SELF POWER GENERATOR USING PZT ELEMENT WITHOUT EXTERNAL POWER SUPPLYING

摘要

PURPOSE: A non-power piezoelectric generation system is provided to supply power to various types of electronic devices by employing an embedded mechanical power device which induces periodic forced vibration. CONSTITUTION: A non-power piezoelectric generation system comprises a power generator(100) including one or more springs, a vibration generator(200) including one or more rotors which generate periodic forced vibration with mechanical elastic energy, an electric power generator(300) including one or more piezoelectric devices which generate electric power from the forced vibration, a power amplification and conversion unit(400) regenerating the electric power outputted from the piezoelectric devices to a required level, and a controller(500) controlling the operation of the components using the power amplified or converted by the power amplification and conversion unit.
