A piezoelectric generator includes a piezoelectric ring having upper and lower plane surfaces and a first quality factor (Q-factor), a sound-wave conducting gasket acoustically coupled to the upper plane surface, a metal resonator ring positioned acoustically coupled to the conducting gasket, the metal resonator ring having a second Q-factor substantially greater than the first Q-factor, and at least one bent elastic pusher extending from a periphery of the metal resonator ring. In the generator, an external diameter of the conducting gasket is less than half of an external diameter of the metal resonator ring and the piezoelectric ring, the conducting gasket, and the metal resonator ring are concentrically aligned with respect to a rotational axis.
