of gold nanoparticles in water. This is the key. In water? It's not in water. It's a dispersion of gold nanoparticles in water. And just printing like this with a normal printer that we can do. You will see how you can easily deposit a line of gold onto this case paper, yeah? Let's see, because it takes us some time for the... So does that mean that printing electronics can be done at home? Absolutely. I mean, if you have the conducting materials and the way of depositing, it absolutely works, yeah? Something so simple like with this printer, yeah? Sorry. Yeah, sometimes printers don't connect or something. No more battery. Oh, there's no power now? It's not power, so something was here. What is happening here? The cable somewhere. Okay. It's a demo fail. That's okay. It happens usually. No, but it makes no sense because it should work. I saw a light before. Yeah? But maybe it's because I walked in front of it. Yeah? Something like that. I'm sure it's working. So basically this comes out? This is what it comes out. Like this kind of lines, yeah? You can actually print onto different substrate. Like for example, in this case, paper. But you can also print on glass, on foil, on plastic, on silicones. It's quite versatile, yeah? So, how many people there at the Leipzig Institute? We are a medium-sized company, so it's about like 250 workers there, including PhD students, professors, scientists and technicians. I am a scientist, dedicated to doing basic research in the laboratory, but also to have contact with the different companies. And for example, staying here in this printed electronics exhibition, showing to the community of printing electronics the different materials and technologies we are showing in our, we are producing. So what's next? The next. What's happening? The next, I mean, it's just one hour more here, yeah? And then visiting other fairs and then trying to develop the material for customers and for companies and perform projects, or reset projects, yeah?
