In this work, a new single-axis flexure-based micropositioning stage is proposed, which is guided by a skewed double compound parallelogram. This skewed double compound parallelogram gives a function of guide mechanism as well as a function of displacement amplifier. Using this self-guided amplifying mechanism, a long-range motion can be achieved within a compact size. For an example, we designed a millimeter-range flexure-based stage using a stack-type piezo-actuator. Leaf-springs are utilized for hinges, which can be monolithically machined by electric discharge machining.
