Claim Text:
1. A traffic sensor, comprising: (a) a flexible substrate having a top surface; (b) a piezoelectric structure, that includes a dense plurality of vertically-aligned piezoelectric elongated nanostructures, extending from the first electrode layer, the piezoelectric structure having a top end; (c) an insulating layer infused into a portion of the piezoelectric structure at the top end of the piezoelectric structure; (d) a first electrode layer disposed below the flexible substrate; (e) a second electrode layer disposed on top of the insulating layer so that the insulating layer electrically isolates the second electrode layer from the top end of the piezoelectric structure; and (f) a packaging layer disposed around the substrate, the first electrode layer, the piezoelectric structure, the insulating layer and the second electrode layer.
