摘要:
The invention relates to a flexion-controllable roller (100), comprising a plurality of inner support elements (10) that can be individually controlled by valves. The valves comprise actuators (80) with a shaped body (90) that changes its expansion in at least one dimension when an electrical current is applied. Said change serves to control the valves (50).
