A sensing film includes a base layer, a piezoelectric layer formed on the base layer, and a first electrode and a second electrode formed on the piezoelectric layer. The first and second electrodes are spaced apart and electrically insulated from each other. The first electrode includes a first connecting portion and a number of first extending portions coupled to the first connecting portion. The second electrode includes a second connecting portion and a number of second extending portions coupled to the second connecting portion. The first connecting portion and the second connecting portion are spaced apart and face each other. The first extending portions extend from a side of the first connecting portion toward the second connecting portion. The second extending portions extend from a side of the second connecting portion toward the first connecting portion. The first extending portions and the second extending portions are alternately arranged.
