Further, small electrode is rectangle, and small electrode is positioned at one jiao of large electrode, and small electrode and large electrode are combined into complete rectangle.
Further, piezoelectric patches is one or more layers.
The method that the utility model produces electric energy is: when mouse left button or right button are pressed, flexural deformation is produced together with the piezoelectric that its back side is pasted, due to direct piezo electric effect, the surface that piezoelectric patches is relative produces positive and negative charge, by the electrode on apparent surface, electric charge is derived, power storage is got up, for mouse is powered with memory circuit by electric energy conversion.
The method that the utility model detects mousebutton is: when mouse left button or right button are pressed, the piezoelectric that the button back side be pressed is pasted produces flexural deformation together, due to direct piezo electric effect, the surface that piezoelectric is relative produces positive and negative charge, the key-case of mouse can be judged by the voltage on this surface of circuit supervision.
The utility model has the advantages that:
1. by piezoelectric, the mechanically deform produced during mousebutton can be converted into electric energy, for mouse is powered, achieve the self-powered of mouse, avoid the problem changing battery.
2. the voltage produced when being out of shape by detecting piezoelectric judges key-case, avoids the elastic sheet switch of practical conventional mouse, makes mouse have noiseless feature.
3. produce electric energy and detect key-case and realize on same a slice piezoelectric, structure is simple.
