WebPossible Drawbacks. A piezo stage is one portion of a closed-loop nanopositioning system which includes the following three items: 1. Nanopositioner. A flexure-guided piezo stage with a feedback sensor. 2. Nanopositioning Electronics. A controller necessary to provide closed-loop operation while providing positioning signals to the stage. 3. Webflexures, the actual resulting designs are expected to deviate slightly from ideal behavior. Any approximately linear motion flexure module can be used as the building-blocks A, B, C and D. Fig. 2 presents a design based on the double parallelogram flexure module. Although simple beams are illustrated, other beam shapes may be employed as well. sdftool_flasher
