Embodiment

Embodiment 1

A kind of human body power generation tester that the present embodiment provides, its vertical view as shown in Figure 1, its front view as shown in Figure 2, a kind of human body power generation tester, it is characterized in that, comprise base 1, left binding post 8, right binding post 2, right copper metal handle 5, left copper metal handle 7, right aluminum metal handle 3, left aluminum metal handle 6 and current sensor of the material that insulate.

Base 1 is circular, and its material is the acrylic material, realizes insulation.6 perforation are set on base 1, and 6 perforation are symmetrical along the center line of described base 1.For fear of the wearing and tearing of base 1 and base reverse side wire, the foot pad 4 of two above polyoxymethylene materials of base 1 bottom even distribution, in the present embodiment, the quantity of foot pad 4 is 4.

Right copper metal handle 5, right aluminum metal handle 3 and right binding post 2 are fixed on by contact screw in the perforation on center line right side of base 1, then connect by wire, and described right binding post 2 is connected with an input end of described current sensor by wire.
