The invention relates to a textile fabric to be placed onto the skin and/or a wound of a patient, comprising a top side facing away from the skin and an underside which faces the skin and on which the textile fabric has a moisture-impermeable barrier 14, wherein the textile fabric is formed from non-conductive warp threads and non-conductive weft threads and from conductive warp threads and conductive weft threads which are arranged such that an electrically conductive structure 5 consisting of conductive warp and/or weft threads K, S is formed in the textile fabric. The invention also relates to a transdermal patch for applying an active substance, contained in an active substance reservoir 17, over the patient's skin, comprising a textile fabric of this type, and to an assembly consisting of a transdermal patch and an evaluation unit 20 for detecting the amount of active substance in the active substance reservoir in the transdermal patch. The preferred embodiment of the invention provides that measured values are acquired using a first and second sensor 6, 7, which are formed by conductive warp and/or weft threads K, S. The first sensor 6 is arranged in the region of a first opening 18 and the second sensor 7 is arranged in the region of a second opening 19 in the moisture-impermeable barrier 14. One of the two sensors 6, 7 is a moisture sensor that allows moisture, in particular perspiration, to be measured on the patient's skin, whilst the other sensor 7, 6 can be used to detect any given state or any given variable. By measuring the moisture, it is possible to compensate for the effect of perspiration from the patient's skin on the detection of said state or variable, for example the amount of active substance in a transdermal patch.
