Emerging Technologies in Displacement Amplification of Lever and Bridge-Type Compliant Mechanism: A Review Article

This review article provides a survey of emerging technologies in displacement amplification of lever-type and bridge-type compliant mechanisms. The displacement amplification is possible with a compliant mechanism. The compliant mechanism is beneficial and efficient because of simplicity in the design and where there is accuracy, compactness, and precision is needed. We can use various categories of displacement amplification of the compliant mechanism depending upon the application. In recent years, displacement amplification of compliant mechanisms gain more attention to the researchers due to the superiority of the mechanical compliant mechanism is compared with a rigid-body mechanism. Displacement amplification compliant mechanism such as bridge types, lever type, a micro-Leverage Mechanism has briefly discussed. The performance parameters such as the principle of working, types of displacement compliant mechanism, fabrication process, operating frequency and displacement amplification ratio are found out
