A system for harvesting of natural power of the heart movement to be deployed entirely inside or outside human heart. The means and the method for the system deployment/extraction are provided. The system is implemented as storage “satellite” container/housing/carrier unit for piezoelectric power generator, power storage and spare volume for transported cardio stimulator devices. The piezoelectric power generator comprises embedding circuits containing the diode bridge, controller, capacitor and a number of piezo-electric elastic ceramic rods—“leaflets”, originally strained asymmetrically with accordance to the heart 3D geometry in order to obtain high energy conversion efficiency and high sensitivity to the heart movement. The innovative construction of the piezoelectric generator is applied to piezoelectric transformer based on cantilever bending vibrations.
