At IMSAS we investigate microsystems, sensors, and microfluidic devices for applications ranging from medical analysis to industrial measurement systems. In our research projects we cooperate with academia, research institutions, and industry. We have in-house facilities covering all the key technologies relevant for the realization of smart sensing and microfluidic systems. The 900 m2 clean room is operated under DIN EN ISO 9001:2008.
The Institute, which is headed by Prof. Walter Lang and Prof. Michiel Vellekoop, employs around 45 people of which 22 are working towards their PhD degree.
Group Lang: Sensoren, Sensorintegration, Neuroimplantate und Sensornetze
Group Vellekoop: Physical Chemosensors and Microfluidics
Our group investigates thermal flow sensors on solid and flexible substrates. Outstanding parameters are high temperature stability, chemical resistance and high sensitivity.
Sensor integration works on the embedding of sensors in materials. The goal is to integrate the sensor into materials in such a way that macroscopic properties, like for example the material stability, are not influenced. To reach this aim, smaller sensor elements and new material embedding techniques are necessary.
Together with cognition scientists we develop neuroimplants with the long-term objective to convey optical impressions through a cortical visual prosthesis to a blind person.
In the project “The Intelligent Container” a sensor network is developed which measures parameters of perishable goods, for example the ripeness level of fruits inside a container. Using ripeness models, the remaining shelf-life is estimated whereby the logistic process is improved.
The group investigates new approaches for miniaturized measurement systems for fluids. These systems are based on the concept of Physical Chemosensing: the determination of (bio)chemical concentrations or properties using physical measurement principles, which yields long term stability and straightforward fabrication compared to other methods. The applications range from life sciences to industrial liquids. The microfluidic chips are designed and realized in-house (IMSAS-MCB).
Our multidisciplinary research is conducted in cooperation with partners from biotechnology, hospitals, and industry. The group coordinates the Marie Curie Initial Training Network (ITN) EngCaBra in which engineering methods for the analysis of cancer and brain diseases are investigated. Current research topics are medical- and biochips, cell analysis, microfluidics and optofluidics, integrated sensors and sensor technology.
