Abstract: A sensor system, including: a dielectric material on a part body; and a sensor on the dielectric material, the sensor configured to provide impedance, capacitance, and resistance values and to alter one or more of the impedance, capacitance and resistance values responsive to a stress applied to the part body. Also disclosed is a method of making and a method of using the sensor system.

Abstract: Acoustic impedance matching devices and related methods are disclosed. An acoustic impedance matching device includes a first face for facing an acoustic transducer, a second face opposite the first face, and a lattice structure between the first face and the second face. The second is face curved to at least substantially conformally engage an inner surface of a tubing. An effective acoustic impedance of the lattice structure substantially matches a transducer acoustic impedance of the acoustic transducer to a tubing acoustic impedance of the tubing. A material acoustic impedance of a material of the lattice structure is greater than the effective acoustic impedance.
