Abstract
A sensor unit for use in measurements on a subject is presented. The sensor unit includes a near field electromagnetic sensor and a flexible signal transmission structure, which are integral with one another by means of at least one common continuous surface. The flexible signal transmission structure is constructed from a first layer including signal connection lines associated with sensor cells near field electromagnetic sensor and a second electrically conductive layer electrically coupled to the electrically conductive material of the sensor.
