A method and an arrangement to monitor localization, movement, and
properties of an object, such as human body. An excitation signal is
connected to a first division of selected conductors of a transducer
which includes a distribution of conductors such as a matrix. A first
signal including information about coupling impedance between a first and
a second selected division of conductors is derived from a coupling of
the excitation signal between the first and the second selected divisions
of conductors of said transducer. The object is monitored by studying
changes of the coupling impedance caused by the object to be monitored
during subsequent repeated cycles of the above mentioned steps.
