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.

Sensing device and method of attaching the same

A piezoelectric sensing device is described for measuring material thickness of targets such as pipes, tubes, and other conduits that carry fluids. The piezoelectric sensing device includes a piezoelectric element mounted to a flexible circuit with glass reinforced polyimide C-stage cover layers surrounding a pure polyimide C-stage core.

Device for measuring material thickness

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&#xb0; 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.
