An ultrasonic inspection system includes an ultrasonic sensor and a control device. The ultrasonic sensor has a piezoelectric element that transmits and receives ultrasonic waves and plate portions and that are arranged so as to contact an upper surface of the piezoelectric element and have different thicknesses. The control device acquires a propagation time of a reflected wave reflected on an upper surface of the plate portion, calculates a sound velocity of the plate portion using the propagation time of the reflected wave and a thickness of the plate portion, and corrects a sound velocity of a pipe and acquires a sound velocity of the plate portion based on the calculated sound velocity. In addition, the control device acquires a propagation time of a reflected wave reflected on an upper surface of the plate portion, and calibrates a time axis based on the propagation time of the reflected wave, a thickness of the plate portion, and the sound velocity of the plate portion.

An ultrasonic transducer and a method for producing an ultrasonic transducer are disclosed wherein the ultrasonic transducer has outstanding media resistance and a simpler construction by reducing the number of individual parts, so that the ultrasonic transducer can be produced in a fully-automated production process. The ultrasonic transducer, particularly for measurement of fluid volumes, can include a housing in which a contact element and a piezoceramic are arranged, wherein the piezoceramic includes two electrodes of differing polarity which are attached to different sides of the piezoceramic, wherein contact areas of the two electrodes for making electrical contact are disposed on a same side of the piezoceramic and the contact element includes at least two contact sections of differing polarity which are in electrically conducting contact with the contact areas of the two electrodes of corresponding polarity.

A method of measuring dissociation of the biomolecular bonds in one or multiple sample wells using super-resolution force spectroscopy (SURFS). SURFS utilizes precise ultrasound radiation to exert an acoustic radiation force on the biomolecular bonds labeled with magnetic particles. The force-induced dissociation of the protein bonds labeled with magnetic particles may be measured as a reduced magnetic signal by a magnetic sensor. The force resolution allows for differentiating biomolecular bonds with an extremely high level of precision. The biomolecular bonds include protein-protein, protein-nucleic acid, nucleic acid-nucleic acid, small molecule-protein, and small molecule-nucleic acid interactions.

A vibrating device includes a vibrating element, a support, and a connector. The vibrating element includes a vibrating body that is tubular and includes a first opening end surface and a second opening end surface. The support extends in an axial direction and supports the vibrating body, the axial direction being a direction connecting the first opening end surface and the second opening end surface of the vibrating body. The connector connects the vibrating body and the support to each other. The vibrating body vibrates in a breathing vibration mode to generate a first node and a second node on the vibrating element at different positions in the axial direction. The connector is positioned between the first node and the second node.
