ABSTRACT:
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.
