In the current study, harvested energy from a piezoelectric device which runs by movements of body
muscles was analyzed by finite element method. A piezoelectric stack, which is transducer of
mechanical energy to electrical energy, could be placed inside of body and transforms displacement
energy of ribs movement to electrical energy. This electrical energy could be applied in treatment of
internal injuries of body, provide required energy for heart batteries used in pacemakers.
Using finite element software, Abaquse with its novel capabilities in the piezoelectric field, makes this
kind of analysis available. After designing and creation of finite element model of the piezoelectric
stack in the software, the harmonic displacements of ribs which generated by breathing process are
applied as boundary conditions to the finite element model. Then by performing harmonic analyses, the
produced voltage and electrical energy are extracted from output results. Finally, The results are
sentenced based on physiologic condition of body and produced voltage and electrical energy. The
results show that the piezoelectric stack can produce enough electrical energy for low power
consuming devices such as pacemaker.
