Flexible Electronic Systems and Embedded Epidermal Devices

Flexible Electronic Systems utilize polymers and other flexible or strechable materials to form wearable and conformable devices. These system are often composed of various flexible, bendable but also small ridgid components, such as electrodes, transducers, energy storage units, transistors and complete IC's.

These designs allow for comfortable wear, as they can be positioned closely to or even attached to the human body (as epidermal devices). In addition, and through the integration of digital electronic components, these devices can perform a wide range of complex functions, such as continuous monitoring and modulation of physiological signals or communication with other devices.

However, the development of such systems faces a number of challenges. These include not only material properties per se (e.g., flexibility, stretchability, or biocompatibility), but also reliability issues due to bending and mechanical stress on the entire hardware and signal stack, as well as interface challenges at all levels of integration. In addition, advanced and specialized manufacturing techniques are required for their fabrication.

Our Activities

Our research aims at improving the interconnectivity and processing reliability of digital circuits on flexible, stretchable substrates. This brings hardware intelligence ever closer to the skin surface. Additionally, we develop smart embedded solutions to optimize manufacturing processes.

All projects are annotated with one or more possible project types (M/S/B/G) and a number of students (1 to 3).

  • M: Master's thesis: 26 weeks full-time (6 months) for one student only
  • S: Semester project: 14 weeks half-time (1 semester lecture period) or 7 weeks full-time for 1-3 students
  • B: Bachelor's thesis: 14 weeks half-time (1 semester lecture period) for one student only
  • G: Group project: 14 weeks part-time (1 semester lecture period) for 2-3 students

Usually, these are merely suggestions from our side; proposals can often be reformulated to fit students' needs.
