InnSenTec: measuring temperatures over a large area
Printing microelectronics on ultrathin film creates unprecedented possibilities. At Holst Centre on the High Tech Campus in Eindhoven, we’re working together with partners on promising, innovative applications. For example, we’ve developed a technology that uses sensors to measure temperatures at many different points over a large area simultaneously.
SCREEN PRINTING TECHNOLOGY IS ADEQUATE
To print sensors on film that is just 100 microns thick, it is not necessary to invest in expensive advanced equipment: current screen printing technology is adequate. As part of a Proof of Concept, experts employed by TNO printed hundreds of sensors on a sheet measuring one metre by half a metre. Rather than local, single point measurement, temperature can now be measured over a large area.
FLEXIBLE AND ULTRATHIN
The flexible ultrathin film on which the microelectronics are printed can be used in various applications. Measuring the temperature at different points on the body of a patient in a hospital bed and incorporating sensors in athletes’ clothing are two obvious examples.
Electric vehicle batteries consist of several thousand components, all of which can be monitored at cell level with this technology. A similar application could conceivably be built into laptops to detect overheating at an early stage. The technology also offers a solution in industrial processes where temperature is a crucial factor.
STABLE AND ACCURATE AT EXTREME TEMPERATURES
Sensors printed on flexible film will replace chips on printed circuit boards in equipment and machines as a means of measuring temperature. The thickness of printed circuit boards makes them less useful in devices where every tenth or hundredth of a millimetre counts.
Printed sensors have several advantages: they are potentially highly stable, they ensure high measurement accuracy and they are able to operate over a wide range of temperatures from cold to hot. This combination makes this technology unique in the world. In principle, this same technology can be used as part of an integrated printed system to measure variables other than temperature, such as humidity and pressure.
TNO is now optimising the technology and providing a Proof of Principle to show that it can be used on a larger scale. The idea is to create a spin-off company that will make the technology market ready. TNO Technology Transfer is working closely with venture builder HighTechXL at the High Tech Campus to bring this about. Talks are already underway with potential clients in the automotive and healthcare sectors.
You can read about how AI is educated in Chapter 1. How can we make clear to AI which goals we want to pursue as humans? Andhow can we ensure intelligent systems will always function in service of society?
Innovation with AI
What does that world look like in concrete terms? Using numerous examples, TNO has created a prognosis for the future in Chapter 2. Regarding construction, for example, in which AI will be used to check the quality, safety, and energy efficiency of buildings before they are actually built. Or healthcare, where robots will partly take over caregivers’ tasks and AI will be able to autonomously develop medicines.
Innovating with innovation AI
How AI will change research itself is explained in Chapter 3. For example, what role will AI be permitted to play in knowledge sharing? And what will happen when we make machines work with insurmountably large data sets?
David Deutsch on the development and application of AI
Peter Werkhoven, chief scientific officer at TNO, joins physicist, Oxford professor, and pioneer in the field of quantum computing, David Deutsch, for a virtual discussion. Deutsch set out his vision in 1997 in the book, The Fabric of Reality. Together, they talk about the significance of quantum computing for the development and application of AI. Will AI ever be able to generate ‘explained knowledge’ or learn about ethics from humans?
Rob de Wijk on the rise of AI in geopolitical context
Anne Fleur van Veenstra, director of science at TNO’s SA&P unit, interviews Rob de Wijk, emeritus professor of international relations in Leiden and founder of The Hague Centre for Strategic Studies. Rob is also a much sought-after expert who appears on radio and television programmes. What does the rise of AI mean geopolitically and in armed conflicts?
