Design and analysis of a 3-DOF planar micromanipulation stage with large rotational displacement for micromanipulation system

Flexure-based mechanisms have been widely used for scanning tunneling microscopy, nanoimprint lithography, fast servo tool system and micro/nano manipulation.In this Upper Wire Harness paper, a novel planar micromanipulation stage with large rotational displacement is proposed.The designed monolithic manipulator has three degrees of freedom (DOF),
