The invention by enabling to use the electric energy converted by the piezoelectric element as a power source for operating the treadmill so provided with a plurality of piezoelectric elements for converting the mechanical energy supplied by the user on the staging of the treadmill into electric energy soon as the electricity consumption savings can be simultaneously running machine in the space where no power outage or when the power supply is continuously used, can be checked in the exercise planning exercise possible using the stride and after the use of a treadmill ended its work it even if not stop, as well as to automatically shut down the operation of the running machine in accordance with the stored presence or absence of the electric energy generated from the piezoelectric element provided with a safety strap charging of a mobile terminal, such as can be secured effectively the user's safety, and at the same time smartphone and who is using the piezoelectric element can be mounted on the treadmill-type development.
This self-generation-type running machine using the preferred piezoelectric element according to the embodiment is lower in the invention include orbit belt onto the additional scaffolding is infinitely rotated in the lower direction and having a front has been provided with a control unit for controlling the rotation of the orbiting belts and running machine main body, and a plurality of piezoelectric elements to the footrest portion spaced array on and the mechanical energy supplied by the user for conversion into electric energy, is provided between the piezoelectric element and the track belt, the mechanical energy by the user, the and the pressing plate so evenly applied to the piezoelectric element side, and provided inside the footrest portion and is electrically connected to the piezoelectric elements and a controller characterized in that it is included, the control means is electrical energy converted from the piezoelectric element to be charged and distribution It shall be.
