A transducer assembly including a support terminal and at least one probe extending from the support terminal is adapted to enable a transducer to penetrate and slide through patches of hair covering a subject area of a person. The probe includes at least one leg structure supporting a transducer disposed at the distal end of the leg structure for sensing or stimulating the state of a particular property of a selected subject area when the transducer is applied by the leg structure to the selected subject area. The leg structure is so disposed in relation to the support terminal as to be disposed at a non-perpendicular angle to the subject area when the transducer assembly is applied to the selected subject area. The leg structure is adapted to flex when the transducer is applied under pressure to the selected subject area to thereby cause the transducer to slide on the subject area.
