Magnetic position sensors are popular for industrial, automotive, aerospace, security, and
defense applications. They are cheap, reliable, rugged, and durable and they are resistant to
dust and dirt. Their disadvantage is in general low accuracy (with the exception of LVDTs,
which reached 0.1 % accuracy), slow response and sensitivity to external magnetic fields.
Gradual improvement and optimization of classical magnetic position sensors by engineering
development and applied research reached its limit. Only fundamental research can bring a
breakthrough. We will develop new design methods and new sensor principles, we will use
novel materials and devices to open the path towards substantially higher precision, speed of
response, resistance to external magnetic fields and lower power consumption.

Project Aims
a) To develop novel semi-analytic methods allowing fast parametric modelling and design of
magnetic position sensors
To design new types of magnetic position sensors using
(b) amorphous and nanocrystalline materials,
(c) fluxgate, TMR, and 3-D MEMS Hall sensors
