Embodiment Construction
[0018] Such as Figure 1-Figure 2 A PVDF piezoelectric film impact monitoring sensor is shown, including a PVDF piezoelectric film 1, a positive electrode layer 2, a negative electrode layer 3, an upper protective layer 6 and a lower protective layer 7;
[0019] The upper and lower surfaces of the PVDF piezoelectric film 1 cover the positive electrode layer 2 and the negative electrode layer 3 respectively;
[0020] The positive electrode wire 4 and the negative electrode wire 5 are connected to the positive electrode layer 2 and the negative electrode layer 3 by double-sided pressure welding;
[0021] The positive electrode layer 2 and the negative electrode layer 3 are covered with an insulating layer;
[0022] The surface of the lower protective layer 7 is provided with a groove 8, and the PVDF piezoelectric film 1 covered with the positive electrode layer 2, the negative electrode layer 3 and the insulating layer is placed in the groove 8 of the lower protective layer 7; ...
