Research

Our research focuses on advancing neural interfaces based on polyimide and silicone rubber in translational research. Thereby we are pursuing three approaches:

1. Improving the reliability and long-term stability of the interfaces with in vitro and in vivo testing methods, followed by in depth analysis using different approaches like FIB-SEM cross sectional imaging.

2. Implementing novel techniques to enhance assembly technologies.

3. Consideration of normative and regulatory aspects.

Methods

  •  FIB-SEM-analysis
  • Longevity tests using electrical stimulation, periodical mechanical deformation and (accelerated) aging
  • MEMS fabrication
  • Laser fabrication

Current Projects

  • Fabrication of long-term applicable polyimide based thin-film shaft electrodes (FlexBRM)
  • Moore4Medical
  • InoPro (interface section)
  • Preparation of material-tissue interfaces for further investigations
