Abstract
Device with isotropic planar compliance comprising a floating body (2) positioned between a first (3) and second frame (4), said floating body having an extended portion (21) protruding through the first frame, at least a row of caged balls (5) supporting the floating body, at least one elastic element (6) positioned over the extended portion of the floating body, compressed between and connecting the floating body and the first frame. Said caged balls allow the at least one elastic element to laterally deform, so that their axis bends, while the ends of said at least one elastic element lay on two parallel planes, which remain at constant distance while sliding one with respect to the other. The device comprises also at least one displacement sensor (10), for measuring the displacement of the floating body with respect to the first or second frame.
