 So, this is a temp track by Blue Spark Technologies. Blue Spark Technologies. So, who are you? I'm John Gannon. I'm the CEO of Blue Spark Technologies. And what are you showing here? And this is temp track. Temp track is a Bluetooth wearable temperature monitor. It comes in the form of a soft, comfortable patch. So, you can peel this off and you attach it to your child. Is this a battery? It's a flexible patch. It's got a flexible battery inside, which allows you to get to that comfortable form factor. And some flexible sensors. It has a sensor in there as well. So, it has flexible electronics. What kind of sensor is going on? So, this is a temperature monitor. And it senses, records and transmits temperature data for up to 48 hours. And it transmits that to a compatible mobile device. And new... So, for example here, is it connected for real or...? Yes. Yeah. This is real. So, the John right there is my patch. So, I'm wearing a patch. And then the one below it is the one that's running in Ohio. In where? In Ohio, at our headquarters. On the wheel, baby? No. So, it's actually on the monitor here. This is in a temperature chamber back in Ohio. And we're getting real time to mind and the ability to track a temp track patch from anywhere. So, this is a flexible circuit and battery... Flexible circuit and flexible battery. How do you do that? So, the battery is made in a screen printing process. So, it's printed on a polymer substrate. So, a very flexible, safe battery. And then there's a flexible electronics in there as well that does the temperature sensing. And also stores and transmits the data. But is that lithium-ion? Something else? No, it's not. It's a traditional zinc-carbon chemistry. Which is a very safe chemistry. And how long will it last? So, this is a 48-hour device. So, it's episodic in nature.
