 So we're here with Light-Tricity and this is a watch with the energy harvesting, so who are you? Yes, hi, I'm Matthias, I work for Light-Tricity, so we've developed the world's highest ambient light energy harvester and so here it's shown in a watch that was just launched by Russians. So this is a watch with no battery or no? There's a battery? No, it's a mechanical watch and the energy harvesting is used to provide app-enabled functions. In a way that keeps the design, the language of the Russians watch, so it's a very particular design so you can see it's under the shutters here to provide the power when required but otherwise it's a mechanical watch. So what is the power for? It doesn't have a Bluetooth? Yes, it connects to an app on your phone to show information about the watch for time setting and other functions and so it's fully app-enabled and so that's entirely powered by energy harvesting in this watch and so obviously the key here is to be able to provide as much power from a small area as possible and that's what we enable here. So where's your energy harvester? It's sort of integrated here under the shutters in front of the watch. So this is your part right here? So that's the part exactly that's been designed to be integrated into the watch. What is it? The solar panel or what is this? It's the light energy harvesting technology exactly that's been designed to be as efficient as possible under ambient light level conditions that can be customized for challenging applications such as these watches here. And you can also power this right here? Yes, you can power other types of products using displays whether it's an MIP display, an E-ink display, a Bluetooth sensor so any product that otherwise would require rechargeable or disposable batteries. How do we power this one on? Yeah so you can sort of see here obviously so it's providing power to the memory and pixel display so that's a demonstrator but it could be obviously integrated into a watch, other type of variable display, a device, a building automation device or a retail application. Yes so we can obviously move that to a different setting here. So there's a plenty of power to power both the display, wireless transmitter, other sensors. And this could be on the wrist or no? Well it can be integrated in all sorts of different ways I mean you can see it can be conformed to integrated into a watch you can see obviously here in the example of the residence watch that it can be customized to a very high degree that's one example here. But it's just only behind this? Yes exactly it's very small but it's still providing sufficient power to power the app-enabled functions on the watch. The Bluetooth? Yes the Bluetooth obviously then the electronics that are in the watch to set the time for example. So this is a prototype? Well this is just been announced by residence earlier this year in Geneva at the watch show and so it's obviously launching in the market very soon. But wouldn't it be maybe potentially better if you had a bigger surface that you would use for your solo panel? Of course it's entirely up to the product designer to decide how they want to use the technology obviously in watches or other applications design is really important and so there's always a trade-off between maximizing the area for the solar device but then also having area for other functions and so that is what we enable. So we produce a lot of power from a small area so you don't need to use all of the available areas just for the solar device so you have space for display other functions on the watch but of course if you use more area then you can provide more power. So this is a micro-viscometer? Yes that's another application it's just showcasing what our technology can do so here it's powering a fluid sensor and then providing power for the sensing as well as the wireless connectivity to a gateway. Sensing what kind of fluid? This is for could be for oil analysis actually also for blood analysis so this is another application or another customer. You have some other watch designs over here? So this is just a demo here to show that of course it can be made in different form factors it can be semicircular to be sort of integrated under dial as perhaps this is a more traditional design where sort of just you have half of the area occupied by the dial and then the other half you would have for display but there are many different possibilities. So how soon are we going to see all these watches on the market? Oh you'll see the first of them in this year of course. That will be the first of your technology? We'll be the first in the watch application this year. And you have your technology and other things already? They are the other customers designing it into other applications. You're talking about indoor harvesting maybe this part of the phone and that part of the phone? This is actually this is more about building automation sensors so a sensor in the building that connects to your phone here you have the customers looking at all sorts of building automation applications industrial applications medical applications there's a wide range of applications where people want to get away from using this postglow recharge for batteries. Would you want to put it on the back side of your phone maybe? I think probably for these sort of large devices it's maybe not the best application because obviously you have a very large battery in the phone so it's very challenging to provide power to such a power hungry device but there are many devices which consume less power where it does make a lot of sense such as watches, IoT sensors.
