Abstract
The proposed device includes two segments adapted to enclose a body part in a form-fitting manner. Each segment contains an electroactive-material-based actuator, which is adapted to receive an electrical control signal and in response thereto adjust the actuator's morphology, so as to cause the segment to apply a basic pressure profile to the body part. A pressure transition is adapted to redistribute the basic pressure profiles between the first and second segments. A control signal in respect of the first segment causes the pressure transition system to apply a first adjusted pressure profile to at least part of the second portion of the body part, and vice versa, a control signal in respect of the second segment causes the pressure transition system to apply a second adjusted pressure profile to at least a part of the first portion of the body part.
