Flexible Sensors for Health

Understanding or controlling complex systems is only feasible with the necessary data basis. Increas-ingly sophisticated sensors are needed to measure physiologically relevant quantities. Acquisition of such data on or near living organisms imposes special challenges. The sensor must work reliably under complex and variable conditions. Most sensors used today are bulky and need complex connectivity to extract the sensor information.


In future, such sensors will be wearable, flexible and compatible with organic matter. To make the next steps towards flexible (bio-)sensors one has to solve a number of complex problems, which are inter-disciplinary in nature. Therefore, expertise from materials science, materials processing, life sciences and biotechnology is required to generate innovative solutions.
Structured films increase the specific functional surface and thus can enhance functionality and sensor sensitivity
Challenges for flexible (bio-)sensors are:
  • Novel sensing materials (e.g. functionalized polymers, ceramics etc.)
  • Novel forms (e.g. processing)
  • Highly structured sensing films (e.g. specific functional surface)
  • Sensing surfaces (e.g. specific affinity chemistry)
  • Sensing techniques (e.g. cheap, portable, reliable, etc.)
  • Simple connectivity (e.g. electrical, optical, etc.)
  • Long-term host compatibility (e.g. biocompatibility)
Sensors on the basis of polymer optical fibers or functional textiles. Modification of the fiber cladding with sensitive moieties, which react to their environment. Detection by change in light intensity and/or wavelength of gases, liquids, biomolecules, and microorganisms.

Our approach:

  • We address these challenges by an interdisciplinary network.
  • We are interested in both fundamental and applied research.
  • We are competent to collaborate with academic and research institutions and industrial partners alike.
