The invention relates to an apparatus (1) for impedance measurement of an external substance, said apparatus comprising a plurality of resonant circuits with respective coil elements (3a, 3b, 3c, 3d) and respective capacitive elements (5a, 5b, 5c, 5d), said resonant circuits operating at different resonant frequencies. The signals (S1, S2, S3, S4) from the resonant circuits are detected by an ampere meter (6). The power loss experienced by the resonant circuits due to an electromagnetic interaction with a conductive body is reflected in a change in the magnitude of respective signals. By detecting the signal (S1, S2, S3 or S4), the power loss by the resonant circuit is determined. The resonant circuit is preferably integrated into an insulating fabric carrier (2). The invention further relates to a vital sign measurement system and a method of enabling an impedance measurement.
