Ultrasound-Responsive Systems as Components for Smart Materials

Smart materials can respond to stimuli and adapt their responses based on external cues from their environments. Such behavior requires a way to transport energy efficiently and then convert it for use in applications such as actuation, sensing, or signaling. Ultrasound can carry energy safely and with low losses through complex and opaque media. It can be localized to small regions of space and couple to systems over a wide range of time scales. However, the same characteristics that allow ultrasound to propagate efficiently through materials make it difficult to convert acoustic energy into other useful forms. Recent work across diverse fields has begun to address this challenge, demonstrating ultrasonic effects that provide control over physical and chemical systems with surprisingly high specificity. Here, we review recent progress in ultrasound–matter interactions, focusing on effects that can be incorporated as components in smart materials. These techniques build on fundamental phenomena such as cavitation, microstreaming, scattering, and acoustic radiation forces to enable capabilities such as actuation, sensing, payload delivery, and the initiation of chemical or biological processes. The diversity of emerging techniques holds great promise for a wide range of smart capabilities supported by ultrasound and poses interesting questions for further investigations.

“…Such multilayer structures entail using polymers and metals with different impedances and achieve a specific matching effect by adjusting the thickness of each layer. [83], graphene [84], carbon nanofibers (CNFs) [85], graphite [86], and candle-soot carbon nanoparticles (CSNPs) [87]. Using carbon nanomaterial-PDMS composites, the optoacoustic transducer has higher optoacoustic conversion efficiency and laser damage threshold than the metal-PDMS optoacoustic transducer.…”

Ultrasound is extensively studied for biomedical engineering applications. As the core part of the ultrasonic system, the ultrasound transducer plays a significant role. For the purpose of meeting the requirement of precision medicine, the main challenge for the development of ultrasound transducer is to further enhance its performance. In this article, an overview of recent developments in ultrasound transducer technologies that use a variety of material strategies and device designs based on both the piezoelectric and photoacoustic mechanisms is provided. Practical applications are also presented, including ultrasound imaging, ultrasound therapy, particle/cell manipulation, drug delivery, and nerve stimulation. Finally, perspectives and opportunities are also highlighted.

“…In micro- and nano-scale systems, surface-acoustic-wave (SAW)-based sensors have been widely studied. 5,6 Similar to the bulk devices mentioned above, SAW-based sensors detect changes in the physical properties ( e.g. , velocity, loss, resonant frequency) of an acoustic wave related to some measurable quantity of interest ( e.g.…”
