Non-limiting examples of the present disclosure relate to devices, systems and methods of manufacture for an exemplary waveguide usable for acoustic signal transmission for non-destructive evaluation (NDE) of a wooden specimen. An exemplary waveguide comprises a mating portion for interfacing with a transducer horn of an ultrasonic transducer. The mating portion comprises an impact surface and a contact well that is fabricated within the impact surface so that the contact well is not contacted during an impact that drives the waveguide into wood. The contact well is utilized to connect the waveguide to a transducer horn. The waveguide further comprises a body portion that comprises a radiating component optimized for non-destructive evaluation (NDE) of wood and transmission of ultrasonic signal data. Further non-limiting examples describe an interfacing component for securing one or more devices to the waveguide as well as an extraction component that is configured to minimize damage to the waveguide during extraction.

A microfluidic-based device and system is disclosed for the high-throughput intracellular delivery of biomolecular cargo to cells (eukaryotic or prokaryotic) or enveloped viruses. Cargo integration occurs due to transient membrane permeabilization by exposure to bulk acoustic waves (BAWs) transduced from surface acoustic waves (SAWs) generated by a rapidly oscillating piezoelectric substrate. In this approach, temporary pores are established across the cellular membrane as cells are partially deformed and squeezed or subject to shearing forces as they travel through the vibrational modes created within the microfludic channel(s) of the device.

A 4D-perfused tumoroid-on-a-chip platform used in personalized cancer treatment. The platform includes a plate with a plurality of bottomless wells that resides atop a microfluidic channel layer, which in turn resides atop a surface acoustic wave (SAW) based sensor layer that is capable of measuring potential pH values of fluids disposed within the platform. The microfluidic channel layer includes a plurality of bioreactors, with each bioreactor including an inlet well, a culture well, and an outlet well. The inlet well, culture well, and outlet well form a closed system via fluid conduits spanning from the inlet well to the culture well, as well as from the culture well to the outlet well. Due to the fluid flow from the plate to the chip, and from the inlet well to the outlet well on the chip through the culture well, target cell (tumoroid) growth is promoted within the culture well.

A permanently installed monitoring system for corrosion under insulation (PIMSCUI) and a method for performing the monitoring of said system are provided. The objective of the invention by a fiber optic cable permanently mounted between walls of a pipeline and pipeline insulation surrounding the pipeline and placement of acoustic emitters along the length of the pipeline in mechanical contact with the optical fiber. The acoustic emitters send a pulsed acoustic signal towards the pipeline which is received by the optical fiber, the acoustic signal subsequently travels through the pipeline wall, reflecting from the inner diameter of the pipeline before the reflected pulse is received at the optical fiber.

The present invention provides a wireless temperature and humidity sensor and system, and measurement method. The wireless temperature and humidity sensor comprises a substrate, a feeding network, an antenna and surface acoustic wave resonators, wherein the surface acoustic wave resonators are fed by said feeding network through said antenna. Said surface acoustic wave resonator comprises a reference resonator and measuring resonators. The resonant frequency difference between said reference resonator and said measuring resonators is used to modulate the temperature and/or humidity to be measured. Said system can monitor both temperature and humidity simultaneously, or monitor humidity or temperature selectively. Furthermore, frequency drift caused by aging of the sensor material and the connector is effectively suppressed by the differential modulation, thereby improving long-term stability of measurement and avoiding recalibration.
