The discussion focused on our core areas: from cleanroom infrastructure and quality assurance to the importance of sustainability and safety in highly sensitive production processes. The editorial team was impressed by the combination of science, technical excellence, and practical implementation in the everyday work of our facilities. Particular emphasis was placed on our continuous investment in modern technologies, which enables us to implement complex research projects efficiently and reliably. We value the cooperative partnership with the media and the opportunity to create transparency about our working methods. We would like to express our sincere thanks to the entire up2date team—for their interest, technical expertise, and valuable insights.

The second day was dedicated to the world of microtechnology and started with a lecture by Prof. Dr.-Ing. Björn Lüssem about cleanroom technology. Right after lunch, the theory was put into practice with a workshop inside the IMSAS cleanroom, guided by Melanie Kirsch, where we gained hands-on experience in photolithography and wet-chemical structuring of metallic thin films on a wafer. To demonstrate how small micrometer scale is, we examined structures fabricated using 2-photon polymerization first with the bare eye, then with the incident light microscope and finally revealed the structures using the scanning electron microscope (SEM), with all steps very well explained and carried out by Dipl.-Ing. Eva-Maria Meyer.

In the poster, Nicole describes how she realized funnel inlets to nanochannels by a grey-scale lithography method. The funnel inlet should allow DNA molecules to easily enter the nanochannel in which they can be analyzed. Nicole is employed at the Bosch Research Campus in Renningen, Germany in the group of Dr. Martina Hübner, and a doctoral candidate at IMSAS – Uni Bremen in the research group of Prof. Michael Vellekoop. We congratulate Nicole Hintz and the whole team with the award!

The correlation between mold exposure and to some extent severe illnesses has been proven by several studies. Up to now, there is no reliable way to continuously quantify mold contamination. Because of the extensive and expensive laboratory-based analysis, it is often not determined at all or only sporadically. The aim of this research and development project is the realization of an automated sensor system for continuous measurement of mold contamination within industrial bio filter systems. For this, a novel micro-reactor-array will be designed, which allows autonomous cultivation and detection of mold spores. The project is being funded by <abbr title="Arbeitsgemeinschaft industrieller Forschungsvereinigungen „Otto von Guericke“ e.V.">AIF</abbr>/<abbr title="Central Innovation Programme for small and medium-sized enterprises (SMEs)">ZIM</abbr> and runs for 2.5 years.

Björn Lüssem was Associate Professor at Kent State University in Kent, Ohio, US. The area of his research covers design and technology of flexible organic devices (e. g. organic electrochemical transistors and sensors) and processes to integrate these devices into larger sensor systems. We wish him a&nbsp; lot of success in Bremen!

Sensor information will be used to monitor drying equipment after water-induced damages. Flooding repairs usually take several weeks and require large amounts of energy. Multiple checks by a technician might be necessary to determine when a sufficient drying state is achieved and the equipment can be switched off.

Our vision is a fundamentally new sensor concept for in-line monitoring of liquids in cylindrical structures like pipes (chemistry) or vessels (medicine). The DFG and ANR funded project brings together research groups from the Université Pierre et Marie Curie in Paris, Université de Lille, Otto-von-Guericke-University Magdeburg, and University of Bremen, with the Kick-Off meeting held on 16.01.2019 in Bremen. &nbsp; Content content-238259 Wed, 04 Mar 2026 23:43:54 +0100 November 2018 https://www.uni-bremen.de/en/imsas/news#c238259 AT the IAV Talent Innovation Day in Berlin the IAV Talent Award "Future Mobility" was awarded&nbsp; to the The Projektarbeit of Marcel Reimers&nbsp; „Temperature Monitoring of Lithium-Ion Cells with Printed Sensors for Automotive Battery Packs”&nbsp; in the category "Projekt".&nbsp; 01.11.2018&nbsp;. &nbsp; &nbsp; Content content-238262 Wed, 04 Mar 2026 19:22:16 +0100 November 2017 https://www.uni-bremen.de/en/imsas/news#c238262 In many applications it is necessary to measure not only the magnitude, but also the angle of the air-velocity, e.g. for capturing the flow field in gaps or at surfaces. So far, two separate sensor chips were required to construct a 2-dimensional anemometer. The new IMSAS chip integrates 4 thermopiles placed with a small offset in ±x and ±y direction, close to a heater. Magnitude and angle can be calculated by the x and y difference signals.&nbsp; The first samples were processed in our clean room and put into service. The required chip area was reduced to 2mm by 2mm, i.e. only 60% of the initial 1-dimensional chip design. Now, only one square 2D chip is necessary instead of two 1D chips. In total, the required chip area was thereby reduced to one third.&nbsp; The new chip also enables more efficient housing and PCB designs. The sensor element can now be placed exactly in the center of the housing, resulting in an equal sensitivity in all four directions.&nbsp; The first test in our wind tunnel has shown that the new chip has a higher sensitivity at low velocities.&nbsp; Nine Wireless Anemometers, equipped with the new 2D chip, were installed in a cold storage warehouse for apples during a field test in November 2017. &nbsp; Content
