Long-Stroke Nanopositioning Stage Driven by Piezoelectric Motor [PDF]
Journal of Sensors, 2014 This paper reported a biaxial nanopositioning stage single-driven by piezoelectric motor. The employed piezoelectric motor can perform two different driving modes, namely, AC drive mode to drive in long-stroke and at high-speed and DC scanning mode with the high-resolution of several nanometers, which satisfies the requirements of both long-stroke and ...
