Patent number: 8857261Abstract: A sensing device and a method of attaching the sensing device to a target object is disclosed. The substrate of the sensing device has one or more bonding material vias that allows the bonding material used to attach the substrate to the target object to flow from one side of the substrate to the other side of the substrate. The bonding material forms rivets to secure the substrate to the target object and to secure the layers of the substrate to each other.Type: GrantFiled: April 12, 2012Date of Patent: October 14, 2014Assignee: General Electric CompanyInventors: Matthew Harvey Krohn, Paul Aloysius Meyer, Nathan John Smith, Fred Timothy Matthews

Publication number: 20120294124Abstract: A piezoelectric sensing device is described for measuring material thickness of target such as pipes, tubes, and other conduits that carry fluids. The piezoelectric sensing device comprises a substrate such as a flexible circuit material, a piezoceramic element, and a solder layer disposed therebetween. These features are arranged in manner that provides a low-profile measurement device suitable for high-temperature applications such as those applications in which the temperature exceeds 120° C. Embodiments of the piezoelectric sensing device can be configured for use as stand-alone units separately located on the target or for use as a string of sensing elements coupled together by way of the flexible circuit material.Type: ApplicationFiled: August 6, 2012Publication date: November 22, 2012Inventors: Matthew Krohn, Paul Aloysius Meyer, James Norman Barshinger, Ying Fan, Fred Matthews, Nathan Smith
