The charger 5 is mounted on the strip 3 and electrically connected to the signal line 45. When implemented, the charger 5 can be designed to be mounted and fixed to the belt body 3, or is designed to be detachably mounted to the belt body 3. When the detachable type is designed, for example, being fastened to or worn by the strip 3, the charger 5 and the signal line 45 are permeable to the conductive electrode or the conductive terminal. Electrically connected, but the electrical connection between the charger 5 and the signal line 45 is not limited to the above type, and the manner in which the charger 5 is mounted on the strip 3 is not the focus of the present invention. Therefore, it will not be detailed.

The piezoelectric elements 44 force the piezoelectric elements 44 to deform to release electrical energy, and the transmission line 55 transmits the electrical energy generated by the piezoelectric elements 44 to the energy storage module 52 for storage. The elastic member 46 is elastically stretched by the traction block 42 to accumulate a return elastic force.

When the user exhales and the abdomen retracts, the complex elastic force of the elastic member 46 drives the traction block 42 to return to the reset state. At this time, the piezoelectric element 44 which is originally deformed by the elastic deformation is reshaped.

By this design, the power generation belt can synchronously expand and expand and contract during the repeated expansion and contraction of the abdomen, and continuously drive the piezoelectric elements 44 to generate output electric energy. And because the human body breathing will continue for 24 hours, whether it is standing, sitting or lying down, the belt head can continue to generate electricity with the breathing, and is not limited by whether the human body is carrying on.
