Zusammenfassung:	The present disclosure relates to a capacitive sensor film (50) for mounting to a body. The film comprises a dielectric backing layer (2) having, on one side, a rear major surface (2a) facing, in use, the body and, on the other side, a front major surface (2b) bearing a front conductor (4) at least partly surrounding a sensor conductor (7) which is electrically isolated against the front conductor (4) by zones where the front conductor (4) is removed and the front major surface (2b) of the backing layer (2) or another layer beneath the front conductor (4) is exposed. A guard conductor (1) is provided on at least one of the major surfaces (2a, 2b) of the backing layer, to provide an electrical shield for the sensor conductor. The guard conductor may comprise the said front conductor (4).
