In this study, a novel 2-DOF flexure-based micromanipulator for applications requiring precise positioning is designed and analyzed. The micromanipulator has a bridge-type amplification mechanism and an in-plane XY micropositioning stage that make it very stiff and accurate. The findings of the mechanism's examination using finite element analysis (FEA) and simulations indicate that the workspace range is 22.2 mm and the natural frequency is 150 Hz. The study also looks into how the characteristics of the material affect the mechanism's performance. The micromanipulator is fabricated using Al 7075-T6, demonstrating a displacement amplification ratio of 9.68. Geometrical modeling is established. The result shows that a compliant parallel micromanipulator’s workspace is obtained at ± 191.81 µm× ±192.41 µm. The amplification ratio is 6.77 analytically and 6.19 computationally. The natural frequency was found to be 2134 Hz and validated analytically. The study's findings demonstrate the potential of flexure-based mechanisms for achieving precise positioning in micro-scale applications. Overall, the study shows the promise of flexure-based mechanisms for applications requiring precise positioning, representing a substantial leap in the field of micro-manipulation.
