PIEZOELECTRIC GENERATOR Russian patent published in 2009 - IPC H02N2/18 

FIELD: electricity.

SUBSTANCE: piezoelectric generator is meant for emergency power supply for low-power devices - mobile telephones and electronic locks. The generator has an actuating arm, which can act on a piezoelectric element through an actuating device, made in form of a vibromechanism meant for converting movement of the actuating arm into pulsed effect on the piezoelectric element. The actuating arm can be linked to the vibromechanism through a damper spring or mechanical spring mechanism, and the vibromechanism can be self-exciting.

EFFECT: simplicity and reliability of the design; high output of electrical energy for single mechanical action on the actuating arm.
