1. An energy harvesting mechanism for a cardiac pacemaker, the mechanism comprising:

  • a deformable energy converter positionable inside a human body to generate electric power signals in response to a bio-kinetic event of the human body, a portion of the energy converter being at least partially formed by a material which directly converts mechanical deformation of the converter caused by the bio-kinetic event into the electric power signals, the energy converter having a stiffness/flexibility which varies over a length of the energy converter so that the energy converter provides a resonant frequency within a normal physiological range of the bio-kinetic event when the converter is deformed; and

    a signal path component structured to enable the power signals to be carried from the energy converter to the cardiac pacemaker.
