Study on the design of fully compliant motion amplification mechanisms in actuation systems for micromanipulators

The fully compliant mechanism characterizes that all kinematic pairs are designed as flexure hinges to play the same role as conventional joints, and may achieve a very high positioning accuracy as well as to decrease the manufacturing and assembly costs. It provides a perfect alternative for the design of the motion amplification mechanism in actuation systems for micromanipulation applications. The design issues on the fully motion amplifier are systematically discussed: based on the enumeration for the typical structures of the fully compliant motion amplification mechanisms and comprehensive considerations for their structural design, several high-accuracy and large-stroke mechanisms for amplifying the motion have been developed.
