System and Method for Electric Power Generation Using Structured Stacked Piezoelectric Arrays

摘要

A piezoelectric power generation system includes a housing defining an opening therethrough and a support structure disposed within the housing, the support structure comprising a plurality of portions. The piezoelectric power generation system also includes one or more piezoelectric elements disposed between two of the plurality of portions of the support structure within the housing. Movement or vibration in the support structure compresses the one or more piezoelectric elements, wherein the one or more piezoelectric elements generate electric energy when compressed. The piezoelectric power generation system further includes one or more exciters coupled to the support structure, wherein the exciters move or vibrate when acted on by a flow of fluid, wherein the motion of vibration of the one or more exciters is translated to the support structure and ultimately to the one or more piezoelectric elements.

1. A piezoelectric power generation system, comprising:
a housing; a support structure disposed within the housing and comprising a plurality of portions, the support structure defined by an outer profile and an inner profile, the inner profile defining an orifice through which a tubing can be disposed, wherein a cross-section of the support structure is one of a plurality of geometric and non-geometric shapes; one or more stacked piezoelectric components disposed adjacent to one of the plurality of portions of the support structure or between two of the plurality of portions of the support structure; and one or more exciters coupled to the support structure and extending through and out of the housing, wherein the exciters, when actuated, transfer vibrational motion to the support structure, which actuates the one or more stacked piezoelectric components.
