ABSTRACT:
A ballistic fuse, which converts mechanical energy derived from the initial firing to stored electrical energy used to energize a later detonation, having piezoelectric polymer film strip with oppositely polarized layers on opposite surfaces, is pre-folded end to end before pleating and stacking in order to place both halves of a surface layer of one polarity into mutually contacting relationship, thereby reducing the risk of short circuits, and furthermore to double the bend radius required for pleating, thereby decreasing the risk of hinge failure due to bending stress at the pleated folds, and the continuous pattern of circles joined side by side in each layer is printed with conductive silver ink on the polymer film to eliminate the necessity of joining surfaces of like polarity with individual leads.
