Finite element simulation of a piezo-electric generator (PEG) of a cantilever type with an active termination is considered. Finite element modeling was performed in the Ansys complex. The generator has a bimorphic arrangement of piezoelectric elements. A special feature of PEG is that the generator has two types of piezoelements: (1) elements located on the substrate in the form of a bimorph and (2) cylindrical piezoelements, which fix the cantilever plate. PEG can be used as a device for
