<p>The present invention relates to a piezoelectric generator unit that uses a piezoelectric bimorph. This piezoelectric generator unit comprises: a cylindrical housing, a flywheel which rotates inside the housing through external power and which has a plurality of protrusions formed therein at regular intervals in the circumferential direction thereof, a fluid spraying apparatus which enables the flywheel to rotate by delivering the power through spraying fluid or air to the impeller of the flywheel, a plurality of piezoelectric materials which are radially provided and are brought into contact with the protrusions of the flywheel, thereby creating impact from which electricity is generated, and a central shaft which is mounted via the piezoelectric materials and the connection member. Therefore, this piezoelectric generator unit can effectively produce electric energy by transforming linear motions, even from small impacts and vibrations, into efficient rotational motions, enhance the efficiency of the generation by generating a large output even from a small input, and can be applied to diverse fields that use a moving load.</p> |
