[0027] The invention relates to an MFC-based disc type vibration energy collector, which mainly adopts a piezoelectric conversion method to convert vibrational mechanical energy into electric energy for output. Piezoelectric conversion has the advantages of simple structure, high power density and high output voltage. Therefore, it is a better way to use piezoelectric effect to harvest vibration energy.
[0028] Specifically, such as figure 1 , figure 2 As shown, the disc type vibration energy harvester based on the piezoelectric ceramic fiber sheet MFC (Macro FiberComposite) of the present invention comprises a laminated disc, a pressure ring 5, a base 8, an upper central mass 3, a lower central mass 7 and a guide Column 1. The base 8 is a disc-shaped base, and the central position of the disc-shaped base is provided with a downwardly recessed cylindrical groove, and the guide post 1 is vertically fixed on the top of the central position of the groove of the base 8, and th...
