The Fraunhofer Institute for Photonics Microsystems (IPMS) is involved in an interdisciplinary research project called 'InSeKT' (Development of Intelligent Sensor Edge Technologies). This project, carried out by the Technical University of Wildau, the Leibniz Institute for Innovative Microelectronics (IHP), and the Fraunhofer IPMS, aims to integrate artificial intelligence (AI) more effectively at the 'edges' of IT networks. The project focuses on miniaturized sensor structures and the integration of electronic components, with the goal of enabling complex calculations directly at the data source, such as at the sensor itself.

Current data processing with AI often occurs through central cloud computing solutions, leading to data transfer over large distances and potential data leaks. The project addresses this by promoting decentralized data processing for improved data security and real-time system capabilities.

The project covers various areas, including gas analysis using ion mobility spectrometers (IMS), data-supported evaluation of photodetectors for the near-infrared wavelength range, and the adapted use of capacitive microelectromechanical ultrasonic transducers (CMUTs) for improved imaging. The generated data will be used to train Edge-KI systems for fast and accurate data processing.

➀ Regina Luig developed a method for indirect temperature monitoring of the rotor magnets in electric motors during her bachelor's thesis at Hochschule Coburg.

➁ Instead of temperature, she measures changes in the magnetic field, which weaken as the motor heats up.

➂ This innovative approach helps prevent overheating and reduces the need for rare earth materials, thus contributing to the sustainability of electric motors.

➀ The Fraunhofer Institute for Photonics Microsystems (IPMS) has achieved a milestone in chemical liquid analysis with the miniaturization of electronics required for ion-sensitive field-effect transistors (ISFETs).;

The researchers at Fraunhofer IZM have developed a glue-free laser welding process for coupling photonic integrated circuits (PICs) with optical fibers, which can also be used in cryogenic environments of up to four Kelvin, equivalent to -269.15°C. This technology offers a more reliable, faster, and cheaper fiber-PIC coupling through a direct quartz-quartz connection, revolutionizing applications in quantum technology.

Low-temperature environments are essential for observing quantum effects, which can greatly improve human quality of life, such as in big data processing for personalized medicine and hospital information management. The development of cryogenic systems for quantum computing is currently being actively promoted. Quantum technological systems with implemented PIC-based modules offer a compact solution for secure communication and networking in quantum computing. Reliable fiber optic connections are, however, a fundamental requirement for such photonic quantum systems.

The focus of the QWeld research project is on realizing this connection technology for applications in cryogenic environments. Standard CMOS-manufactured PICs with a silicon dioxide (SiO2) coating are used, which is necessary for glass-glass laser welding. A vertical coupling of the fiber with the PIC, typically with a specific angle, is a special feature. The laser meets the contact point between the PIC and the fiber on both sides during welding and creates a material-bonding connection within seconds. This manufacturing process offers significant time savings.

➀ A German-Danish research group is working on a novel freshness sensor for meat and fish in the PRECISE project. The researchers aim to determine the shelf life of meat and fish using a new 'Electronic Nose' and thus predict precisely to prevent tons of food from being wasted. Experts from TH Lübeck are part of the research project and are currently testing and optimizing the freshness sensor at the CoSA Competence Center. The researchers are funded with 1.885.263 Euro by the EU Interreg Germany-Denmark program until March 31, 2026.

➁ The current methods to determine if meat or fish is still edible involve trained personnel using their nose to check for freshness and expensive, time-consuming microbiological analyses that take days to produce results. What is lacking is a technical solution that can accurately and quickly determine and predict how long meat and fish can be stored.

➂ The project aims to save up to 25,000 tons of meat and fish from waste. The team, led by Roana de Oliveira Hansen from SDU, brings experience in sensor development. The CoSA team at TH Lübeck contributes to the prediction of shelf life. The Fraunhofer ISIT in Itzehoe produces the piezoelectric cantilever sensors, while the Danish startup AmiNIC brings expertise in prototyping and software updates based on partner data.
