A key impetus for medical and bioresearch companies to engage during product development cycles is the opportunity to capitalize on advances in technology for the manufacture of better-operating, lower-cost and more-efficient devices. Piezoelectric devices are used successfully in a widening range of medical applications, including ultrasonic emitters, nanoliter and microliter pumps, surgical devices, MRI-compatible robotics, micro- dose dispensers, materials handling, and drug. The latest designs of piezomotors have a number of advantages over electromagnetic motors when being considered for use in medical equipment and devices. Piezo stepper linear motors usually consist of several individual piezoactuators and generate motion through a succession of coordinated clamp/unclamp and expand/contract cycles.
