A method includes filling a cavity of a form defined by one or more boundaries with an uncured concrete mixture such that the uncured concrete mixture contacts or envelops a piezoelectric sensor within the form, receiving one or more electrical signals from the piezoelectric sensor as the uncured concrete mixture cures within the form to define a concrete sample, determining an electrical signal-frequency spectrum of the electrical signal(s) received from the piezoelectric sensor, determining one or more resonant frequencies of the concrete sample based on the electrical signal-frequency spectrum, determining a Young's modulus of the concrete sample based on the one or more resonant frequencies thereof, and outputting the determined Young's modulus or information based on the determined Young's modulus.

Methods, systems, and apparatuses are disclosed for non-destructively inspecting a substrate by measuring the Doppler effect in sound waves comprising wide bandwidth ultrasound wavelengths generated from a piezoelectric polymer coating material with the sound waves read by a laser in communication with a Doppler velocity meter.

A wireless ultrasound sensor 404 for non-destructive testing of a test object 502, the sensor comprising: an ultrasound transducer 406; a first induction coil 408, electrically coupled to the ultrasound transducer; a second induction coil 414, electrically coupled in parallel with the first induction coil; wherein the first and second induction coils are arranged to enable the transducer to be inductively operated by a remote device 504; and wherein the diameter of the second induction coil is greater than the diameter of the first induction coil.

The present invention discloses a method for extending the detection range of a structural health monitoring (SHM) system. A structure being monitored is scanned multiple times. A scan with no collection delay covers an original detection area of the SHM system. Scans with collection delays cover extended detection areas. The SHM system's detection range is extended when results of multiple scans with different collection delays are combined.

The present disclosure relates to a device for emission and reception of ultrasonic signal to and from a surface under survey, the device includes a stationary shaft part; and two or more wheel assemblies attachable to a stationary shaft part. Each wheel assembly includes an orbital inner ring, an orbital outer ring, and one or more transducers mounted on the outward facing surface of the orbital inner ring protruding radially from the orbital inner ring. The orbital outer ring being arranged radially outside the transducer modules with the orbital inner ring and is rotating together when the wheel assembly is rolled along a surface to be surveyed.

Acoustically mediated pulsed radiation sources, phased arrays incorporating the radiation sources, and methods of using the radiation sources and phased arrays to generate electromagnetic radiation via magnetic dipole emission are provided. The radiation sources are based on a superlattice heterostructure that supports in-phase magnetic dipole emission from a series of magnetic insulator layers disposed along the length of the heterostructure.

Systems and methods are provided for enhanced vacuum bags. One embodiment is a method that includes placing a laminate comprising uncured fiber reinforced polymer onto a mandrel, laying up a vacuum bag, which includes integral ultrasonic transducers within a gas-impermeable layer, atop the laminate, and sealing the vacuum bag to the mandrel. The method also includes drawing a vacuum on the laminate via the vacuum bag, removing gas between the integral ultrasonic transducers and the laminate, and interrogating the laminate with the integral ultrasonic transducers.

A clamping element comprises a clamping body, such as a screw, having an ultrasound sensor fixed to the head. The sensor transmits and collects ultrasound that propagates along the shaft of the screw between two flat and parallel base surfaces, to measure a physical quantity connected to the clamping force that acts on the screw. A cap-shaped cover element can be removably affixed to the screw head and houses a wired or wireless communication module, a controller, power supply means, and possibly additional sensors. A memory can be stably fixed to the ultrasound sensor to store screw-characteristic data. A monitoring system can collect and process the data of all the clamping elements with a single processor.
