Due to the versatility of the Bezier curves, the force-displacement relations of the mechanisms can be designed to meet the demand. The design of the mechanism is based on an optimization design approach. Force-displacement curves are obtained by finite element method. Prototypes are fabricated by a milling machine. The experimental force-displacement curve agrees with the design. The Bezier curved beam design has a high potential in design of beam type compliant mechanisms to meet various design requirement.
