Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mechanical Design and Production Summary: A symmetric five-bar compliant mechanism is introduced to amplify the input persistent vibration for energy harvesting. Displacements in the compliant mechanism are due to deflections in its flexure hinges. The mechanism is analyzed using a pseudo-rigid-body-model and an elastic model to calculate displacement amplification ratio and stresses within hinges. Both models have been validated experimentally and numerically using a finite element model. The effects of the mechanism dimensions and hinges stiffness on displacement amplification and stresses were investigated. Experiments indicate the success of proposed mechanism in amplifying low frequency harmonic excitation inputs and harvesting of power
