The invention relates to an apparatus according to the present invention for generating the motion of a tool, in particular for the work on biological cell material, in particular for performing ICSI, comprises at least one actuator element, an actuated member, a motion section, at which can be arranged a tool and which is linked to the actuated member, the actuated member being elastically deformable, the actuator element being linked to the actuated member such that an actuation by the actuator element elastically deforms the actuated member by a distance, which corresponds to a length change of the actuated member, wherein said length change causes said motion of the motion section. Further, a corresponding method for generating a tool motion is provided.
