Production Engineering

Sensorial materials can be perceived as highly complex composite materials, while sensorized structures of ever-finer granularity develop into similarly complex and highly integrated material compounds. The making of both the components and the composites and compounds themselves requires highly advanced and specifically adapted methods of production. Tasks of this kind include
  • sensor production technologies like
    • functional printing
    • photolithography
    • physical vapour deposition (PVD) and sputter processes
    • chemical vapour deposition (CVD) processes
    • optical or laser based technologies like laser ablation
  • adaptation of conventional production processes to the requirements of sensor integration.
  • special processes for manufacturing of hybrid materials and structures.
  • methods for integration of data processing and energy generation/storage facilities.
  • development and verification of process chains for realisation of advanced sensor structures and sensorial materials.
  • simulation of the above-mentioned manufacturing processes and chains.
  • real-time introduction of sensor data to production process control systems.
The department is dedicated to the development and adaptation of processes and processing sequences taking into account the specific needs and capabilities of sensorial materials and sensorised structures, as well as smart components based on these. As described in the bullet points above, the scope ranges from specialised processes needed to establish specific sensor elements via techniques for sensor or electronics integration to the simulation of different classes of production processes and process chains. An example of the latter is the simulation of casting processes during which components such as piezoelectric sensors are integrated in the final part: In this specific case, casting simulation can be used to analyse the thermal load the sensor has to withstand for various modifications of the casting process, e.g. in terms of melt temperature, melt flow rate, pressure or mould geometry.
