ABSTRACT:
An apparatus for positioning a human subject on a surface and for transferring a subject from one surface to another. The subject is situated on the top surface of a fluid enclosure and an actuator mechanism causes local deformations of the top surface in such a manner as to create traveling waves whereby a force tangential to the top surface is exerted on the subject for moving the subject with respect to the surface. The actuator mechanism may be a motor driver and may be a plurality of linear actuators configured so as to cause local deformations of the top surface in a direction having a vertical and/or horizontal component. The linear actuators may be shape memory fibers.
