An assembly is provided of an electro-physical transducer (10) on a flexible foil (20) with a carrier (40). The flexible foil (20) has a first main surface (22) provided with at least a first electrically conductive track (24) connected to the electro-physical transducer and opposite said first main surface a second main surface (23) facing towards the carrier. At least a first incision (25a) extends through the flexible foil alongside said at least a first electrically conductive track, therewith defining a strip shaped portion (27) of the flexible foil that carries a portion of the at least a first electrically conductive track. The at least a first electrically conductive track is electrically connected to an electrical conductor (421) of the carrier, and the flexible foil is attached to the carrier with its strip shaped portion.
