| Summary: | Magnetic field detection has been widely accepted in
many applications such as military systems, outer space
exploration and even in medical diagnosis and treatment. Low
magnetic field detection is particularly important in tracking
of magnetic markers in digestive tracks or blood vessels. The
presence of magnetic fields’ strength and direction can be
detected by a device known as magnetometer. A magnetometer
that is durable, room temperature operation and having nonmovable
components is chooses for this project. Traditional
magnetometer tends to be bulky that hinders its inclusion into
micro-scaled environment. This concern has brought the
magnetometer into the trend of device miniaturization.
Miniaturized magnetometer are usually fabricated using
conventional microfabrication method particularly surface
micromachining in which micro structures are built level by
level starting from the surface of substrates upwards until
completion of final structure. Besides time consuming, this
method requires many consecutive steps in fabrication process
and careful alignment of patterns on every layer which
increase the complexity. The issue of miniaturization and
complexity of conventional fabrication process has lead to this
investigative research. The main objective of this research is to
investigate and analyze the best and reliable micro coil for
search coil magnetometer. Simulations and analysis for microscaled
coil that is capable of detecting low magnetic field are
done. The expected work include investigation on possible
magnetometer of detecting low magnetic field, designing micro
scale magnetometer, complete device fabrication processes,
testing and characterization of the fabricated prototype device.
Based on the results of simulation, a search coil magnetometer
of 60m thickness with spacing of 60m and 30 turns was
designed. |
