PURPOSE: An electricity-generable hula hoop is provided to generate power during exercise, thereby improving exercise effectiveness, and improving energy efficiency. CONSTITUTION: An electricity-generable hula hoop comprises a piezoelectric member(100), a transfer part(110), a piezoelectric device(120), and a connection part(130). A plurality of piezoelectric elements are comprised. The transfer part absorbs and transfers pressure generated by rotation. A plurality of the piezoelectric devices is mounted to a inner circumference and an outer circumference. The piezoelectric device converts the pressure to electricity. The connection part converts the pressure to electricity. The connection part connects the transfer part and the piezoelectric device each other.
