technology fluidic fluxgate photodiode micro coils tracking






We are multidisciplinary research group working in the field of design, fabrication, and characterization of sensor micro-systems. The main research interests of the group are:

  • New effects and concepts for sensor and actuator devices and interface electronics
  • Design methods of the corresponding micro-systems
  • Physical and technological limits in the miniaturization of the microsystems.

Currently, the group works on the development of some novel sensor microsystems for magnetic, optical, and mechanical signals. This activity includes the following topics:

  • High accuracy CMOS integrated Hall sensors and microsystems.
  • CMOS integrated Hall sensors and microsystems for metallic cracks detetion.
  • Integrated fluxgate sensors in CMOS technology.
  • Nuclear Magnetic Resonance (NMR) and Electron Spin Resonance (ESR) CMOS integrated and non-integrated microdevices.
  • CMOS Integrated single photon detectors.

All these research activities are based on the co-development of sensors and interface electronics taking benefit of their synergies to optimize the characteristics of the final microsystems. The deep understanding of solid-state phenomena together with the use of advanced microelectronic processes open ways to novel applications. The group has a direct access to an in-house clean-room facilities as well as to external silicon foundries.

The research projects are the subject of PhD thesis,most of them run in close collaboration with industrial partners.

Hall Effect Devices (2004)
by Prof. R. S. Popovic


This is the second edition of a very popular 1991 book, describing the physics and technology of semiconductor electron devices exploiting the Hall effect. Most of the research results of our group, contributing to the state of the art in this field, are built into the book.

Microfabricated NMR-probes for the analysis of living cells
by Dr. Klaus Heinrich Ehrmann


This book describes the development of microfabricated probe heads for Nuclear Magnetic Resonance (NMR) spectroscopy of living cells. The probe heads are based on microfabricated solenoids, Helmholtz and planar coils. The cells are confined in microchannels or immobilized on the flat microprobe surface. The performance in NMR of the different microprobes is assessed in detail using simulation models and NMR experiments. Devices for on-chip placement, concentration and perfusion of living cell are tested and NMR spectra of living cells are presented.
