Abstract
A vacuum gripper device including at least one suction cup including a fastener body from which there extends an elastically deformable skirt having a free annular edge for coming into contact with an object to be grasped. The suction cup includes at least one electrically conductive track secured at least to the skirt. The conductive track is made of a material that is electrically conductive and elastically deformable so as to deform together with the skirt. The device includes an electronic processor circuit that is connected electrically to two connection pads belonging to the conductive track and that is arranged to monitor an electrical property of the conductive track, which electrical property varies with the deformation of the conductive track, and to compare that property with reference data so as to anticipate a failure of the suction cup.
