FOOTHOLD-TYPE PIEZOELECTRIC GENERATOR UNIT AND PIEZOELECTRIC GENERATOR SYSTEM INCLUDING SAME

摘要

The present invention relates to a foothold-type piezoelectric generator unit and a piezoelectric generator system including the same. According to the present invention, the piezoelectric generator system comprises: at least one piezoelectric generator unit which includes unit piezoelectric sections, in which piezoelectric layers are formed on at least one surface of an elastic substrate and cushion layers are formed on both sides of the elastic substrate, an electrode substrate on which one or more unit piezoelectric sections are arranged, and an insulating substrate for supporting the electrode substrate; at least one rectifying circuit which converts AC power that is generated by the transformation of the piezoelectric layers of the piezoelectric generator unit into DC power; and an elastic mat section which covers the piezoelectric generator unit.
