Design And Study Of Piezoelectric Energy Harvesting Cantilever From Human Body

Piezoelectric energy harvesting from vibrations of the human body has become an interesting topic to supply medical devices. The output power of the piezoelectric energy harvesting system depends on the geometry of the device and the material used.The paper presents a study about piezoelectric system which converts the human breathing movement into electrical energy. We propose a new parametric study of piezoelectric cantilever based on a study of the dimensions' influence of the device and the material used on the optimization of the recovered energy. We obtain simulations for different dimensions based on the finite element method (FEM).
