“…Ultrasonic sensors are well-developed instruments and hold a long tradition. They are used for non-destructive, non-invasive and accurate measurements of technical and bio-liquids with a broad variety of chemical/biological compositions [ 1 ] as well as for many other applications with traditional and new transducer devices, just recently e.g., [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. In contrast to acoustic microsensors such as the quartz crystal microbalance (QCM), they apply longitudinal acoustic waves which are able to propagate through the whole volume of matter.…”

The article focuses on a high-resolution ultrasound sensor for real-time monitoring of liquid analytes in cylindrical pipes, tubes, or capillaries. The development of such a sensor faces the challenges of acoustic energy losses, including dissipation at liquid/solid interface and acoustic wave radiation along the pipe. Furthermore, we consider acoustic resonant mode coupling and mode conversion. We show how the concept of phononic crystals can be applied to solve these problems and achieve the maximum theoretically possible Q-factor for resonant ultrasonic sensors. We propose an approach for excitation and measurement of an isolated radial resonant mode with minimal internal losses. The acoustic energy is effectively localized in a narrow probing area due to the introduction of periodically arranged sectioned rings around the tube. We present a sensor design concept, which optimizes the coupling between the tubular resonator and external piezoelectric transducers. We introduce a 2D-phononic crystal in the probing region for this purpose. The Q-factor of the proposed structures show the high prospects for phononic crystal pipe sensors.

“…In addition, recent ultrasonic acoustic modeling has shown the ability to detect changes in density distribution and temperature effects during cycling. 22 This recent ultrasonic acoustic technique uses high frequency compressional wave pulses formed by piezoelectric transducers to record changes in material properties. Compressional pressure waves travel through both solid and liquid materials, while transverse waves only travel through solid materials (due to the non-shearing nature of liquids).…”

Lithium-ion batteries represent a dominant technology in the current energy storage market. However, many aspects of these batteries are still poorly understood, and proper engineering of these aspects will lead to increased cycle life and performance parameters. In particular, the electrode/electrolyte interface is still an actively researched topic and is notoriously difficult to study. An ultrasound acoustic characterization technique is introduced to probe the electrode/electrolyte interface in operando using signal amplitude analysis. This technique gives insight into lithium ion concentration accumulation and depletion at the electrode/electrolyte interface, and these findings are consistent with Dualfoil model simulations.

“…22 The state differences of internal materials can be analyzed on the basis of the signal transmission changes in acoustic waves within a battery as ultrasonic detection is highly sensitive to material properties. 1 Gold et al, 23 Hsieh et al, 24 Popp et al, 25 Kim et al, 26 Ladpli et al, 17,27 Wu et al, 28 Zhao et al, 29 Copley et al, 30 Song et al 31 and Bommier et al 32 found that the time of flight (TOF) results of ultrasonic signal had linear relationships with the state of charge (SOC) and state of health (SOH) during charging and discharging of the battery. Moreover, Bhadra et al 22 tracked ultrasonic transmission signal with respect to the discharge process under different current rate and identified a direct correlation between changes in the acoustic waves and the physical transitions of active materials.…”
