Abstract
A piezo sensor having an inner conductor having an inner conductor segment, where the inner conductor segment forms a tubular sidewall having a break, and also having an interior surface and an exterior surface; a plurality of individually polarized piezoelectric members, each having an inner face and an outer face, and each inner face contacting the first conductor exterior surface, each piezoelectric member being adjacent to another on the exterior face of the inner conductor, forming sets of adjacent faces; an outer conductor having an outer conductor segment forming a tubular sidewall having a break, the outer conductor having an interior surface and an exterior surface, where the interior surface contacts the outer face of the piezoelectric members; and where the break of the outer conductor segment is alignable with adjacent faces of two of the plurality of piezoelectric members, and further being alignable with the break of the inner conductor segment.
