Abstract
A self-powered sensor array (SPSA) for sensing environmental parameters along a drillstring includes an outer collar having moveable member retainers with moveable members movably located in the moveable member retainers. An inner ring is rotatably supported within the outer collar with bearing elements on an outer surface of the inner ring positioned to displace the moveable members relative to the moveable member retainers in response to relative rotation between the inner ring and the outer collar. Shape memory material elements are arranged in a respective moveable member retainer. Distance sensors are configured to sense a gap responsive to a shape change of the respective shape memory material element and a displacement of the respective moveable member. Power generation components are configured such that, in response to the relative rotation, the bearing elements displace a particular moveable member into a particular moveable member retainer, generating an electric charge.
