Abstract: An acoustofluidic device is provided comprising a) a substrate, and b) an ultrasound transducer attached to, or in contact with, the substrate. The substrate and the ultrasound transducer combined have a first set of acoustic natural system resonances determined by the material and the dimensions of the substrate and ultrasound transducer. Each system resonance comprises a resonance frequency and a resonance quality factor. The device further comprises c) a microfluidic cavity provided in the substrate and containing a fluid, the cavity having a second set of acoustic natural cavity resonances, each having a resonance frequency and a resonance quality factor, determined by the dimensions of the cavity and the speed of sound in the fluid. The material and the dimensions of the substrate and ultrasound transducer are selected so that at least one individual cavity resonance has a resonance frequency corresponding to the frequency of a minimum in an impedance spectrum of the ultrasound transducer. Method of producing the acoustofluidic device, as well as method of tracking a resonance frequency and performing an acoustofluidic operation are also provided.

Abstract: A compact portable ultrasonic inspection apparatus and method of non-destructive inspection of an object. A probe of the apparatus has a stationary cavity frame assembly with an agile ultrasound stylus, being a transducer and an acoustic coupling member, located therein and on which a motion system induces random or controlled motion of the stylus, to pivot the transducer about a point where the coupling member contacts a surface to be inspected. Three landing elements surround the coupling member, configured to hold the frame assembly to the surface. A sequence of oblique angle ultrasound measurements collected at measured transducer orientations generate polar scans of backscattered acoustic energy from within the object and automatically derive geometric measurements and/or ascertain internal health-condition information about the object. The apparatus finds application in-situ non-destructive testing (NDT) inspection of anisotropic or composite materials used in safety-critical objects or structures.

Abstract: Non-destructive testing of an elongate object can include using an adaptable apparatus to support objects having different cross-sectional profiles. For example, an adaptable inspection fixture can support inspection probes for acoustic or eddy current inspection, as illustrative examples. Generally, the apparatus comprises opposing portions which are pivotable and connected by a linkage to maintain the opposing portions in a specified orientation relative to each other while permitting independent rotational orientations of each respective opposing portion such as to accommodate test objects. For example, the opposing portions can be substantially parallel across multiple configurations. Optionally, the apparatus can maintain a specified orientation of one or more radius probes with respect to an object under test.
