Apparatus and Method for Generating Power Downhole
First Claim
1. A downhole power generator comprising:
- a substantially tubular body;
a cover surrounding at least a portion of the body;
at least one piezoelectric element disposed in the body, the piezoelectric element engaged with the cover such that motion of the cover relative to the body causes the piezoelectric element to generate electric power.

Abstract
A downhole power generator comprises a substantially tubular body. A cover surrounds at least a portion of the body. At least one piezoelectric element is disposed in a cavity in the body, the piezoelectric element acting cooperatively with the cover such that motion of the cover relative to the body causes the piezoelectric element to generate electric power. A method for generating power downhole comprises disposing a cover around at least a portion of a substantially tubular body; disposing at least one piezoelectric element in the body; and engaging the piezoelectric element with the cover such that motion of the cover relative to the body causes the piezoelectric element to generate electric power.
