➀ Researchers from Fraunhofer have developed sensor systems and measuring equipment to detect leaks in hydrogen lines and tanks.

➁ The ultrasonic sensor utilizes the photoacoustic effect to detect hydrogen leaks and can also identify small traces of other substances.

➂ A laser spectrometer and Raman spectroscopy are used for remote detection of ammonia and selective detection of hydrogen respectively.

➀ Researchers from Nottingham Trent University, Helmholtz-Zentrum Dresden-Rossendorf, and Free University of Bozen-Bolzano have developed washable, durable electronic textiles that can sense magnetic fields.

➁ These textiles can be used in clothing and other fabrics, functioning reliably underwater and in various weather conditions.

➂ The technology allows users to interact with devices using a ring or glove containing a small magnet, reducing wear and tear compared to traditional tactile sensors.

➀ The INM – Leibniz-Institut für Neue Materialien presents functional inks and coatings at the LOPEC in Munich, tailored for specific applications.

➁ The inks are designed for flexibility, heat sensitivity, and conductivity, suitable for various applications including wearable devices and smart buildings.

➂ The INM showcases its innovations at stand B0.610, including functional surfaces, transparent heating structures, and satellite communication components.

➀ Researchers at Aalto University have developed a miniaturized spectral sensor small enough to fit into smartphones or wearables.

➁ The sensor measures 5 micrometres by 5 micrometres, capable of distinguishing thousands of colors with high accuracy.

➂ Unlike traditional spectral sensors, this new sensor uses electrical responses to light, reducing size and cost, and making integration into everyday devices easier.
