 Hi, I'm Dave Dewey with Pujikara Kasei out of Tokyo, Japan and we are a polymer paste maker I am with our electronics materials division and today we are exhibiting some of our newer innovations and developments in electrically conductive pastes so Where does your electrically conductive paste go? What is this for example? well, so this is our moldable material and this is printed on polycarbonate film and then thermo formed this is just something we whipped up in our lab It's just a very rough kind of idea of what you can do with this material We mounted an LED on the polycarbonate with the conductive film and and insulating overcoat So does it have to do with the formable things flexible things? Where does it go? So this is an ink a conductive ink that can be used with Formable electronics. We have a number of projects. We're working on a number of companies that are evaluating our materials to see what they can do with them and should I Yeah, sorry And in addition we are also working on some stretchable materials, which we're also just playing today Again our r&d team whipped up a nice little model Of what you can do with these materials. So this is a mock-up of a wearable electronics This one right here. Yeah, so this is just a mock-up of wearable electronics. Of course everybody's trying to make Make these work and so this is again something we whipped up in our lab just something rough That gives you an idea of how this material can be used So It's it's formed around the leg there or it's flexible or stretchable So this is a stretchable material you can bend and stretch it and then we have a couple samples here That you can take a look at and we've got laid out for visitors to try and Themselves and so this is our urethane based stretchable conductive ink Um, what's the challenge in doing something like this? Do you have to in the nano level make sure that the material is somehow able to stretch That's a very good question. Uh, so of course the stretchability is coming from the Polymer paste So of course the one challenge is making sure that you have good conductivity when the material has stretched because the conductivity comes from the physical contact between Particles of silver powder and so when you stretch the material, of course the silver Loses contact so that is one challenge with the material. It's to maintain that physical contact Within the silver powder within the silver filler When you're stretching the material Another challenge is of course is when you stretch something when you pull on something Uh, there is a memory there. It it doesn't always go back Perfectly. So there is some wear and tear there when you stretch it. It It wears out. So there's a lot of challenges with Maintaining the performance of the material as you stretch it with the number of stretches with the number of repetitions with these Expansion percentage if you're stretching 100% 200% So doesn't mean that the the device has to be robust enough to Like have a variable amounts of kind of like energy or signals going through or not really It's like a fixed one no matter what it depends on the application So, uh, we have some developers that are working on Material that uses the change in conductivity to sense the position of the stretchable material We have other developers that are Coming to us and saying no, we want consistent conductivity And so there are different Needs for different applications is uh, this is nano silver. That's right. Is this what you talk about is different something different here So these are our inks for screen printing and grab your offset printing. So this is our nano silver ink This can be printed On paper or um other substrates And then we have our this is our this is our conventional um ink uh, fuji kura kasei has been involved with printable electronics for decades And so this is one of our more conventional standard applications. This is the printed Lines for membrane switches. This is a simple keypad membrane This is a membrane for a keypad. So every keyboard cannot have one of these things inside or what? I don't know if it's every but uh a lot a lot of them do and we have uh been Making them for a decade. Sorry a long time. Yes. Uh, so a lot of keyboards use this technology And uh, we have a relatively large market share in east asia with east asian makers Oh, sorry. What what is this part here? Okay. So this is a different material. So these inks are uh, relatively higher viscosity they they Uh can be printed with a certain amount of thickness They can be screen printed. They can be metal mask printed stencil printed, but this material has a Lower viscosity and it performs more like a paint So this material is similar to technology where we have a polymer resin base with a metallic filler But unlike the inks that can be printed. This is a paint that can be sprayed onto a surface So this material has a different purpose The printable inks are to make circuitry to make circuit lead lines This material is a shield material So you apply the conductive material to a plastic substrate to a plastic casing and that gives it an elect shielding against electromagnetic interference Um, is that a huge market to to shield electronics like this or it's it's very important for electronics For example with uh automotive when you have a lot of different equipment running simultaneously, you need to Prevent interference from the different machines. Another large market is medical devices Of course medical devices need to perform. It's literally a matter of life and death So a lot of our clients are using this material for the shielding on casings or Electron uh medical devices like heart monitors and things like that that you have in a normal hospital room All right. Um, and what's going on around here? Okay Um This is our heat dissipation coding So this is a material that is designed to release heat And it can be used to improve the performance of things like heat sinks This is actually something that's being developed mostly by a different division. Uh, so it's uh Yeah, it's not something I can speak in too much detail about. Okay. Um, but it's a coding that improves the Heat dissipation of an object And this part of here Is a solar Yes, uh, so this is uh So this year at id tech x we are exhibiting with one of our partner companies Actually, they are our former parent company called fujikura and fujikura is A maker of a number of different electronic parts We've been working with them on membranes, which is for quite a long time And these are their solar panels Okay That they are that they are exhibiting this year So, um, actually this gentleman is uh from fujikura and he Can't speak in more detail about them. All right The the mic, yeah Yeah Hey, so can you introduce yourself? So, who are you? I'm uh, I'm tetsuya noda from fujikura japan Yeah, so I'm I'm in a position of serious promotion of the Dyson size solar panel As well as The sensor node which for iot Using the Dyson size solar panel So this is enough to to run the whole device? Yes. So so, uh, what's special about your solar? What what do you do? How do you compare with the solar power generator silicon type solar panel? So it can be woke Under the lower light intensity So this is not silicon. Not silicon. It's um, what is it then? So how do you? What's special? How do you how is it made differently or is it already a big market or? so so we are We are manufacturing this solar panel by using this Screen printing method type So it's printed printed electronics Um, uh, so, um, is it in mass production and big quantities or is it uh prototypes? Start launching the mass production. So this is practically In commercial level perfect All right, does it reduce the price of solar? Could be when we have a bigger model. So that could be The lower the price. All right
