 Hello, I'm Peter Harrop, Chairman of ID TechX. We have an interesting stand here. We're going to interview the Fraunhofer Institute and I will introduce themselves. Hello, my name is Peter Spees. I'm with Fraunhofer Institute for Integrated Circuits and we are showing here different energy harvesting systems. So we're using, for example, thermal gradient to power state-of-the-art electronics just with the heat of the human skin. Our focus are microelectronic circuits so we're developing DC-DC converters optimized for thermal harvesting systems. You can see a Bluetooth wristband which is poorly powered by the heat of the human skin. We're measuring the temperature and the acceleration in this wristband and transmitting the data to the tablet. The whole wristband is solely powered by thermal harvesting. Cool. But can you make this smaller? What's next? We are working on it. So the next version would be a lot smaller and of course we want to integrate that completely in the textiles to have fully self-powered systems. Can you power ARM Cortex M0 Plus? What's MCU? Is there an MCU? How do you make the Bluetooth work? The Bluetooth is completely powered with thermal harvesting. And the microcontroller? Yes, of course. But the microcontroller is not the problem. The problem is the power amplifier to transmit the signal. It consumes the most power. So how soon can we get this kind of stuff in all consumer electronics? This one here, a couple of years. We get a smartwatch with no need for battery. It just works by putting it on. A smartwatch is a little bit more than that one. Just the Bluetooth. The smartwatch has a lot more. It has a display. It has some more processing power. But you could have some sensors. You can have step counters. Which other sensors can be powered by skin? Step counters, temperature sensors, acceleration sensors, humidity sensors, everything.
