The invention relates to exertion of an external pressure to a human body part (100). A proposed device includes at least two segments (S1, S2) adapted to at least partially enclose the body part (100) in a form-fitting manner. Each segment (S1, S2) contains an electroactive-material-based actuator (A1, A2), which is adapted to receive an electrical control signal (C(i)) and in response thereto adjust the actuator's (A1, A2) morphology, so as to cause the segment to apply a basic pressure profile (P) to the body part in direct response to the electrical control signal (C(i)). A pressure transition system (PTS) is located relative to the body part, the segments (S1, S2) and has such mechanical properties that the pressure transition system (PTS) is adapted to redistribute the basic pressure profiles (P1, P2) between the first and second segments (S1, S2). Specifically, a control signal (C(i)) in respect of the first segment (S1) causes the pressure transition system (PTS) to apply a first adjusted pressure profile (P1<sub |
