    Oxygen saturation in the blood that is either too low or too high can cause lasting physical harm or even death. This is why patients’ oxygen concentrations are monitored continuously in both intensive care and trauma units. However, the pulse oximeters typically clipped onto a patient’s fingertip for this purpose can be unreliable. Researchers at the Fraunhofer Institute for Physical Measurement Techniques IPM have developed a fluorescence-based sensor that measures the oxygen content of people’s breath directly and in real time in an effort to provide accurate figures in the future. The sensor determines the O2 concentration in the respiratory gas according to the principle of fluorescence quenching, which allows conclusions to be drawn about the oxygen saturation in the blood.

    In the production of printed circuit boards (PCBs), micrometer-diameter vias – known as microvias – are drilled through multilayer PCBs. Lasers can drill through these structures with high throughput and micrometer precision. A measurement technique based on laser-induced breakdown spectroscopy (LIBS) is set to check the quality of the holes inline and control the process.

    An optical inspection system inspects the geometrical dimensional accuracy and surface quality of cold-formed components during production for the first time – to within a few hundredths of a millimeter. This technology allows components with low manufacturing tolerances to be produced by forming rather than energy-intensive machining. Fraunhofer IPM will be presenting the demonstrator at HANNOVER MESSE.

    Building inspection benefits from laser-based measuring systems providing quick and accurate digital measurement data. In the future, lasers will help detect subsurface damage, too. Up until now, the only way of detecting hidden defects was the so-called impact hammer test.

    Brain researchers have high hopes for quantum sensors to provide deeper insights into the brain one day. This is also a research focus of Fraunhofer IPM. Two events in December provided an insight into the topic: Professor Svenja Knappe delivered a public Carl-Zeiss-Humboldt Lecture to show how quantum sensor technology could advance brain diagnostics and therapy, and an experts’ workshop explored the topic of optically pumped magnetometers for magnetoencephalography.

    Researchers at Fraunhofer IPM and their partners have now shown that logs and trunk sections can be identified based on the structure of the cut surfaces. As part of the DiGeBaSt research project, the team developed a marker-free and tamper-proof optical method that allows up to 100 percent recognition – even under the rough environment conditions of the timber industry.

    Converting digital building data into 2D plans or 3D models quickly and easily – that is the business model of bimeto GmbH. The Freiburg-based start-up, which was spun off from Fraunhofer IPM, offers solutions to digitize and automate construction planning and thus make it more efficient. A few months after entering the market, the company employs four people and is already cooperating closely with partners from industry.
